knowledge of mechanical theory, tool use and shop procedures is necessary to perform the service work safely and satisfactorily.
Use only genuine Polaris service parts.
Cleanliness of parts and tools as well as the work area is of primary importance. Dirt and foreign matter will act as an abrasive
and cause damage to precision parts. Clean the snowmobile before beginning service. Clean new parts before installing.
Watch for sharp edges which can cause personal injury, particularly in the area of the tunnel. Protect hands with gloves when
working with sharp components.
If difficulty is encountered in removing or installing a component, look to see if a cause for the difficulty can be found. If it is
necessary to tap the part into place, use a soft face hammer and tap lightly.
Some of the fastenersin the snowmobile were installed with locking agents. Use of impact driversor wrencheswill help avoid
damage to fasteners.
Always follow torque specifications asoutlined throughout this manual. Incorrect torquing may lead to serious machine
damage or, as in the case of steering components, can result in injury or death for the rider(s).
If a torquing sequence is indicated for nuts, bolts or screws, start all fasteners in their holes and hand tighten. Then, following
the method and sequence indicated in this manual, tighten evenly to the specified torque value. When removing nuts, bolts or
screws from a part with several fasteners, loosen them all about 1/4 turn before removing them.
If the condition of any gasket or O-Ring isin question, replace it with a new one. Be sure the mating surfaces around the gasket
are clean and smooth in order to avoid leaks.
Some procedures will require removal of retaining rings or clips. Because removal weakens and deforms these parts, they
should always be replaced with new parts. When installing new retaining rings and clips use care not to expand or compress them
beyond what is required for installation.
Because removal damages seals, replace any oil or grease seals removed with new parts.
Polaris recommends the use of Polaris lubricants and greases, which have been specially formulated for the top performance
and best protection of our machines. In some applications, such as the engine, warranty coverage may become void if other brands
are substituted.
Grease should be cleaned from parts and fresh grease applied before reassembly of components. Deteriorating grease loses
lubricity and may contain abrasive foreign matter.
Whenever removing or reinstalling batteries, care should be taken to avoid the possibilityof explosion resulting in serious
burns. Always disconnect the negative (black) cable first and reconnect it last. Battery electrolyte contains sulphuric acid and is
poisonous! Serious burns can result from contact with the skin, eyes or clothing.ANTIDOTE:External - Flush with water.
Internal - Drink large quantities or water or milk. Follow with milk of magnesia, beaten egg, or vegetable oil. Call physician
immediately. Eyes - Flush with water for 15 minutes and get prompt medical attention.

PISTON WASH AND SPARK PLUG COLOR
Changing temperature, barometer, altitude, and fuelsupply are just a few of the factors thatcan affect the day today performance
of your engine. That is why using Exhaust Gas Temperatures (EGTs) are important for maintaining optimum performance. There
are two methods for helping you determine what the EGTs are for your machine. Piston wash and the coloring of your spark
plug.The piston wash is by far the most valuable tool in concluding EGTs, with the spark plug color running a distant second.
Use the illustrations below to help youestablish the EGTs for your machine.
nIf the wash is 1/4” - 3/8” and cocoa
brown, the machine’s EGTs are just right.
nWet and Black wash indicates too rich a fuel
mixture
nA dry, ash colored piston indicates too lean a
mixture for the operating conditions.
nIf the plug is light to cocoa brown, the ma-
chine’s EGTs are just right.
nIf the plug is wet or very dark, the fuel is
running too rich.
nA ash white plug with speckles indicates too
lean a mixture for the operating conditions.
Piston Wash Spark Plug Color
Once the proper jetting is established, youcan reference the EGT gaugefor your baseline numbers. Then, if there is a rise or
fall of 25 degrees, you must jet accordingly to return your EGTs to the baseline numbers.

CYLINDER INSPECTIONS
CYLINDER HEAD INSPECTION
Inspect each piston dome area of the cylinder head for warping by plac-
ing a straight edge across the dome area.
With a feeler gauge measure any gap under the straight edge.
Replace cylinder head if measurement exceeds the service limit of
.003” (.08mm).
NOTE:

CYLINDER MEASUREMENT
Inspect each cylinder for wear, scratches, or damage. If no damage is evident, measure the cylinder for taper and out of round
with a telescoping gauge or a dial bore gauge. Measure the bore 1/2, from the top of the cylinder; in line with the piston pin and
90_to the pin to determine if the bore is out of round. Repeat the measurements at the middle of the cylinder and the bottom
of the cylinder to determine taper or out of round at the bottom. Use the chart below and record all measurements.

Check piston for scoring or cracks in piston crown or pin area. Excessive carbon buildup below the ring lands is an indication
of piston, ring or cylinder wear.
For Libertytengines, measure piston outside diameter at a point 3/8” (10mm) up from the bottom of the skirt at a 90_angle
to the direction of the piston pin (diagram A).
For Fuji engines, measure piston outside diameter at a point that is 1/2” (12.7mm) up form the bottom of the skirt at a 90_angle
to the direction of the piston pin (diagram A).
NOTE: The piston must be measured at this point to provide accurate piston to cylinder measurements.
Subtract this measurement from the minimum cylinder measurement recorded previously when you recorded the cylinder mea-
surements. If clearanceexceeds the service limit, the cylinder should be re-bored and new pistons and rings installed. Refer to
piston to cylinder clearance limits in the General Information section listed per model.
PISTON RING INSTALLED GAP
Position the ring 1/2“ (1.3 cm) from the top of the cylinder using the piston to push it squarely into place. Measure installed gap
with a feeler gauge at both the top and bottom of the cylinder (diagram B).
NOTE:
A difference in end gap indicates cylinder taper. The cylinder should be measured for excessive
taper and out of round.Replace rings if the installed end gap exceeds the service limit.
NOTE: Always check piston ring installed gap after re-boring a cylinder or when installing new rings.
NOTE: Piston rings are installed with marking or beveled side up see diagram D.

30. GENERAL INFORMATION
2.12
CYLINDER HONING
The cylinder bore must be de-glazed whenever new piston rings are installed. Alight honing with finestones removes only a
very small amount of material. A proper crosshatch pattern is important to provide a surface that will hold oil, and allow the rings
to seat properly. If the crosshatch is too steep, oil retention will be reduced. A crosshatch angle which is too shallow will cause
ring vibration, poor sealing, and overheating of the rings due to blow-by and reduced contact with the cylinder wall. Service life
of the pistons and rings will be greatly reduced.
CYLINDER HONE SELECTION
A Nikasil cylinder can be lightly honed with
a soft stone hone but can not be oversized.
NOTE:
DE--GLAZING
If cylinder wear or damage is minimal, honing the cylinder lightly with
finish stones. Follow theprocedure outlined above
HONING TO OVERSIZE (340 AND 500 FUJI ENGINES ONLY)
If cylinder wear or damage is excessive, it will be necessary to oversize the cylinder using a new oversize piston and rings. This
may be accomplished by either boring the cylinder and then finish honing to the final bore size, or by rough honing followed by
finish honing.Portable rigid hones are not recommended for oversizing cylinders, cylinder boring, and finish honing.
The use of an arbor type honing machine is recommended.
NOTE:
For oversize honing always wet hone using honing oil and a coarse roughing stone. Measure the new piston at room temperature
(see piston measurement) and rough hone to the size of the piston or slightly larger. Always leave .002” - .003“ (.05 - .07 mm)
for finish honing. Complete the sizing with fine grit stones to provide the proper cross-hatch finish and required piston clearance.
Inspect cylinder for taper and out-of-round. Taper orout-of-round on the finished bore should not exceed.0004“ (.002mm).
NOTE: Always check piston to cylinder clearance and piston ring installed gap after boring/honing is complete.
HONING PROCEDURE
Wash the cylinder with solvent.
Clamp the cylinder in a soft jawed vise by the exhaust port studs.
Place hone in cylinder and tighten stone adjusting knob until stone contacts the cylinder walls (DO NOT OVERTIGHTEN).
Cylinders may be wet or dry honed depending on the hone manufacturer’s recommendations. Wet honing removes more material
faster and leaves a more distinct pattern in the bore. Using a 1/2“ (13 mm) drill motor rotating at a speed of 300-500 RPM
,run
the hone in and out of the cylinder rapidlyuntil cutting tensiondecreases. Remember to keep the hone drive shaft centered to
prevent edge loading and always bring the stone approximately 1/2“ (1.3 cm) beyond the bore at the end of each stroke.
Release the hone at regular intervals to inspect bore size and finish.

PORT CHAMFERING
Remove the sharp edges at the bottom and top of each port whenever boring or honing is performed. Make sure there are no sharp
edges.
IMPORTANT:
It is very important that the cylinder be thoroughly cleaned after honing to remove all grit material.
Wash the cylinder in a solvent, then in hot soapy water. Pay close attention to areas where the cylinder
sleeve meets the aluminum casting (transfer port area). Use electrical contact cleaner if necessary to
clean these areas. Rinsethoroughly, dry with compressed air, andoil the bore immediately with Polaris
Premium 2 Cycle Lubricant.
CLEANING THE CYLINDER AFTER HONING
It is very important that the cylinder be thoroughly cleaned after honing to remove all grit material. Wash the cylinder in a solvent,
then in hot soapy water. Pay close attention to areas where the cylinder sleeve meets the aluminum casting (transfer port area).
Use electrical contact cleaner if necessary to clean these areas. Rinse thoroughly, dry with compressed air, and oil the bore im-
mediately with Polaris Premium 2 Cycle Lubricant.
Always check piston to cylinder clearance and piston ring installed gap after boring/honing is
complete!
NOTE:
CRANKCASE INSPECTION / BEARING FIT
Any time crankshaft bearing failure occurs and the case isto be reused,
Polaris recommends checking the bearing fit into the case halvesusing
the following procedure.
With case halves cleaned, press a replacement bearing into each of the
main bearing journals to determine a basic amount of press fit.
NOTE: Crankcase Bearing Interference Fit:.001” -- .002” (.026 -- .051mm)
Do a comparison check of all journals by manually forcing the bearing into the bearing seats noting if
any are noticeably loose or tight. Normal hand installation will be an indication of the recommended
interference fit. If the bearing falls out of the case when the case is inverted, or if the crankcase bear-
ing surface is severely galled or damaged, the case should be replaced
NOTE:
CRANKSHAFT MAIN BEARING INSPECTION
Clean crankshaft thoroughly and oil main and connecting rod bearings with Polaris engine oil. Carefully check each mainbearing
on the shaft.
Due to extremely close tolerances, the bearings must be inspected visually, and by feel. Look for signs
of discoloration, scoring or galling. Turn the outer raceof each bearing. The bearings should turn
smoothly and quietly. Theinner race of each bearing should fit tightly on the crankshaft. The outer
race should be firm with minimal side to side movement and no detectable up and down movement.
Replace any loose or rough bearings.
NOTE:

32. GENERAL INFORMATION
2.14
CONNECTING ROD (BIG END) BEARING INSPECTION
Measure connecting rod big end side clearance with a feeler gauge. 500/600 LibertytEnginesshould have a clearance of
(.28 --.75mm) and 700/800/900 LibertytEnginesshould have (.28 -- .70mm) and be equal on all rods (within .002″) Rotate rod
on crankshaft and check for rough spots. Check radial end play in rod by supporting rod against one thrust washer and alternately
applying up and down pressure. Replace bearing, pin, and thrust washers if side clearance is excessive or if there is any up and
down movement detectable in the big end bearing.
Specialized equipment and a sound knowledge
of crankshaft repair and straightening is required
to perform crankshaft work safely and correctly.
Crankshaft repair should be performed by
trained Polaris service technicians in a properly
equipped shop.
NOTE:
PISTON PIN / NEEDLE BEARING INSPECTION
Clean needle bearing in solvent and dry with compressed air.
Inspect needle cage carefully for cracks or shiny spots which indicate
wear. Replace needle bearings if worn or cracked, and always replace
them if piston damage has occurred.
Visually inspect piston pin for damage, discoloration, or wear. Run your
fingernail along the length of the pin and replace it if any rough spots,
galling or wear is detected.
CONNECTING ROD SMALL END INSPECTION
Clean small end of connecting rod and inspect inner bore with a magni-
fying glass. Look for any surface irregularities including pitting, wear,
or dents.
Run your fingernail around the inside of the rod and check for rough
spots, galling, or wear.
Oil and install needle bearing and pin in connecting rod. Rotate pin
slowly and check for rough spots or any resistance to movement. Slide
pin back and forth through bearing while rotating and check for rough
spots.
With pin and bearing centered in rod, twist ends back and forth in all
directions to check for excessive axial play. Pull up and down evenly
on both ends of pin to check for radial play. Replace pinandbearing
if there is any resistance to rotation or excessive axial or radial move-
ment. If play or roughness is evident with a new pin and bearing, replace
the connecting rod.

CAUTION:
Disconnect battery ground cable and ALL spark plug high tension leads: ground high tension

Polaris crankshafts are pressed together or ‘‘indexed” so the connecting rod journal center lines are 180_(twins).
It is sometimes necessary to check multi-cylinder crankshafts to verify that one cylinder has not been forced out of position rela-
tive to the other cylinder or cylinders. Some causes for out-of-index crankshafts include but are not not limited to:
SHydraulock from water or fuel
SImpact to drive clutch from foreign object or accident
SAbrupt piston or other mechanical failure
SEngine lock--up due to drive belt failure
REQUIRED SERVICE:
Belt Removal, Drive Clutch Removal
Securely fasten a degree wheel on the flywheel or PTO end of crankshaft. Use a large degree wheel for more accuracy, and make
sure it is mounted concentrically with the crankshaft center line.
Sharpen a coat hanger or section of welding rod and anchor it to a convenient spot. Point the sharpened end at the outer perimeter
of the degree wheel.
Install a dial indicator into the magneto end cylinder spark plug hole. (The ignition timing is referenced by the magneto end.)
With the indicator installed on the MAG cylinder rotate the engine to bring the piston to top dead center (TDC).
Locate TDC as accurately as possible by finding the center of the point where there is no piston movement then ‘‘Zero” the dial
indicator at this point. Continue to rotate the crankshaft in the normal direction of rotation until the dial indicator reads .100”
(2.54mm) after top dead center (ATDC).
Bend the pointer or move the degree wheel until the pointer aligns with a 180_mark on the degree wheel.
With the pointer aligned, make sure the degree wheel and pointer are secured and will not move out of position. Re-check accura-
cy of this location a few times. The pointer should align with the 180_mark when the dial indicator reads .100“ (2.54mm) ATDC.
IMPORTANT:
Do not move the crankshaft, degree wheel or pointer after the initial setting on the MAG end cylinder --
simply read the wheel and dial indicator.
Remove the dial indicator and install in PTO cylinder. Repeat finding TDC. Note the degree wheel indication when the dial indica-
tor reads .100” ATDC. It should be 180_ (±2_) from the MAG cylinder mark.

SDifficulty calibrating carburetor (repetitive plug fouling on one cylinder with no other cause)
SUnexplained piston failure on one cylinder (i.e. severe detonation, broken ring lands, piston holing)
SExcessive vibration of engine, backfiring, etc.
SRough idle, poor top speed.
CRANKSHAFT TRUING
Lubricate the bearings and clamp the crankshaft securely in the holding fixture. If truing the crankshaft requires striking with a
hammer, always be sure to re-check previously straightened areas to verify truing. Refer to the illustrations below. UseCrank-
shaft alignment kit PN 2870569.
NOTE:
The Rod Pin position in relation to the dial indicator tells you what action is required to straighten
the shaft.
To correct a situation like the one shown in illustration 1, strike the
shaft at point A with a brass hammer.
To correct a situation like the one shown in illustration 2, squeeze the
crankshaft at point A. you will use the tool from the alignment kit PN
2870569.
If the crank rod pin location is 180_from the dial indicator (opposite
that shown in illustrating 2), it will be necessary to spread the crank-
shaft at the A position as shown in illustration 3. When rebuilding and
straightening a crankshaft, straightness is of utmost importance. Run-
out must be as close to zero as possible.

OIL PUMP OPERATION AND TROUBLESHOOTING
BANJO TYPE
PRESS IN TYPE
Any time the engine is disassembled or repaired, itis important that the oil supply from the pump to
the engine be checked.
Banjo type or pressed in valves should open with 2 to 7 lbs. of pressure. Perform this test with 40:1
premix in the fuel tank.
Install new sealing washers upon installation on either side of the banjo check valve.
NOTE:
With engine in chassis, oil reservoir full, and pump bled, remove two oil feed line banjo bolts (A) from their location on the
manifold or carburetors.
Loosely thread the banjo bolts back into the manifold or carburetors.
Place oil feed lines with their check valves away from the clutch area.
Start the engine and let it idle at normal idle RPM.
Drops of oil should be visible from the banjo check valves after the engine is idled one to two minutes, with a drop occurring
approximately every few seconds
If oil does not flow from one of the check valves, remove oil line from check valve and again idle engine. If oil then flows, the
check valve is defective and must be replaced.
If oil does not flow with check valves removed from their feed lines, the malfunction is one of the following:
SInline filter blocked.
SAir not bled from oil pump.
SFeed lines leaking.
SOil tank vent restricted or kinked.
SDefective pump.

OIL PUMP BLEEDING
(A)
(A)
FUSION OIL PUMP
NOTE:
Any time the engine is disassembled or repaired,it is important that the oil supply from the pump
to the engine be checked.
IMPORTANT: The oil pump must always be bled following any service to the injector system or engine.
Fill oil reservoir with the appropriate Polaris injector oil. This will add pressure to the oil lines to aid in bleeding the air out.
Loosen bleed screw (A). After :30 seconds or so, oil should flow from beneath the screw head to indicate the pump is free of air.
Tighten bleed bleed screw securely.

OIL PUMP ADJUSTMENT PROCEDURE
.010-.030, (.25-.8 mm)
Throttle Freeplay
Figure 2
Figure 3
Figure 4
REQUIRED SERVICE:Carburetor synchronization.
VM TYPE:Verify that carburetor slides leave their respective resting positions uponopening within .01, to .03, of throttle cable
movement, not throttle lever movement. See figure 2.
TM TYPE:Verify that carburetor slidesare within .0625” of each other when passing the top of the carburetor throat. You may
have to move slides with the starter lever.
Adjust throttlecable freeplay to .010, - .030, (.25 - .8mm).
Set idle to specified idle speed listed in the specifications chapter.
Verify that the oil pump alignment lines are aligned at the point where the carburetor slides begin to raise from their resting posi-
tions. Note: Marks may not line up withoutthrottle engagement. See figure 3.
Make adjustments so that the lines are at the position shown in figure 4.
Torque cable locknuts to 10 - 20 in.lbs.
NOTE: Use a mirror when aligning the oil pump marks whenever the oil pump is difficult to view.
THROTTLE BODY TYPE (900)
All you need to do for the 900 oil pump is to verify that the oil pump marks line up (figure 4) when the throttle is in the idle position. You may need a mirror to see the marks straight on. If the line does not line up (figure 3) you will need to adjust the oil cable
at the throttle bell housing.
To adjust this loosen the lock nut and thread the barrel nut in or out depending on the direction you need the line to move.
Moving the barrel nut in will adjust the line more to the top.
DO NOT adjust the idle. This is all set at the factory and should not be tapered with.

COOLING SYSTEM OVERVIEW
DANGER
Never remove the pressure cap when the engine is warm or hot. If the pressure cap is to be removed,
the engine must be cool. Severe personal injury could result from steam or hot liquid.
Use of a non-standard pressure cap will not allow the recovery system to function properly.
If the cap should need replacement, install the correct Polaris cap with the same pressure rating.
Refer to the appropriate parts manual.
COOLANT LEVEL
Coolant level in the coolant bottle must be maintained between the MINIMUM and MAXIMUM levels to prevent overheating
and serious engine damage.
RECOMMENDED COOLANT
Use a 60/40 mixture of antifreeze and distilled water depending on the freezeprotection required for your area.
Do not use tap water in the system or reduced cooling or filter contamination may result.
Replace coolant every 2 years or if contaminated.
BLEEDING THE COOLING SYSTEM
Allow the system to cool completely.
Loosen the bleed screw and full the reservoir to the indicated Full Cold mark.
Once Full, tighten the bleed screw.
Apply parking brake and run the engine at specified idle RPM until the thermostat opens (approximately 5 to 8 minutes).
NOTE:
It is important that the thermostat stays open! When the thermostat opens it will draw in cold coolant
from the heat exchangers and the cold coolant may close the thermostat again. Make sure the thermo-
stat opens and stays open!Once the thermostat is open tip the snowmobile slightly on its right side.
Cycle the RPM from idle to enough RPM (4000) to get coolant to flow but not enough RPM to engage
the clutch. This allows air to bleed from the rear crossover tube. Then tilt the machine slightly on its
left side so that the coolant bottle is the highest point in the cooling system
. Cycle the RPM from idle to
enough RPM (4000) to get coolant to flow but not enough RPM to engage the clutch.It is important to
get enough coolant flow to purge the air from the front close-off cooler and observe this air reaching the
bottle.
Place the snowmobile in its normal riding position and loosen the bleed screw at the top of the water outlet manifold until trapped air
has been purged.
Tighten the bleed screw. Turn off the machine and release parking brake. Allow the system to cool completely. Re-check the cool-
ant level after the cap has been removed and add coolant to fill line if necessary. After the machine has cooled down, 3ounces
or more of coolant may have to beadded.
This procedure should take approximately 15 minutes.
NOTE:
It is important to get enough coolant flow to purge the air from the crossover hose or rear
cooler and observe this air reaching the bottle.
DANGER
When performing the following checks and adjustments, stay clear of all moving parts to avoid
serious personal injury.
Never remove the pressure cap when the engine is warm or hot. If the pressure cap is to be
removed, the engine must be cool. Severe personal injury could result from stream or hot liquid.

NOTE:
Do not operate a machine with the intake filters removed. This may cause carburetor icing
resulting poor fuel economy of carburetor malfunction.
The intake foam filter (A) limits snow ingestion into the intake system. When operating in loose powder, check the top of the
foam filter periodically to remove any accumulation of snow.
WATER / SEDIMENT TRAPDANGER
When draining the traps, fuel spillage will occur. be sure to work in a well ventilated area away
from anything which may cause the fuel to ignite such as an open flame, heaters, trouble lights or
cigarettes, certifying
Most Polaris snowmobiles incorporate a patented carburetor bowl water / sediment traps which are located at the bottom of each
carburetor. The trap consists of a hose with a plug which should be inspected for contamination every1000 miles (1600 km).
CLEANING PROCEDURE
Turn the fuel tank supply valve to the “OFF” position.
Position a container or shop towels under the work area to help catch
some of the contaminated gasoline.
Slide the clamp (A) away from the drain plug (B) and remove the drain
