ABDC: After bottom dead center. ACV: Alternating current voltage. Alternator: Electrical generator producing voltage alternating current. ATDC: After top dead center. BBDC: Before bottom dead center. BDC: Bottom dead center. BTDC: Before top dead center. CC: Cubic centimeters. Center Distance: Distance between center of crankshaft and center of driven clutch shaft. Chain Pitch: Distance between chain link pins (No. 35 = 3/8" or 1 cm). Polaris measures chain length in number of pitches. CI: Cubic inches. Clutch Buttons: Plastic bushings which aid rotation of the movable sheave in the drive and driven clutch. Clutch Offset: Drive and driven clutches are offset so that drive belt will stay nearly straight as it moves along the clutch face. Clutch Weights: Three levers in the drive clutch which relative to their weight, profile and engine RPM cause the drive clutch to
close and grip the drive belt. Crankshaft Run-Out: Run-out or "bend" of crankshaft measured with a dial indicator while crankshaft is supported between centers on V blocks or resting in crankcase. Measure at various points especially at PTO.
DCV: Direct current voltage CVT: Centrifugal Variable Transmission (Drive Clutch System) DCV: Direct current voltage. Dial Bore Gauge: A cylinder measuring instrument which uses a dial indicator. Good for showing taper and out-of-round in t he
cylinder bore.
Electrical Open: Open circuit. An electrical circuit which isn't complete. Electrical Short: Short circuit. An electrical circuit which is completed before the current reaches the intended load. (i.e. a bare wire
touching the chassis).
End Seals: Rubber seals at each end of the crankshaft. Engagement RPM: Engine RPM at which the drive clutch engages to make contact with the drive belt. ft.: Foot/feet. Foot Pound: Ft. lb. A force of one pound at the end of a lever one foot in length, applied in a rotational direction. g: Gram. Unit of weight in the metric system. gal.: Gallon. ID: Inside diameter. in.: Inch/inches. Inch Pound: In. lb. 12 in. lbs. = 1 ft. lb. kg/cm²: Kilograms per square centimeter. kg-m: Kilogram meters. Kilogram/meter: A force of one kilogram at the end of a lever one meter in length, applied in a rotational direction. l or ltr: Liter. lbs/in²: Pounds per square inch. Left or Right Side: Always referred to based on normal operating posit ion of the driver. m: Meter/meters. Mag: Magneto. Magnetic Induction: As a conductor (coil) is moved through a magnetic field, a voltage will be generated in the windings.
Mechanical energy is converted to electrical energy in the stator.
mi.: Mile/miles. mm: Millimeter. Unit of length in the metric system. 1 mm = approximately .040". Nm: Newton meters. OD: Outside diameter. Ohm: The unit of electrical resistance opposing current flow. oz.: Ounce/ounces. Piston Clearance: Total distance between piston and cylinder wall. psi.: Pounds per square inch. PTO: Power take off. PVT: Polaris Variable Transmission (Drive Clutch system) qt.: Quart/quarts. Regulator: Voltage regulator. Regulates battery charging system output at approx. 14.5 DCV as engine RPM increases. Reservoir Tank: The fill tank in the liquid cooling system. Resistance: In the mechanical sense, friction or load. In the electrical sense, ohms, resulting in energy conversion to heat. RPM: Revolutions per minute. Seized Piston: Galling of the sides of a piston. Usually there is a transfer of aluminum from the piston onto the cylinder wall. Possible causes: 1) improper lubrication; 2) excessive temperatures; 3) insufficient piston clearance; 4) stuck piston rings. Stator Plate: The plate mounted under the flywheel supporting the battery charging coils. TDC: Top dead center. Piston's most outward travel from crankshaft. Volt: The unit of measure for electrical pressure of electromotive force. Measured by a voltmeter in parallel with the circuit. Watt: Unit of electrical power. Watts = amperes x volts. WOT: Wide open throttle.

MAINTENANCE
PERIODIC MAINTENANCE CHART
Periodic Maintenance Overview
Inspection, adjustment and lubrication of important components are explained in the periodic maintenance chart. Inspect, clean, lubricate, adjust and replace parts as necessary. When inspection reveals the need for replacement parts, use
genuine Pure Polaris parts available from your Polaris dealer.
NOTE: Service and adjustments are critical. If you’re not familiar with safe service and adjustment procedures, have a qualified dealer perform these operations.
Maintenance intervals in the following chart are based upon average riding conditions and an average vehicle speed of approximately 10 miles per hour. Vehicles subjected to severe use must be inspected and serviced more frequently.
Severe Use Definition
• Frequent immersion in mud, water or sand
• Racing or race-style high RPM use
• Prolonged low speed, heavy load operation
• Extended idle
• Short trip cold weather operation
2
Pay special attention to the oil level. A rise in oil level during cold weather can indicate contaminants collecting in the oil sump or crankcase. Change oil immediately if the oil level begins to rise. Monitor the oil level, and if it continues to rise, discontinue use and determine the cause or see your dealer.
Break-In Period
The break-in period consists of the first 25 hours of operation, or the time it takes to use 14 gallons (53 liters) of fuel. Careful treatment of a new engine and drive components will result in more efficient performance and longer life for these components.
• Drive vehicle slowly at first while varying the throttle position. Do not operate at sustained idle.
• Pull only light loads.
• Perform regular checks on fluid levels and other areas outlined on the daily pre-ride inspection checklist.
• Change both the engine oil and filter after 25 hours or one month.
• See “Owner’s Manual” for additional break-in information.
Maintenance Chart Key
The following symbols denote potential items to be aware of during maintenance:
= CAUTION: Due to the nature of these adjustments, it is recommended this service be performed by an authorized Polaris dealer.
= SEVERE USE ITEM: See information provided above.
E = Emission Control System Service (California). NOTE: Inspection may reveal the need for replacement parts. Always use genuine Polaris parts.

ENGINE
Compression and Leakdown Test
NOTE: This engine does NOT have decompression components. Compression readings will vary in proportion to cranking speed during the test. Average compression (measured) is about 150-200 psi during a compression test.
A smooth idle generally indicates good compression. Low engine compression is rarely a factor in running condition problems above idle speed. Abnormally high compression can be caused by carbon deposits in the combustion chamber or worn, damaged exhaust cam lobes. Inspect camshaft and combustion chamber if compression is abnormally high.
A cylinder leakdown test is the best indication of engine condition. Follow manufacturer's instructions to perform a cylinder leakage test (never use high pressure leakage testers, as crankshaft seals may dislodge and leak).
Cylinder Compression
Standard: 150-200 PSI
Cylinder Leakdown
Service Limit 15%
Engine Oil Level
The twin cylinder engine is a wet-sump engine, meaning the oil is contained in the bottom of the crankcase. To check the oil level follow the procedure listed below.

COOLING SYSTEM
Coolant Level Inspection
The recovery bottle, located on the left side of the machine, must be maintained between the minimum and maximum levels indicated on the recovery bottle.
Surge Tank Cap
With the engine at operating temperature, the coolant level should be between the upper and lower marks on the coolant reservoir. If not:
1. Remove reservoir cap. Inner splash cap vent hole must be clear and open.
2. Fill reservoir to upper mark with Polaris Premium 60/40 Anti Freeze / Coolant or 50/50 or 60/40 mixture of antifreeze and distilled water as required for freeze protection in your area.
Liquid Cooling System Overview
The engine coolant level is controlled or maintained by the recovery system. The recovery system components are the recovery bottle, radiator filler neck, radiator pressure cap and connecting hose.
As coolant operating temperature increases, the expanding (heated) excess coolant is forced out of the radiator past the pressure cap and into the recovery bottle. As engine coolant temperature decreases the contracting (cooled) coolant is drawn back up from the tank past the pressure cap and into the radiator.
NOTE: Some coolant level drop on new machines is normal as the system is purging itself of trapped air. Observe coolant levels often during the break-in period.
Overheating of engine could occur if air is not fully purged from system.
Polaris Premium 60/40 is already premixed and ready to use. Do not dilute with water.
3. Reinstall cap.

Battery Charging
1. Remove the battery from the vehicle to prevent damage from leaking or spilled electrolyte during charging.
2. Charge the battery with a charging output no larger than 1/10 of the battery’s amp/hr rating. Charge as needed to raise the specific gravity to 1.270 or greater.
3. Reinstall the battery.
To reduce the chance of sparks: Whenever
removing the battery, disconnect the negative
(black) cable first. When reinstalling the battery,
install the negative cable last.

MAINTENANCE
STEERING AND SUSPENSION
Steering
The steering components should be checked periodically for loose fasteners, worn tie rod ends, and damage. Also check to make sure all cotter pins are in place. If cotter pins are removed, they must not be re-used. Always use new cotter pins.
Replace any worn or damaged steering components. Steering should move freely through entire range of travel without binding. Check routing of all cables, hoses, and wiring t o be sure the steering mechanism is not restricted or limited.
NOTE: Whenever steering components are replaced, check front end alignment.
WARNING
Due to the critical nature of the procedures
outlined in this chapter, Polaris recommends
steering component repair and adjustment be
performed by an authorized Polaris MSD-
certified technician when replacing worn or
damaged steering parts.
Use only genuine Polaris replacement parts.
• If abnormal movement is detected, inspect the hub and wheel assembly to determine the cause (loose wheel nuts or loose front hub nut).
• Refer to the Final Drive chapter for more information.
Wheel Toe Alignment Inspection

1. Place machine on a smooth level surface and set steering wheel in a straight ahead position. Secure the steering wheel in this position.
2. Place a chalk mark on the center line of the front tires approximately 10” (25.4 cm) from the floor or as close to the hub/axle center line as possible.
Measure Here
Mark (A), measure, then roll forward and measure (B).
Tie Rod End / Steering Inspection
• To check for play in the tie rod end, grasp the steering tie rod, pull in all directions feeling for movement.
• Replace any worn steering components. Steering should move freely through entire range of travel without binding.
• Elevate front end of machine so front wheels are off the ground. Check for any looseness in front hub / wheel assembly by grasping the tire firmly at top and bottom first, and then at front and rear. Try to move the wheel and hub by pushing inward and pulling outward.
A
10”
NOTE: It is important the height of both marks be equally positioned to get an accurate measurement.
3. Measure the distance between the marks and record the measurement. Call this measurement “A”.
4. Rotate the tires 180 Position chalk marks facing rearward, even with the hub/ axle center line.
5. Again measure the distance between the marks and record. Call this measurement “B”. Subtract measurement “B” from measurement “A”. The difference between measurements “A” and “B” is the vehicle toe alignment. The recommended vehicle toe tolerance is 1/8”, to 1/4”, (.3 to .6 cm) toe out. This means the measurement at the front of the tire (A) is 1/8”, to 1/4”, (.3 to .6 cm) wider than the measurement at the rear (B).

MAINTENANCE
Toe Adjustment
If toe alignment is incorrect, measure the distance between vehicle center and each wheel. This will tell you which tie rod needs adjusting.
NOTE: Be sure steering wheel is straight ahead before determining which tie rod(s) need adjustment.
CAUTION
During tie rod adjustment, it is very important that
the following precautions be taken when
tightening tie rod end jam nuts.
If the rod end is positioned incorrectly it will not
pivot, and may break.
To adjust toe alignment:
• Hold tie rod end to keep it from rotating.
• Loosen jam nuts at both end of the tie rod.
• Shorten or lengthen the tie rod until alignment is as required to achieve the proper toe setting as specified in “Wheel Toe Alignment”.
Front Suspension
• Compress and release front suspension. Damping should be smooth throughout the range of travel.
• Check all front suspension components and fasteners for wear or damage.
• Inspect front strut cartridges for leakage.
Bolt Torque
15 ft. lbs. (20 Nm)
Inspect for leaks
IMPORTANT: When tightening the tie rod end jam
nuts, the rod ends must be held parallel to prevent rod end damage and premature wear. Damage may not be immediately apparent if done incorrectly.

BRAKE SYSTEM
Brake Fluid Inspection
Always check the brake pedal travel and inspect the brake fluid reservoir level before each operation. If the fluid level is low, add DOT 4 brake fluid only.
Brake fluid should be changed every two years. The fluid should also be changed anytime the fluid becomes contaminated, the fluid level is below the minimum level, or if the type and brand of the fluid in the reservoir is unknown.
The brake fluid master cylinder reservoir can be accessed by lifting up the front hood.
1. Position the vehicle on a level surface.
2. Place the transmission in Neutral (N) and set the parking brake.
3. View the brake fluid level in the reservoir. The level should be between the MAX and MIN level lines.
4. If the fluid level is lower than the MIN level line, add brake fluid until it reaches the MAX level line.
Brake Pad / Disc Inspection
1. Check the brake pads for wear, damage, or looseness.
2. Inspect the brake pad wear surface for excessive wear.
3. Pads should be changed when the friction material is worn to .040” (1 mm).
Measure Pad Material
Thickness
4. Check surface condition of the brake discs.
5. Measure the thickness of the front and rear brake discs.
Service Limit:
.040" (1 mm)
5. Install the reservoir cap and apply the brake pedal forcefully for a few seconds and check for fluid leakage around the master cylinder fittings and the brake caliper fittings.
Maximum
Minimum
Brake Hose and Fitting Inspection
Check brake system hoses and fittings for cracks, deterioration, abrasion, and leaks. Tighten any loose fittings and replace any worn or damaged parts.
6. The disc(s) should be replaced if thickness is less than the specified service limit (see Chapter 9 for specifications).
Measure Brake Disc Thickness

Parking Brake Cable Adjustment
When the parking brake is fully engaged and the parking brake indicator is illuminated, engine speed is limited to 1300 RPM in all gears, including neutral. If throttle is applied, this l imiting feature prevents operation, which protects the parking brake pads from excessive wear.
NOTE: Inspect the parking brake cable tension after the first 25 hours of operation and every 100 hours of operation afterwards to ensure proper cable tension.
2.32
Loss of tension in the parking brake cable will cause illumination of the parking brake light and activation of the limiting feature. If this occurs, inspect and adjust parking brake cable tension. If performing this service is difficult due to conditions or location, open the hood and temporarily disconnect the parking brake connector. Reconnect the connector as soon as practicable and adjust the parking brake cable to proper tension.
1. Pull back on the parking brake lever (located in the dash).
2. After 2 to 3 clicks the “(P)” brake light should illuminate on the instrument cluster and the wheels of the vehicle should not rotate when turning by hand. After 8 full clicks of lever travel, the vehicle should not roll while parked.
3. If the vehicle moves, adjustment is necessary.
4. Adjust the parking brake cable where the cable attaches to the caliper mount bracket located on the rear gearcase.
Adjustment Procedure: Refer to “Chapte r 9 - Brakes” for complete adjustment procedure.

Cooling System Bleeding Procedure
WARNING
Always wear safety glasses and proper shop
clothing when performing the procedures in this
manual. Failing to do so may lead to possible
injury or death.
CAUTION
Use caution when performing these procedures.
Coolant may be hot and may cause
severe injury or burns.
NOTE: If the coolant level is LOW in the radiator, or if there are leaks in the system, the coolant system will not draw coolant from the reservoir tank.
NOTE: Use this procedure when a unit overheats and no apparent leaks in the cooling system are found.
1. Place the vehicle in Neutral and set the parking brake.
CAUTION
Be sure the engine has cooled and there is no
pressure built up in the cooling system before
removing the radiator cap. The coolant may be
hot and could cause severe injury or burns.
2. Remove radiator cap (A) and top off coolant.
3. Remove surge tank fill cap (B) and fill the surge tank to the full line.

4. Elevate the driver’s side of the vehicle 20” (50.8 cm) off the ground so the thermostat housing is at the highest point on the cylinder head. This will allow any trapped air to accumulate near the thermostat housing bleed screw.
CAUTION
Serious injury may result if machine tips or falls. Be sure machine is secure before beginning this
service procedure.
8. Add Polaris Premium Antifreeze to the radiator if the level goes down.
9. Tighten the bleed screw to 70 ± 10 in.lbs. (8 ± 1.13 Nm) on the thermostat housing and properly install the radiator cap.
WARNING
Be sure to install the radiator cap before
shutting off the engine.
Coolant may spit out of the radiator.
10. Stop the engine and let cool, top off the radiator filler neck with coolant. If you hear or see a “glug” at the filler neck or there is a dropping of the coolant level, indicating that coolant has been pulled into the system. Fill the surge tank only after you have completely filled the cooling system at the radiator filler neck.
11. Repeat this procedure, if overheating still occurs.
20” (50.8 cm)
5. Start the engine and let it idle for 5-10 minutes or until the thermostat opens and allows coolant to flow through the system.
6. Squeeze the coolant lines by hand to help purge the system of air.
7. Slightly loosen the bleed screw (C) on the thermostat housing to allow the trapped air to escape. If no air is present, a steady stream of coolant will stream out. If air is present, the screw will bubble and sputter as the air escapes.

ENGINE
Oil Flow Chart
This chart describes the flow of oil through the 700 engine. Beginning in the crankcase sump, the oil is drawn through an oil galley to the feed side of the oil pump. The oil is then pumped through the oil filter. If the oil filter is obstructed, a bypass valve contained in the filter allows oil to bypass the filter element. At this point, the oil is supplied to the main oil galley through a crankcase passage. Oil is then diverted three ways from the main oil galley, with the first path entering the camshaft bores, onto the rear balance shaft journal and then draining back into the crankcase sump. The second oil path from the main oil galley feeds the lifter bores and then drains back to the crankcase sump. The third oil path flows through a crankcase galley to the MAG side crankshaft journal and also
to the front balance shaft journal and onto the crankcase sump. The oil pressure switch is fed off the main oil galley.

Combustion Chamber
1. Clean all accumulated carbon deposits from combustion chamber and valve seat area with carbon cleaner and a soft plastic scraper.
IMPORTANT: Do not use a wire brush, metal scraper, or abrasive cleaners to clean the bottom of the cylinder head. Extensive damage to the cy linder head may result. Wear safety glasses during cleaning.
Combustion Area
NOTE: Valve seat width and point of contact on the valve face is very important for proper sealing. The valve must contact the valve seat over the entire circumference of the seat, a nd the seat must be the proper width all the way around. If the seat is uneven, compression leakage will result. If the seat is too wide, seat pressure is reduced, causing carbon accumulation and possible compression loss. If the seat is too narrow, heat transfer from valve to seat is reduced. The valve may overheat and warp, resulting in burnt valves.

Valve Seat Inspection
Inspect valve seat in cylinder head for pitting, burnt spots, roughness, and uneven surface. If any of the above conditions exist, the valve seat must be reconditioned. If the valve seat is
cracked the cylinder head must be replaced.
Follow the manufacturers instructions provided with the valve seat cutters in the Cylinder Head Reconditioning Kit (PN
2200634). Abrasive stone seat reconditioning equipment can
also be used. Keep all valves in order with their respective seat.

4. Inspect the cut area of the seat: * If the contact area is less than 75% of the circumference of the
seat, rotate the pilot 180
* If the cutter now contacts the uncut portion of the seat, check the pilot. Look for burrs, nicks, or runout. If the pilot is bent it must be replaced.
* If the contact area of the cutter is in the same place, the valve guide is distorted from improper installation
* If the contact area of the initial cut is greater than 75%, continue to cut the seat until all pits are removed and a new seat surface is evident. NOTE: Remove only the amount of material necessary to repair the seat surface.
5. To check the contact area of the seat on the valve face, apply a thin coating of Prussian Blue paste to the valve seat. If using an interference angle (46 marker to the entire valve face (A).

Cylinder Hone Selection And Honing Procedure
Cylinders may be wet or dry honed depending upon the hone manufacturer’s recommendations. Wet honing removes more
material faster and leaves a more distinct pattern in the bore.
CAUTION
A hone which will straighten as well as remove
material from the cylinder is very important.
Using a common spring loaded glaze breaker
for honing is not advised for nicasil cylinders.
Polaris recommends using a rigid hone or arbor
honing machine. Cylinders may be wet or dry
honed depending upon the hone manufacturer's
recommendations.
Wet honing removes more material faster and
leaves a more distinct pattern in the bore.
Honing To Deglaze
A finished cylinder should have a cross-hatch pattern to ensure piston ring seating and to aid in the retention of the fuel/oil mixture during initial break in. Hone cylinder according to hone manufacturer's instructions, or these guidelines:
• Honing should be done with a diamond hone. Cylinder could be damaged if the hone is not hard enough to scratch the nicasil lining.
• Use a motor speed of approximately 300-500 RPM, run the hone in and out of the cylinder rapidly until cutting tension decreases. Remember to keep the hone drive shaft centered (or cylinder centered on arbor) and to bring the stones approximately 1/2, (1.3 cm) above and below the bore at the end of each stroke.
If cylinder wear or damage is excessive, it will be necessary to replace the cylinder. The cylinders are lined with a nicasil coating and are not repairable. Hone only enough to de-glaze the outer layer of the cylinder bore.
3
Example of Cross Hatch Pattern
IMPORTANT: Clean the cylinder after honing
If cylinder wear or damage is excessive, it will be necessary to replace the cylinder. The cylinders are lined with a nicasil coating and are not repairable. Hone only enough to de-glaze the outer layer of the cylinder bore.
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 immediately with Polaris Lubricant.
• Release the hone at regular intervals and inspect the bore to determine if it has been sufficiently de-glazed, and to check for correct cross-hatch.
NOTE: Do not allow cylinder to heat up during honing.
• After honing has been completed, inspect cylinder for thinning or peeling.
