MAINTENANCE
Special Tools
Special tools may be required while servicing this vehicle. Some of the tools listed or depicted are mandatory, while other tools maybe substituted with a similar tool, if available. Polaris recommends the use of Polaris Special Tools when servicing any Polaris product. Dealers may order special tools through Polaris’ official tool supplier, Bosch Automotive Service Solutions, by phone at 1-800-345-2233 or on-line at http://polaris.service-solutionsx.com/.
Overview
Careful periodic maintenance will help keep your vehicle in the safest, most reliable condition. 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 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.
• 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.
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 – If vehicle is subjected to severe use, decrease interval by 50% (Severe Use is defined as frequent vehicle immersion in mud, water or sand, racing or race-style high rpm use, prolonged low speed - heavy load operation or extended idle. More preventative maintenance is required under these conditions. Fluid changes, cable, chain and chassis lubrication are required more frequently. For engine oil, short trip cold weather riding also constitutes severe use. Pay special attention to oil level. A rising oil level in cold weather can indicate contaminants collecting in the oil sump or crankcase. Change oil immediately and monitor level. If oil level begins to rise, discontinue use and determine cause.)

MAINTENANCE
Engine Oil Level
The 800 EFI twin engine is a wet-sump engine, meaning the oil is contained in the bottom of the crankcase. To check the oil level:
1. Park machine on a level surface and set the parking brake.
2. Stop the engine. Allow the oil level to settle for 3 minutes before removing the dipstick.
NOTE: Do not check oil immediately after engine operation.
3. For easier access, remove the seat the RH side panel.
5. Reinstall dipstick and push it into place. Do not lock the dipstick.
NOTE: Make certain the dipstick is inserted all the way into the filler tube to keep the angle and depth of stick consistent. When reinstalling the dipstick, make certain to seat the lever lock.
6. Remove dipstick (C) and check to see that the oil level is in the normal range. Add oil as indicated by the level on the dipstick. Do not overfill. (See NOTE below!)
NOTE: Due to the dipstick entry angle into the crankcase, the oil level will read higher on the bottom side of the dipstick. Proper level indication is determined on the upper side of the dipstick as it is being removed, regardless of the level marks being on top or on bottom. (See illustration)
4. Unlock the lever lock (A). Remove dipstick (B) and wipe dry with a clean cloth.
2.10
9924864 - 2012-2014 SPORTSMAN 800 / 6X6

A rising oil level between checks in cool weather driving can indicate contaminants such as gas or moisture collecting in the crankcase. If the oil level is over the full mark, change the oil immediately.
MAINTENANCE
Oil/Filter Change
1. Park vehicle on a level surface.
2. Run engine two to three minutes until warm. Stop engine.
3. Clean area around drain plug at bottom of engine.

Ambient Temp Range: 0° F to 120° F
Capacity: 2 Quarts (1.9 L)
Oil Filter (PN 2540086)
13. Place gear selector in park and set the parking brake.
14. Start the engine and let it idle for one to two minutes. Stop the engine and inspect for leaks.
15. Re-check the oil level on the dipstick and add oil as necessary to bring the level to the upper mark on the dipstick.
16. Dispose of used filter and oil properly.

Compression Test
IMPORTANT: This engine does NOT have decompression components. Compression readings will vary in proportion to cranking speed during the test. Average compression (measured) is about 150­200 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

Cooling System
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.
• Some coolant level drop on new machines is
normal as the system is purging itself of trapped air. Observe coolant levels often during the break­in period.
• Overheating of engine could occur if air is not fully
purged from system.
• Polaris Premium 60/40 anti-freeze is premixed and
ready to use. Do not dilute with water.
Coolant Strength / Type
Test the strength of the coolant using an antifreeze hydrometer.
Cooling Hoses
Inspect all hoses for cracks, deterioration, abrasion or leaks. Replace if necessary.
• A 50/50 or 60/40 mixture of antifreeze and distilled
water will provide the optimum cooling, corrosion protection, and antifreeze protection.
• Do not use tap water, straight antifreeze, or
straight water in the system. Tap water contains minerals and impurities which build up in the system.
• Straight water or antifreeze may cause the system
to freeze, corrode, or overheat.

Tie Rod / Steering
• To check for play in the tie rod end, grasp the
steering tie rod, pull in all directions feeling for movement.
• Repeat inspection for inner tie rod end on steering
post.
• 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.
• If abnormal movement is detected, inspect the hub and wheel assembly to determine the cause (possible loose wheel nuts or loose front hub components).

Wheel Alignment
1. Place machine on a smooth level surface.
2. Set handlebars in a straight ahead position and secure handlebars in this position.
3. 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.
NOTE: It is important that the height of both marks be equally positioned in order to get an accurate measurement.
4. Measure the distance between the marks and record the measurement. Call this measurement “A”.
5. Rotate the tires 180° by moving vehicle forward or backward. Position chalk marks facing rearward, even with the hub/axle centerline.
6. 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).
Toe Alignment
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 handlebars are 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.
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. See illustration.
• After alignment is complete, torque jam nuts to specification.

Recommended Coolant
Use only high quality antifreeze/coolant mixed with distilled water in a 50/50 or 60/40 ratio, depending on freeze protection required in your area. CAUTION: Using tap water in the cooling system will lead to a buildup of deposits which may restrict coolant flow and reduce heat dissipation, resulting in possible engine damage. Polaris Premium 60/40 Antifreeze/Coolant is recommended for use in all cooling systems and comes pre-mixed, ready to use.

Cooling System Pressure Test
WARNING
Never remove filler cap when engine is warm or hot.
The cooling system is under pressure and serious
burns may result. Allow the engine and cooling system
to cool before servicing.
System Pressure Test
1. Remove radiator cap cover located under the storage box access panel. See Chapter 5.
2. Remove recovery bottle hose from coolant filler.
3. Connect a Mity Vac™ (PN 2870975) to radiator and pressurize system to 10 PSI (68.9 kpa). The system must retain 10 lbs of pressure for five minutes or longer. If pressure loss is evident within five minutes, check radiator, all cooling system hoses and clamps, or water pump seal.
Filler Cap Pressure Test
4. Remove filler cap and test cap using a commercially available cap tester.
5. The filler cap relief pressure is 13 psi. Replace cap if it does not meet this specification.
Coolant Air Bleeding Procedure
Use this procedure when a unit overheats and no apparent leaks in the cooling system are found.
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.
1. Park machine on a flat surface. Remove filler cap and top off coolant. With the cap removed, start and idle machine for 5-10 minutes until steam is visible in the filler neck area.
2. Stop the engine and let cool for a few minutes or until an air bubble is seen at the filler neck, or there is a dropping of the coolant level indicating that coolant has been pulled into the system.
NOTE: Slowly squeezing the filler neck/coolant return hoses will aid in purging the system of air. Pump the hose using your hand several times. Elevating the rear of the ATV with a floor jack (rear tires 4-6”, off the ground) also aids the purging of air from the system.
3. Repeat Steps 1 and 2 until no more coolant is pulled into the system.
4. To test, install the radiator cap and idle machine until fan comes on. Make sure the fan comes on before the hot light.

3.19
ENGINE
13. Start engine and observe coolant level in the radiator. Allow air to purge and top off as necessary. Reinstall radiator cap and bring engine to operating temperature. After engine is cool, check level in reservoir tank and add coolant if necessary.
NOTE: Should the reservoir tank become empty, it will be necessary to refill at the radiator and repeat the bleeding procedure.
Engine Break-In Period
The break-in period for a Polaris ATV engine is defined as the first ten hours of operation, or the time it takes to use two full tanks of gasoline. No single action on your part is as important as a proper break­in period. Careful treatment of a new engine will result in more efficient performance and longer life for the engine. Perform the following procedures carefully.
CAUTION
Use only Polaris PS4 2W/50 synthetic oil or equivalent.
Never substitute or mix oil brands. Serious engine
damage and voiding of warranty can result.
Do not operate at full throttle or high speeds for
extended periods during the first three hours of use.
Excessive heat can build up and cause damage to
close fitted engine parts.
Cylinder Hone Selection And Honing Procedure
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.
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.
14. Fill fuel tank with unleaded or leaded fuel which has a minimum pump octane number of 87= (R+ M)/2.
15. Check oil reservoir level indicated on dipstick. Add oil if necessary (Refer to Chapter 2, “Engine Oil Level” ).
16. Drive slowly at first to gradually bring engine up to operating temperature.
17. Vary throttle positions. Do not operate at sustained idle or sustained high speed.
18. Perform regular checks on fluid levels, controls and all important bolt torques. Pull only light loads during initial break in.
19. Pull only light loads during initial break-in.
20. Change break in oil and filter at 20 hours or 200 miles.

ENGINE
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.
• Release the hone at regular intervals and inspect the bore to determine if it has been sufficiently de­glazed, 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.
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. Use electrical contact cleaner if necessary to clean these areas. Rinse thoroughly, dry with compressed air, and oil the bore immediately with Polaris Lubricant.

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.

Oil Flow Chart
This chart describes the flow of oil through the 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.

head disassembly and reassembly.
WARNING
ENGINE
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, and 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.
1. Install pilot into valve guide.
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° and make another light cut.
* 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°) apply black permanent marker to the entire valve face (A).
3
2. Apply cutting oil to valve seat and cutter.
3. Place 46° cutter on the pilot and make a light cut.

6. Insert valve into guide and tap valve lightly into place a few times.
3.31
ENGINE
7. Remove valve and check where the Prussian Blueä indicates seat contact on the valve face. The valve seat should contact the middle of the valve face or slightly above, and must be the proper width.
* If the indicated seat contact is at the top edge of the valve face and contacts the margin area (B) it is too high on the valve face. Use the 30° cutter to lower the valve seat.
* If too low, use the 60° cutter to raise the seat. When contact area is centered on the valve face, measure seat width.
* If the seat is too wide or uneven, use both top and bottom cutters to narrow the seat.
* If the seat is too narrow, widen using the 45° cutter and re-check contact point on the valve face and seat width after each cut.
NOTE: When using an interference angle, the seat contact point on the valve will be very narrow, and is a normal condition. Look for an even and continuous contact point all the way around the valve face. (B)
Valve Seat Width:
Intake
Std: .028" (.7 mm)
Limit: .055" (1.4 mm)
Exhaust
