To properly break in your Polaris RMK engine, operate the snowmobile at varying throttle positions, avoiding extended periods at full throttle, for the first 10 hours. This helps ensure proper engine seating and longevity.
Start by checking the battery charge and connections, ensuring the fuel is fresh, and inspecting the spark plugs for wear or damage. If issues persist, consult the user manual for further troubleshooting steps or contact a professional.
Regular maintenance includes checking the suspension for loose fasteners, inspecting the shocks and springs for wear, and lubricating all pivot points as specified in the owner’s manual.
To adjust track tension, lift the rear end of the snowmobile and support it securely. Loosen the rear axle bolts, turn the adjuster bolts evenly on both sides to achieve the correct tension, and then retighten the axle bolts. Refer to the manual for specific tension specifications.
Signs of a worn drive belt include fraying, cracking, or glazing on the belt surface, decreased performance, and unusual noises during operation. Regularly inspect the belt and replace it if any of these symptoms are present.
Improving fuel efficiency can be achieved by maintaining optimal tire pressure, using the recommended fuel type, reducing excess weight, and performing regular engine maintenance, such as changing spark plugs and air filters.
If overheating occurs, stop the engine immediately and let it cool down. Check the coolant level and look for any leaks or blockages in the cooling system. Ensure the radiator and cooling fins are clean and unobstructed.
It is recommended to change the oil every 1,000 miles or at the start of each season, whichever comes first. Regular oil changes help maintain engine performance and longevity.
For off-season storage, clean the snowmobile thoroughly, add a fuel stabilizer, change the oil, lubricate all moving parts, remove the battery and store it in a cool dry place, and cover the snowmobile to protect it from dust and moisture.
To replace the spark plugs, remove the spark plug cap, use a spark plug socket to unscrew the old spark plug, and install the new spark plug by hand to avoid cross-threading. Tighten to the specified torque and reattach the spark plug cap.
