Before you ride your Polaris 550 INDY 121, 550 INDY 144 and 550 INDY Sport snowmobiles, perform the pre-ride inspection as described in your Owner’s Manual.
Warning: Read, understand and follow all of the instructions, warnings and safety precautions in the Owner’s Manual and on all product labels. Failure to follow these instructions, warnings and safety precautions could result in serious injury or death.
When performing your pre-ride inspection, do the following:
1. Visually inspect the vehicle, looking for debris, leaks and worn components that may impair the vehicle’s operation.
2. Remove both front side panels by releasing the rubber strap and turning the two latches on each side. Pull the panel out and lift up to remove from the vehicle.
3. Starting on the left side of the sled, inspect the condition of the drive belt, looking for any looseness, fraying, missing cogs, burns, abrasions or damage.
4. Move over to the right side of the sled and inspect the injection oil level in the oil tank. Add oil as needed.
5. Then inspect the brake pads and rotor for any corrosion, nicks or burrs.
6. Clean the area around the chaincase fill plug and remove it with a 6mm Allen socket.
7. Ensure the fluid is level with the bottom of the threads. Add fluid as needed.
8. Reinstall the chaincase fill plug. Torque to 6-10 ft-lbs (8-13 Nm).
9. Reinstall both side panels by aligning the tabs at the bottom and top. Then secure the rubber straps and latches.
10. Move to the front suspension and inspect for fastener tightness on the shock assembly, control arms, tie rods and spindle.
11. Then inspect for leaks and damage.
12. Inspect the skis for any damage or wear and replace if necessary.
13. Lift up on the skis and inspect the skags for wear.
Warning: Worn skags may adversely affect handling causing loss of control and serious injury or death. See your dealer's studding chart for recommended skags.
14. Next, safely elevate the snowmobile per the Owner’s Manual guidelines to inspect the rear suspension.
15. Inspect the front torque arm limiter strap for wear or damage. Replace if necessary.
16. Continue by inspecting the rail slides for wear. Replace if worn to the wear limit indicator groove.
17. Measure the track tension per the Owner's Manual guidelines and adjust as necessary.
Notice: Tension adjustments should only be made after the track has been warmed up.
18. Next, inspect the track for proper alignment by looking through the track windows in the rear. Ensure they are evenly spaced apart and adjust as necessary.
19. Continue by inspecting the rear idler wheel bolt and adjusting bolt locknuts for tightness.
20. Safely lower the vehicle to the ground after completing the rear suspension inspection.
21. Next, ensure smooth operation of the steering system by turning the skis from full left to full right.
22. Slowly pull the recoil rope out and inspect the handle and rope for any excessive wear.
23. Ensure proper fluid level in the brake fluid reservoir.
Tip: Use a flashlight to illuminate the brake fluid reservoir.
24. Operate the brake and throttle levers, taking note of any binding or sticking.
25. Ensure proper operation of the parking brake.
26. Start the engine and ensure there are no warning lights present.
27. Next, inspect the headlights, taillight and brake light for proper operation.
28. Push the engine stop switch to stop the engine. Ensure it does not restart.
29. Restart the engine and ensure the engine turns off when the ignition switch is turned off.
