Always wear safety glasses and nitrile gloves when servicing your Polaris snowmobile. To inspect and adjust the track tension on your Patriot Boost RMK Matryx Slash, follow these steps.

Track tension should be inspected and adjusted after every ride for the first 150 miles of use to ensure proper tension as the track stretches during break-in. After break-in, the tension should be inspected every 150 miles. Improper tension may result in damage to the suspension, track or driveshaft. Extreme vibration felt under hard acceleration or track loads indicates the tension should be inspected immediately, as continued use could result in permanent damage. 

1. Before beginning, ensure the track has been warmed up. 

2. Safely elevate the snowmobile. Refer to your Owner’s Manual for proper lifting techniques.

3. Begin by rotating the track by hand to check for damage. Carefully examine the track along the entire length of each rod. Bend the track to ensure there is no breakage.

4. If inspection reveals any concerns, see your authorized Polaris Dealer

5. Measure 16 inches ahead of the rear idler shaft on the track.

6. Apply 10 pounds of weight on the track, and measure the slack between the track and the rails. Reference your Owner’s Manual for track tension specifications. 

7. If the track requires adjustment, begin by loosening the rear idler shaft bolt with a 16mm socket, but do not remove.

8. Loosen the adjuster locknuts on both sides of the track with a 16mm wrench.

9. Tighten or loosen the track adjusting screws on both sides of the track with a 10mm socket to provide equal adjustment of the track tension.

10. After adjusting, tighten the locknuts until fully seated. 

11. Torque the idler shaft fastener to 33 ft-lbs (45 Nm).

12. Start the engine, and apply a small amount of throttle until the track turns slowly at least five complete revolutions. Stop the engine, and allow the track to come to a complete stop without applying the brakes.

13. Inspect the track alignment through the track windows in the rear to ensure the rails are evenly spaced on each side. 

14. If the track is offset to either side, loosen the adjustment nut on the side that the track is leaning toward, and tighten the adjusting screw as needed to gain alignment.

15. Start the engine again, and apply a small amount of throttle until the track turns slowly for at least five revolutions. Stop the engine, and allow the track to come to a complete stop without applying the brakes.

16. Reinspect the track alignment, and repeat this procedure as needed. 

17. Once complete, ensure all fasteners are tight, and safely lower the sled to the ground.
