VIDEO: ACE 150 Drive Chain Lubrication and Adjustment

Required tools

Always wear safety glasses and nitrile gloves when servicing your Polaris ACE. To lubricate and adjust the drive chain your ACE 150, follow these steps:

1. Park the vehicle on a flat, level surface and set the parking brake.

2. Using a 19mm socket, loosen the upper nut on the chain tensioner bracket.

3. Using a 12mm socket, loosen the front engine mount fastener to prevent the chain from binding during adjustment.

4. Then with an 8mm socket and 10mm socket, remove the drive chain cover fasteners. Carefully remove the cover.

5. Press down on the middle of the chain and measure the deflection. A new chain will stretch after the vehicle is used for a period of time. A new chain should measure 3/16 to 13/32 of an inch (5 to 10 mm). A broken-in chain should measure 13/32 to 19/32 of an inch (10 to 15 mm).

6. To adjust, use an 18mm wrench to turn the lower nut clockwise in half-turn increments.

7. Then tighten the upper nut until tight and recheck the deflection. Do not torque at this time.

8. Follow this procedure until the chain has proper deflection. Operating the vehicle with improper rear drive chain deflection can result in severe damage to the transmission and drive components.

9. Lubricate the drive chain with Polaris chain spray lube (part number 2872348) or an approved chain lube and use care to avoid spraying on the brakes. Do not use a high-pressure washer or gasoline to clean the drive chain.

10. Reinstall the drive chain cover and tighten the fasteners until fully seated.

11. Torque the engine mounting bolt to 37 ft-lbs (50 Nm). If needed, counter-hold the nut on the other end of the bolt.

12. Finish by torquing the upper chain tensioner bracket nut to 45 ft-lbs (61 Nm).
