Step by Step Guide of Harley Davidson Compensator Replacement

  • Choose a location with adequate space: Ensure you choose an area or location with enough space that can accommodate your bike. Your location choice must allow unrestricted movement. It must also guarantee safe storage of removed parts and components to prevent loss.
  • Leave the engine to cool off: Don’t conduct a replacement immediately you turn off the engine, or bring the bike to a halt. Give the bike a few minutes to cool off before you start working on it.
  • Detach the heel shifter and left footboard: Before you can replace or upgrade your compensator, you will have to disassemble it from the bike. The first step is to take off the motorcycle’s left footboard and heel shifter. While trying to remove these parts, do it carefully.
  • Drain the primary drive oil and take out the primary cover: The oil in the primary drive must be drained. While removing the primary cover, ensure you take your time. You have to be careful with it, and don’t rush.

Usually, the inner primary and drive assembly will let out residual oil. You can prevent this oil from spilling over the ground or garage’s surface using a baking tray.

  • Check for wears: Immediately the oil drain plug and primary cover are removed, the compensator becomes visible. At this stage, the wear marks on the sprocket become visible and easily noticeable.
  • Take out the clutch hub snap ring: To successfully remove this part, you need a plier (19-66mm). If you find it hard or challenging to remove the clutch hub snap ring using a plier. In that case, you can pull the clutch plate apart.

Since the clutch hub main shaft comes with a 30mm hex head, a primary drive locking tool is required to complete this operation successfully.

  • Detach the compensator: You need to unscrew or detach the compensator from your Harley as a single unit using a T-70 Torx bit.

For easy removal, the compensator bolts should be heated with a MAPP gas torch. When you heat the bolt, the Loctite patch that was applied to the threads of the compensator bolt from the factory is softened and weakened.

  • Clean the sprocket shaft threads: There are various approaches or techniques that you can adopt. You can make use of a 9/16-12 tap, or brake cleaner and compressed air. You need to be very careful if you are making use of the former technique (the tap). Take your time. Ensure you are not damaging the shaft threads while cleaning or taking off the residual Loctite.
  • Replace the compensator: Immediately after the old/damaged unit has been removed, the next step is to replace it with the new compensator. The compensator kit comes with all the necessary hardware. Ensure you couple all of these drive components accordingly before the final installation on the bike.
  • Apply Red Loctite 262: Add a few drops of this solution (Red Loctite) on the clutch hub snap ring. Once the application is complete, reinstall/reattach it back to its position on the bike. Ensure it is rightly placed and everything is accurate.
  • Install a new gasket: Once the snap ring and release plate are positioned or placed in their various compartments, then you need to pull the chain tensioner together. Afterward, install a new gasket and secure it properly.
  • Assemble the primary housing: The next stage is to pull the primary housing back together. Also, ensure you fill/apply clean and clear lubricant into the primary chain case. The lubricant must be sufficient enough (it must get to the clutch’s bottom).
  • Conduct final inspection: Now that you have successfully completed the replacement exercise, do not forget to inspect each and every part. The final inspection ensures you do not miss any step of the replacement process. It also guarantees that everything is in place, and the task is executed accurately.
