Cush Drive Bushing Replacement

 

In this video tutorial I demonstrate how to remove and replace the cush drive bushings located in the rear hub of your motorcycle rim.

The cush bushings are just one of those maintenance parts you never knew existed until you experience an issue with a slapping sound coming from the rear hub during quick accelerations or engagement of the rear drive train.

As the name implies the job or function of these thick rubber pieces is to cushion the impact or engagement torq translated from the chain and sprocket to the rear wheel hub. Without them, engagement is very much harsh sounding and most often describe as a knock or slap of metal upon metal which the feeling can be translated throughout the bike.

I first came to realize that I had an issue with my cush drives during takeoff or quick accelerations from a dead stop. Later, as the cush dives became extremely worn this issue became more pronounced during slow rolling takeoff and I also began to experience the sound and slap sensation during shifts.

This issue had me scratching my head for some time because it's rare that one would ever experience this issue unless they for one, had there bike for an extremely long time with high mileage, or two, do some really hard riding such as quarter mile or track racing. In my case I was the second owner and purchased my bike at 38k miles. At the time of replacement I had already put another 40k on the clock.

In any case, if your experiencing the sound or feeling a knocking or slapping sensation from your rear tire during takeoff, quick acceleration or down shifting then chances are this is your issue and this video is for you.
