Send yours to Tom Morgan Racing for a new bushing.
All you will likely find on the used market is the same worn out part you already own.
The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

Hello,
What are the tolerances on this bush please. Mine too has a lot of play. I can make one and fit it. I guess the question is how much wobble should there be, or should it be a wobble free spin fit ?
Thanks all

None are published that I am aware of.
I measure the shaft and use +.001/-.000

Hey guys so I sent my gears to Tom Morgan to get a bushing machined. The 1990 gear was quite wobbly and the 1988 I have was really bad
