I recently pulled the pilot bushing and regretted it. It wouldn't come out with all the regular tricks and when it finally did it was in pieces. It had a waffle pattern on it
and looks like it left some of it inside the crank as well.
I have a new bushing to install and I'm looking for the proper way to do it. I imagine it has to fit tight, I hope no tighter than tapping it in with a piece of wood.
Any info is appreciated,
Thanks
Brian

Re: Installing the Clutch Pilot Bushing
I just wonder if when that bushing was installed it was a bit loose so they knurled it? You may have to ream it so the trans shaft has clearance.

Re: Installing the Clutch Pilot Bushing
And don't forget that you may need to ream it AFTER it is installed. Otherwise, it could be too tight, the shaft could be "stuck" in the bushing, and you might have shifting/grinding problems. There are several posts regarding this.

Re: Installing the Clutch Pilot Bushing
So the bushing had some play in it when I put it on the shaft. I was thinking it might be perfect after installing.
I really had to drive it on though. Damn near broke my left hand lol. I used an old handle from a single jack and cut off the end when it got too splintered too much, I just got it all the way on when I tore up the last 4 inches of it.
It's not totally flush, it hangs out maybe 1/16 . I'm kinda proud though as I'm thinking the machine shop put the first one in and it looks boogered up compared to the one I put in.

Re: Installing the Clutch Pilot Bushing
Hi,
I would measure the bushing ID, and the shaft OD.
They have said on here that some of the new pilot bushings are too small an ID after being driven into the crankshaft hole. Then the bushing holds the shaft too tight when the Cub is assembled, and the clutch shaft won't stop turning when you push the clutch pedal down.
If the bushing is too small an ID it needs reaming. It should be measured, and reamed if needed, when first installed, before putting the clutch on the flywheel.
Try to drive it in more, until it is about even with the edge of the hole in the crankshaft.
Below is a page from the Cub service manual, showing the shaft size, and running clearance, at Spline and clutch shaft.
