How were you able to hone the bushing inside the crank, what did you use to widen it a bit? I feel like I pushed the bushing a bit hard putting it in and now I may need to hone the inside a bit. It was a real tight fit going in.

I see people talking about the "clutch pilot tool" what is that? And would it help me on install to not mess up the face of the pilot bushing on install?

This tool is plastic and is made to help with the alignment of the clutch and pressure plate. It would not take much pounding.

Here is a picture for TM's site. Mine is a little different. It doesn't have the ring on the end.

Okay thanks Ken. I actually purchased that from you. I also purchased a pilot bushing but man it was so tight going in I may have mushed it up a bit on install.... I am going to try and hone it a bit of I can but just don't know what people are using to hone there bushing. If that does not work I ordered another one from you yesterday and will have to put that in. I hope it does not fit as snug. May try the cold method next to to shrink it a bit.

I am not associated with TM Tractor Parts but that's where I purchased my new bushing a tool. It should be a snug fit so it won't spin but not that tight.....put a little grease on it first.

I see thanks Ken. So how are you guys installing this bushing with out tearing it up? Or how are you reaming it out once its in the tractor?

I made myself a stepped arbor on a lathe to tap mine in-perhaps a little over the top. You could use the old bushing to tap on/in the new one, a hardwood dowel, or anything that avoids marring/hammering directly on the edge of the new bushing. You should be able to tap directly on it with a soft face dead blow hammer.

I used a make shift "hone" by sawing a slit in the end of a 6-8" rod , about the length of the bushing. A steel or wood rod will work- it just needs to fit in your drill chuck. Insert the end of a strip of sandpaper(120-150 grit) in the slot and wrap it around the rod as much as needed to get close to the bushing ID size. The tighter you can wrap it the better. Chuck the other end in your drill ( you have to hold the paper tight until its in the bushing) and hone as much as necessary. Make sure your drill direction is correct (so the paper gets tighter as it spins.) This depends on which way it was wrapped around.

I would recommend getting the bushing close to size before putting it in (which it should be) and then finish as needed after installing it.
The bushing is fairly soft so make sure you check size often-it doesn't take much. Clean all abrasive material out when done and before lubricating.

hope this helps. tim

Thanks so much Tim for the response I will give it a try. Has anyone cooled the bushing before install or heated the crank area before putting the bearing inside? Would that allow it to go in much better?
