What is the best way to size the first gear layshaft bush? I purchased a new bush for a spare transmission I'm building and it appears that the ID is undersized by approximately .010". Has anyone successfully used a small brake cylinder hone for this kind of work?

Thanks a bunch.

hone

Hi Jason,
To hone anything that size I use a 1/4 inch rod about 6 inches long with a hacksawed slot on the end. I fold a small piece of emery cloth in half then tuck it in the slot. I chuck the rod in my die grinder and hone away. It works great for all sorts of things.

I used an adjustable reamer for this job. It worked just fine even though I reamed it a bit larger than I intended. In this case extra clearance is probably a good idea.

A Sunnen or any kind of self-centering type hone would probably be fine--though one would want to make sure there was enough clearance between shaft and bush.

A good sliding fit is too tight under operating conditions, I think.
