Is it a blind bush you are replacing?

If it is, you may find a reamer will leave a small taper near the end. 
 

I usually skim mine very carefully in my lathe using a boring tool. 
 

But that advice is only useful if you happen to have access to a lathe I guess! ??

The lay shaft bush looks like a blind hole but has a core plug on the end I have fitted some with no problems If it does need reamered  out the plug can be knocked out and replaced You might not see it easily it sits behind the sprocket and chain

my problem is I have no access plate I can see yes knock plug out I could cut the old bush and fold old bush put new one in and try shaft see fits if not ream with adjustable reamer use prybar get plug back in I have a new access plate can that be done with my gearbox in bits with a mill or a home made way using sleeve gear as centre mount with cutter
