Pilot Bushing Problem
Rebuild clutch & transmission for 1927 Capital AA with a 1928 engine. first time. Removed old pilot bushing to install new and it appears there was a metal sleeve around the bronze bushing which is still in the crank blind hole along with a bronze spacer at the rear. The opening in the crank measures .775 the removed pilot bushing outside measures .7775. The new pilot bushing, the one I am trying to install measures outside at .815 and inside at .6215. The work has been done with the engine installed in the auto. Do not know if pilot bushings ever had a metal sleeve or jacket. Would like to know the dimensions the original bored hole in the crank. Do not know if I will be able to remove the spacer in the bottom of the hole and the metal sleeve? I could have the bushing turned down but would have to know how many thousand over the existing hole size is required to prevent movement of the bushing. Being of 43 vintage I am hoping another vintage member will have more insight than myself. I have a picture but do not know if I will be able to download it. Thanks for all that you do…Jim43

Sounds like a real pickle. I am not sure it will work on a sleeve such as the one you have described. My dad showed me this trick of hydraulically removing a pilot bearing many years ago. Pack the whole thing with the thickest grease you can find. Then make a wood plug a few thousands bigger than the hole maybe 6" long. Drive the plug into the hole. If it works and gets the sleeve out that is great. If it does not you can still turn down your Sintered pilot bearing. Once it is in there you probably will not have to worry about it ever again.

Was looking and tinkering with the sleeve that remained in the blind hole and was able to remove it. There was no spacer at the bottom of the blind hole just a smaller diameter that is part of the crank. The bushing I believe is a piece of copper pipe or tubing with a small piece of tin wrapped around it and it overlapped
.which accounted for the copper to be worn more on one side. Who would have imagined
