    Crankshaft Conversion Help Needed........... Empty Crankshaft Conversion Help Needed...........

    Post by TallGuy Tue Mar 13, 2012 8:02 am

    I have purchased a rebuilt 1978 200ci motor which was previously mated to an automatic transmission. I currently have a tired 170ci motor in my 1963 E100 pickup mated to a 3 speed manual transmission.
    I want to keep the manual transmission but I am being told that I need to get a pilot bearing/bushing (not shure which as I have heard it called both)into the end of the crankshaft on the new motor.
    I would like to be able to do this without having to pull a freshly rebuilt motor apart (I know, I should have done my home work before I bought it) and get it done as inexpensively as possible.
    The two methods I have heard about are as follows:
    1. Use a pilot bushing/bearing adaptor, apparently the bushing/bearing has a knurled outer edge that can be pressed into the opening on the crankshft. I have been unable to find such an adapter so any help there would be appreciated.
    2. Tapping the opening in the crankshaft and screwing in a bushing/bearing. I don't have the ability to tap the crankshaft so I would probably have to take it to a machine shop which sounds kind of expensive.
    So, these are the two methods I have heard of, any guidance you can provide owuld be greatly appreciated!
    Thanks

    The bushing is just pressed in. You can do it with the engine out. Most people just drive them in with a hammer and a deep socket. The hard part is getting an old worn bushing out but you don't have that problem because the AT does not use one. I am not sure if a roller bearing pilot is available for the small six. I prefer the bronze bushing anyway.
