need parts to rebuild ST1 engine

[Farmer]

I'm working on an ST1 that needs new bearings oversize piston & rings, etc.  I need some help in finding a parts supplier.  Thanks for any assistance

Gary Jones at Diesel Electric Service in Kansas should have every thing you need for an ST1

Thanks very much.  Looks like he has everything

Have rec'd parts & beginning to put back together.   How do I change the main bearing?  I think I can make a tool to press the the one in the crankcase, but not sure hoe to deal with the other end.  Thanks for any advice.

Hi Farmer, I`m a little confused by your question. The main bearings are shell bearings and can easily be replaced by undoing the bearing caps.
My guess is: you are talking about the brass/bronze bushes on the camshaft, in the service manual Lister specify a purpose made tool for removing/fitting these. I don`t believe that tool is still available to buy. I made a puller out of a suitable sized piece of round bar with a thread down the middle of it, I used a large socket, a washer, piece of thread rod and nut and slowly pulled it out by tightening the nut. I installed the replacement the same way.
Hope this helps.
