Good day all, this is my first post here so I hope I am doing things correctly.
About 25 years ago I purchased a CS 12-2 in a farm auction as the crank was missing I never tried to start her. Stashed her in the barn for a rainy day. Last week I decided I needed a winter project so I moved her into the shop. I rebult a couple of Petter engines about 40 years ago when in the UK they were on "Dumpers". So not completly green.
So far I have found an oil pipe from the oil maifold laying in the sump, the union nut was broken and the solder repair hadn't lasted. Although she turns over very easily the big end bearings need replacing. Removed the heads and blocks. Valves aren't to bad. A small piece of linner skirt was broken off and also in the sump. A con rod must have conected with it at some time. Bores are excellent and rings appear good. With the big end bearings gone I decided to check the main bearing, she is not good. Oh well "in fior a penny in for a pound". Time to remove the crank.
I had been soaking the gib keys in penetrating oil for a week, had a local machine shop mke me a HD key puller but no luck. I can crack the key heads before they will move, they are welded and waiting for tomorrow.
My question to anyone who has worked on these engines, how hot can you heat the flywheel hub? I have a large "Rose Bud" tip on my torch and had to heat the flat belt drive pully hub cherry red before I could loosen the set screw and remove her. I think this would be a littel excessive for a flywheel!
Any suggestions would be welcolm
