What ho all.
I've been dismanting my 1937 3 bearing engine today, all was going fine until the removal of the camshaft. We removed the rear bearing cap and the squared headed top/front bearing bolt and the mid bearing bolt. The shaft moves fore and aft slightly but is very tight indeed, it still turns OK. The mid being pieces seem to drift forward reasonably OK, but the problem appears to be at the front bearing. I've consulted Woodrow and the Ian Bancroft magazine article. Presumable some heat needs applying around the front bearing I assume, so I wonder if any others have had similar problems and what would you recommend please?
The pistons are +60, and I've read somewhere that +80 thou is the maximum? Would I be better looking for another block which hasn't been so far bored out, thus allowing perhaps an additional rebore in due course, what do any of you think?
Thanks in advance, and sorry if some questions seem dumb, but this is the first time of dismantling an old engine.
Don't laugh....I can't get the crank out at present!
regards
Arthur
