I'm rebuilding a little 155d and just put the crank back in the block with new bearings and seals. I'm worried its a little tight. I had the rod journals turned down and the mains checked. Everything went together ok, but how tight it is too tight. I haven't put rods and pistons in yet. The manual just says that you should be able to turn it by hand. Is there a good way to ease it up some without taking the bearings back to what i just replaced? Any help or thoughts on the problem would be appreciated.
