Re: Engine Rebuild

Well I can tell you your chances of success are much better if you start with an engine that doesn't have a bad bearing. An eg33 with a bad bearing is an eg33 with a bent crank. A bent crank means both the mains and pins will have to be ground. When they grind a crank they grind all the mains to one size. Unfortunately the holes for the main bearings in the block are not all the same size. Getting the crank right requires caging your new bearing set in the block(caging = assembling the block, torqued correctly, around the bearings after it is cleaned up but without the crank) and measuring each bearing bore then belt polishing each crank journal to match the corresponding bearing.

While we are on the subject EG33 cranks can not be left standing around the shop like most shops do with most cranks. This is not a big heavy cast crank. It will get bent if not pampered. It should be kept sitting in the bearings of one of the block halves.
