Default Re: babbit tolerance? .000?

The fact remains,with poured bearings or precision insert bearings the assembler should insure the assembly has proper clearance. My experience with diesel and gas engine assembly,regardless of compression pressure or size of components a properly fit crankshaft to spec spins freely by hand.That is undeniable and anyone who takes part in assembling an engine with the crankshaft 'frozen' by the bearings displays poor workmanship. Any one who provides a service and is involved with a documentation of his services with the results as shown at the minimum failed to protect his interest,at the maximum displayed that he performs shoddy work and doesn't realize it..either way,its an indictment he freely submitted.
