Plastigauge, Crank, and Bearings (old, and new?) ALL

posted by  someone claiming to be Gregg Shadduck on  Sun Dec 2 11:27 CST 2001 [RELATED]

I would appreciate help with something that must be obvious, but I don't get it.

I have no micrometer. So as a first cut at understanding the B23FT carcass before me I read the instructions on the Plastigauge sleeve, waited until snow was melting today, and slipped Plastigauge between the connecting rod caps and the crank, and between the main bearing caps and the crank, torqued all to spec, and inspected the squishes.

All were about .003" A little less.

First: OK, I could have guessed that this old engine wasn't going to be _too tight_. And we see it's not.

Second: OTOH, I am relieved that it's not _real_ loose. Beautiful surfaces on the crank! :-)

But: To _mean_ more am I supposed to buy a set of _new_ bearings (shells) and try all this again? Since the readings are really at the upper end of allowances? (And if the new stuff is too loose you try to exchange the bearings?)

I don't mean to make too fine a point of it, but what do old bearings and Plastigauge tell you?

Or find someone with a micrometer?

Thanks! Gregg
