Good advice Bill. Believe it or not some engines will wear the main bearings
faster than the rods. The TR6 is famous for it. The TR3 doesn`t seem to
although it only has three of them. One might also make very certain that
all of the shells in the box are the same. Sometimes they aren`t.
Plastigage is an excellent $.89 tool. If you could get hold of a mic and
check journal roundness, that would be a good idea too. Just be sure that the
crank is tight against the top bearing so that you aren`t pulling the piston
down while tightening the platsigage in place. I had a student do that and
proclaim the clearances were .002 although I could shake the rods.
