Thrust Bearing
Thrust bearing is part of main bearing No. 3. Using a rubber mallet, tap crankshaft forward then rearward to seat thrust bearing. With main bearing cap bolts tight, check crankshaft end play. If end play exceeds specification, replace main bearing No. 3 and/or crankshaft. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS table under ENGINE SPECIFICATIONS.

A .0050" (.125 mm) oversize piston can be fit on cylinder by honing cylinder, but a .0157" (.400 mm) oversize piston requires cylinder to be bored.
