Crankshaft, Main Bearings and Flywheel/Crankshaft CRANKSHAFT REGRINDING If journals are worn, tapered, out-of-round, scored or damaged, the crankshaft journals should be reground and correct undersize bearing inserts installed. Regrind cast iron crankshafts only once as well to 0.25 mm (0.10 in.) under standard size. These crankshafts must be lapped afterwards according to the micro-finishing specifications given in this group. Undersize bearing inserts available: 0.25, 0.50, 0.76 mm (0.01, 0.02, 0.03 in.). IMPORTANT: Crankshaft grinding should be carried out ONLY by experienced personnel on equipment capable of maintaining crankshaft size and finish specifications. NOTE:
To avoid damaging steel crankshafts with rolled grooves, only regrind them once to 0.25 mm (0.01 in.) under standard size specified. CD,3274,G15,21 -19-01MAR92 15 22 CTM3274 (01JUL99) 15-22 Saran Liter Engines 060799 PN=119
