2. Remove the nuts (1), washers, and bearing caps from the cylinder block.3. Remove the crankshaft from block. Weight of crankshaft is 240 lb. (108 kg).4. Remove the bearings from main bearing caps. 5. Remove the upper halves (2) of bearings from the cylinder block.Install Crankshaft
1. Clean the surfaces for bearings in cylinder block. Install the upper halves of bearings in the block. Put clean oil on the bearings. 2. Fasten a hoist and put the crankshaft in position on block with "V" mark on crankshaft gear in alignment with "V" mark on cluster gear.3. Clean the bearings caps, and install the lower halves of bearings in caps. 4. Use wire (A) to check bearing clearances. Install the bearing caps, and tighten both nuts to 70 5 lb. ft. (9.7 0.7 mkg). Put a mark across the nuts and studs, and turn nuts an additional 90° from mark. Remove caps and check thickness of wire (A) to find bearing clearance. Bearing clearance must be .0030 to .0059 in. (0.07 to 0.14 mm) for new parts. Maximum permissible clearance for used parts is .010 in. (0.254 mm).5. Put clean engine oil on threads of studs, face of washers, and lower halves of bearings. Put the bearing caps in their respective positions with number on cap on same side and the same as number on cylinder block. Install washers and nuts. Tighten nuts to 70 5 lb.ft. (9.7 0.7 mkg). Put a mark across the nuts and studs, and turn nuts an additional 90° from mark as shown. 6. Use indicator group (B) to check the crankshaft end play as controlled by bearing (1) on No. 4 main bearing cap (2). End play with new parts should be .011 to .018 in. (0.28 to 0.46 mm). Maximum permissible end play with used parts is .035 in. (0.89 mm).end by: a) install timing gear housingb) install pistonsc) install front cover
