Remove And Install Crankshaft Main Bearings
start by: a) remove oil pumpb) remove oil pan plate 1. Remove the odd number main bearing caps (1) of the crankshaft.2. Remove the upper halves of main bearings as crankshaft is turned and bearing is moved out of the cylinder block with tool (A). Remove lower halves (2) of main bearings from caps.3. Put clean SAE 30 engine oil on upper halves of main bearings. Put upper halves of main bearings into place with tool (A).4. Clean the main bearing caps, and install lower halves of bearings in caps. Make sure the crankshaft is held up against the upper main bearings with a force equal to the weight of the crankshaft. 5. Check the bearing clearance with wire (B). Install caps and turn bolts to a torque of 30 3 lb.ft. (40 4 N m). Put a mark on both bolt heads and bearing caps, then turn each bolt 90° more. Remove the bearing caps, and measure thickness of wire. Main bearing clearance with new bearings must be .0030 to .0065 in. (0.076 to 0.165 mm). Maximum permissible clearance with used bearings is .010 in. (0.025 mm).6. Put clean SAE 30 engine oil on threads of cap bolts, face of washers and lower halves of main bearings. Put the caps (1) in position on engine with number on cap in direction of respective number on pan face on left side of cylinder block. Install bolts and washers. Turn both bolts to a torque of 30 3 lb.ft. (40 4 N m). Put a mark on both bolt heads and bearing caps, then turn both bolts 90° more.7. Remove the even number main bearing caps. Remove the crankshaft thrust bearings. Put clean SAE 30 engine oil on the new thrust bearings and install them in cylinder block with groove in bearing against crankshaft.8. Do Step 2 through Step 6 for the remainder of the bearings. Check crankshaft end play with indicator group (C). End play with new bearings must be .0025 to .0145 in. (0.064 to 0.368 mm). Maximum permissible end play with used bearings is .025 in. (0.64 mm).end by: a) install oil pan plateb) install oil pump
