Remove And Install Crankshaft Main Bearings (D330C, D333C, 3304 & 3306 Industrial Engines)
start by: a) remove oil pan plateb) remove oil pump1. Remove the No. 1, 3 and 5 main bearing caps from the crankshaft. 2. Remove the upper halves of main bearings by turning the crankshaft and moving the bearing out of cylinder block with tool (A). Remove lower halves 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. 5. Check the bearing clearance using wire (B). Install caps and turn bolts to a torque of 30 3 lb. ft. (4.1 0.4 mkg). 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. (0.25 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 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. (4.1 0.4 mkg). Put a mark on both bolt heads and bearing caps, then turn both bolts 90° more.7. Remove No. 2, 4 and No. 6 main bearing caps. Do Steps 2 through 6 for the bearings.8. Remove No. 7 main bearing cap and thrust bearings. Do Steps 2 through 6 for this bearing. Put clean SAE 30 engine oil on the new thrust bearings and install them in cylinder block with groove in bearing against crankshaft. 9. Check crankshaft end play with tool 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 pumpb) install oil pan plateRemove And Install Crankshaft Main Bearings (D330C, D333C, 3304, 3306 & Marine Engines)
start by: a) remove oil pan plate Put numbers on bearing caps as to their locations if the existing numbers can not be seen. 1. Remove No. 2, No. 4 and No. 6 main bearing caps. Use tool (A) to remove upper halves of main bearings by putting tool (A) in oil hole in crankshaft. Turn the crankshaft in the direction which will push end of bearing with a tab out first.
If crankshaft is turned in the wrong direction, the tab of the bearing will be pushed between the crankshaft and cylinder block. This can cause the damage to either or both.
2. Remove lower halves of bearings from caps.3. Put clean engine oil on upper
