A 2P-5518 Bearing Tool 1 Start By:
Remove the engine oil pan.
Illustration 1 g01011713
Remove crankshaft main bearing cap (1). Note: Remove No. 1 and No. 7 crankshaft main bearing caps (1) after No. 2 through No. 6 crankshaft main bearing caps have been installed.
Remove the lower half of crankshaft main bearing (2) from crankshaft main bearing cap (1).
Illustration 2 g01147837
If the crankshaft is turned in the wrong direction, the tab of the crankshaft main bearing will be pushed between the crankshaft and the cylinder block. this can cause damage to either or both the crankshaft and the cylinder block.
Install Tooling (A) into the crankshaft journal.
Turn the crankshaft in order to remove the upper half of crankshaft main bearing (2). In order to get out the tab first, the crankshaft must be turned in the correct direction.
Check the condition of the crankshaft main bearings. Refer to the Guideline For Reusable Parts, SEBF8009, "Main and Connecting Rod Bearings" or refer to the Guideline For Reusable Parts, SEBV0544, "Engine Bearings and Crankshafts".
Remove thrust plate (3). Installation Procedure

B 8T-5096 Dial Indicator Group 1 Note: Apply clean engine oil to the crankshaft main bearings prior to assembly. Do not apply oil to the back of the crankshaft main bearing. Ensure that the tabs on the back side of the crankshaft main bearings fit in the grooves of the crankshaft main bearing caps and the cylinder block.
Ensure that the crankshaft main bearings are installed in the correct locations. Two different part numbers are used in quantities of three and four. The part number having the quantity of four is to be installed on crankshaft main bearings 2, 3, 5, and 6. The part number having the quantity of three is to be installed on crankshaft bearing 1, 4, and 7. The thrust plate is to be installed on the center crankshaft main bearing only.
Illustration 3 g01147837Note: The crankshaft end play is controlled by thrust plate (3). Thrust plate (3) is located at the center of the crankshaft.
Install thrust plate (3).
Use Tooling (A) to install the new upper halves of crankshaft main bearings (2) in the cylinder block. This half of the bearing has an oil hole.
Illustration 4 g01011713
Install the new lower halves of crankshaft main bearings (2) in crankshaft main bearing caps (1). Do not apply oil to the back of the crankshaft main bearing. Note: Crankshaft main bearing caps (1) should be installed with the part number toward the right side of the engine. The numerical sequence is identified by stamped numbers 1 through 7 that are located on the bottom surface. The thrust plate is used on the number 4 crankshaft main bearing only.
Position crankshaft main bearing caps (1) with the part numbers toward the right hand side of the cylinder block. Position crankshaft main bearing caps (1) in a numerical sequence. Note: Use new bolts for the installation of bearing caps
