7. Remove the lower insert from the bearing cap.
8. Remove the upper insert by LOOSENING (DO NOT REMOVE) all of the other bearing caps. Now insert a small cotter pin tool in the crankshaft
journal oil hole. Bend the cotter pin as illustrated to fabricate the tool (Fig. 69). With the cotter pin tool in place, rotate the crankshaft so that the
upper bearing insert will rotate in the direction of its locking tab. Because there is no hole in the No.3 main journal, use a tongue depressor or
similar soft-faced tool to remove the bearing insert (Fig. 69). After moving the insert approximately 25 mm (1 inch), it can be removed by
applying pressure under the tab.
9. Using the same procedure described above, remove the remaining bearing inserts one at a time for inspection.
INSTALLATION
1. Lubricate the bearing surface of each insert with engine oil.
2. Loosen all the main bearing caps. Install the main bearing upper inserts.
3. Install the lower bearing inserts into the main bearing caps.
