IMPORTANT: The engine block camshaft bearing bores are machined for 3 different outside diameter (OD) size bearings. Positions 1 and 5 are
the largest diameter bores. Position 3 is the smallest diameter bore. Positions 2 and 4 are the intermediate size bores. The inside diameter (ID) for
all camshaft bearings is the same size.
1. Measure the engine block camshaft bearing bores (1-5) to identify the correct OD size bearing for each position.
2. Select the expanding driver (4-8) and washer (2 or 3) from the J 33049.
3. Assemble the tool.
4. Insert the tool through the front of the engine block and into the bearing.
5. Tighten the expander assembly nut until snug.
6. Push the guide cone into the front camshaft bearing to align the tool.
7. Drive the bearing into the block bore.
8. Repeat the above procedures to install the remaining bearings.
