J 33049 Camshaft Bearing Service Set

Important: The engine block camshaft bearing bores are machined for 3 different outside diameter (OD) size bearings. Position 1 and 5 are the largest diameter bores. Position 3 is the smallest diameter bore. Position 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) in order to identify the correct OD size bearing for each position. Refer to Engine Mechanical Specifications.



2. Select the expanding driver (4-8) and washer (2 or 3) from the J 33049 . Refer to Piston and Connecting Rod Assemble.
3. Assemble the tool.
