Camshaft Bearing: Service and Repair
Replacement
1. Measure the diameter of each bore. (The limit for the bushing in the No.1 bore is the same as for the other bores without bushings). The limit of the
inside diameter is 54.133 mm (2.1312 inch). If the camshaft bore for the first cam bushing is worn beyond the limit, install a new service bushing.
Inspect the rest of the camshaft bores for damage or excessive wear.
2. If the bores without a bushing are worn beyond the limit, the engine must be removed for machining and installation of service bushings. If badly
worn, replace the cylinder block.
3. Remove the bushing from the No.1 bore, using a universal cam bushing tool.
4. Mark the cylinder block so you can align the oil hole in the cylinder block with the oil hole in the bushing. Apply a coating of Loctite (TM) 609, or
equivalent to the backside of the new bushing. Avoid getting Loctite in the oil hole.
5. Use a universal cam bushing installation tool and install the bushing so that it is even with the front face of the cylinder block. The oil hole must be
aligned. A 3.2 mm (0.128 inch) diameter rod must be able to pass through the hole.
6. Measure the installed bushing. The limit of the inside diameter is 54.133 mm (2.1312 inch).
