Camshaft Bearing: Service and Repair
CAUTION: 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.
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.)
Limit
Inside Diameter: 54.133mm [2.1312 inch]
NOTE: If the bores without a bushing are worn beyond the limit, the engine must be removed for machining and installation of service bushings or
replacement of the cylinder block
Remove the bushing from the Number 1 bore, using a universal cam bushing tool.
NOTE: Mark the cylinder block so you can align the oil hole in the cylinder block with the oil hole in the bushing.
