Camshaft Bearing Journal Diameter

Camshaft Bearing Journal Diameter
1. Determine the diameter of the camshaft journals.

^ Using a micrometer measure the diameter at 90 degrees intervals to determine if the journals are out-of-round.
^ Measure at two different points on the journal to determine if there is any tapering.
^ If the measurements are out of the specified range, install a new camshaft.
