General Information
Some engines are built with a camshaft bushing installed in the first camshaft bore only, on the same end of the
engine that the camshaft is removed and installed (front gear train engines, at the front of the engine and rear gear
trains, at the rear of the engine). Some engines also have a second camshaft bushing at the opposite end of the
engine from which the camshaft is removed and installed.
From production, there are no camshaft bushings installed in the inner block camshaft journal bores. If the inner block camshaft journal bores are damaged, the journal bores can be machined for camshaft bushings.
Use the camshaft bushing replacer kit, Part Number 3165045, to remove the camshaft bushings. The tool will
drive the camshaft bushing to the inside of the block. The camshaft bushing can be retrieved from the bottom of the
engine.
NOTE: Once removed, camshaft bushings can not be reused.
