NOTE: Typical camshaft shown.
To check the intake and exhaust lobes, measure across diagonally (A-C) and across horizontally (B-D). Subtract (B-D) from (A-C). This will give cam lobe lift. Install a new camshaft when cam lobe lift wear exceeds specifications. For additional information, refer to SPECIFICATIONS .
- Inspect the thrust plate for wear, cracks or distortion.
- Inspect the camshaft drive gear for worn or damaged teeth.
- Wash the camshaft in cleaning solvent with a soft brush. Dry with filtered, compressed air.
