Inspection of Camshaft

nInspection Steps:

1. Use V-blocks and a dial indicator to measure camshaft bend on the center bearing journal.
2. Rotate the camshaft to observe runout specifications (see page -92).
3. Measure the height of each lobe (see Figure 181, page -92).
4. Check the diameter of the gear end, intermediate, and flywheel end bearing journals (see Figure 182, page -92).

Inspection of Camshaft Bushing and Bores

1. Measure the inner diameter (I.D.) of the front bushing and other cylinder block bores.
2. If the bushing is out of specification, replace it using the appropriate tool. Any cylinder block bores not within specification will require replacing the block itself, as it lacks bearing inserts.
