See Camshaft on page -92 for specifications. 3. Measure the height of each lobe (1, Figure 181) See Camshaft on page -92 for specifications. 4. Measure the diameter of the gear end (1, Figure 182), intermediate (2, Figure 182) and flywheel end (3, Figure 182) bearing journals. See Camshaft on page -92 for specifications. Inspection of Camshaft Bushing and Bores 1. Measure the I.D. of the front bushing and the remaining bores in the cylinder block. See Camshaft on page -92 for specifications. 2. If the camshaft bushing is not within specification, replace it using the appropriate service tool. If the remaining bores are not within specification, the cylinder block will require replacement as there are no bearing inserts used.
