G. Camshaft :
1. Visually inspect the camshaft journals for
signs of overheating and score marks.
2. Visually inspect the camshaft lobes for signs
of excessive wear or score marks.
3. Place camshaft journal 1 and 5 in 'vee blocks'
and check camshaft journal runout on journals
2, 3, and 4 using a dial indicator. The
maximum journal runout is 0.025 mm
4. Measure the diameter of each of the camshaft
journals. Refer the table for acceptable
journals diameters.
5. Use a bore gauge to measure each of the I.D.
of camshaft bearings. Refer the table for
acceptable bearing diameters.
6. Use a magnetic crack detector to check the
camshaft for cracks.
7. Check the camshaft lobes and journals for
proper hardness. The Rockwell Hardness
should be a minimum of 56 on the 'C' scale
(56 HRC).
