Revotron 1.2T 64 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).
