Section 4 - Cam Follower Assembly - Group 04 Magnetic Crack Inspection (04-04) M11 Page 4-17 Measure the cam follower roller side clearance. Roller Side Clearance mm in 0.19 MIN 0.007 0.65 MAX 0.026 If the roller does not rotate freely or the side clearance does not meet the specifications, the cam follower lever must be rebuilt again. Use a dial indicator to measure the cam follower roller to pin clearance. Roller to Pin Clearance mm in 0.08 MIN 0.003 0.20 MAX 0.008 NOTE: If the roller to pin clearance is not within these speci- fications, the roller and pin must be replaced. Refer to Cam Follower Lever - Roller Replacement (4-03).
Cam Follower Lever - Magnetic Crack Inspection (Roller Removed) (4-04) Use coil magnetization with residual magnaglow to magnitize the cam follower levers. Amperage 300 Ampere Turns min. 500 Ampere Turns max. Visually inspect the levers for cracks. Cracks will appear as a solid bright line. Discard cracked levers. Use a demagnetizer to remove the magnetism. Use solvent to clean the cam follower levers. Dry with compressed air.
