REPAIR INSTRUCTIONS
Make sure oil is applied 360 degrees around the lobes and journals. Lubri-plate type break-in grease may be substituted for engine oil. 5. Carefully insert the camshaft into the block using installation guide tool J 41461. Align the timing marks on the camshaft with the timing mark on the crankshaft main drive gear. Refer to Figure 291.
The use of the installation tool makes it easy to slide the camshaft into the block while protecting the camshaft and bushings from damage.
6. Secure the camshaft captured thrust washer to the block using the two patch-lock 12-point capscrews and hardened washers. Torque to 15 lb-ft (20 N•m) using torque wrench J 24406, or equivalent.
Auxiliary Driveshaft Installation INSPECTION 1. Using standard shop procedures, thoroughly clean auxiliary driveshaft. 2. Inspect auxiliary driveshaft journals, gear teeth and splines for evidence of cracks, pitting, scoring or severe wear. Replace auxiliary driveshaft if any of these conditions exist. 3. Use magnaflux (PT7190, or equivalent) inspection procedures to detect cracks.
291
Note the oil feed hole in the oil metering plug at the rear of the auxiliary shaft. If this hole is plugged up, the raw water pump may fail from oil starvation. Also, the loss of oil pressure that results from a missing plug can cause damage and problems in other components and parts. Make sure the plug is not missing or the metering hole is not plugged. If replacing the auxiliary driveshaft, make sure to install a new plug. 292
