REPAIR INSTRUCTIONS Inspection 1. Using a telescope gauge or inside micrometer, measure the auxiliary bushing bores. Take two readings, perpendicular to each other, in each bore. Record the readings. Refer to Figure 168. 2. Compare readings with the tolerances listed in “FITS AND LIMITS” on page 289. 168
2. Using a dark-colored felt-tip marker, mark the block and the bushing with a line (1) to facilitate correct alignment during installation. 3. Clean the surfaces of the bushing and the bore. Dry both surfaces with compressed air. 4. Using camshaft bushing remover/installer kit J 21428-01 (4) and the appropriate pilot adapter J 37713 (3), install the bushing. 169

Installation
Correct installation of auxiliary driveshaft bushings is very important. If bushings are misaligned, lubrication oil will not be allowed to lubricate the auxiliary driveshaft journal. This will also cause the component lubricated through that journal to run without lubrication and prematurely fail. If the oil feed hole in the oil metering plug at the rear of the auxiliary shaft 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 oil hole is not plugged. If replacing the auxiliary driveshaft, make sure to install a new plug.

5. Check the bushing surface for burrs caused by installation.
Refer to Figure 169. 1. Position a replacement bushing (2) against the side of the block at the rear bushing bore. Align the oil hole in the bushing with the hole in the block.
Refer to “FITS AND LIMITS” on page 289 for correct bushing ID dimensions.
