Remove bolt (1) and the washer from the camshaft gear (2).
Illustration 3 g00541131
Install Tooling (A) and remove camshaft gear. Note: Do not lose the key from the camshaft gear.
Inspect the camshaft gear for wear and damage. Replace the gear, if necessary. Installation Procedure
Illustration 4 g00541130
Install camshaft gear (2) in the front housing. Note: When you install the camshaft gear, ensure that the teeth that have the timing marks are facing toward the front. Also, ensure that the key is aligned properly in the keyway. If necessary, tap the gear with a soft hammer in order to seat the key in the keyway.
If necessary, remove the idler gear in order to align the gear teeth correctly.
Install the washer and bolt (1) on the camshaft gear. Tighten bolt (1) to a torque of 95 N m (70 lb ft). Note: Ensure that the timing marks on the camshaft gear, the crankshaft gear, and the fuel injection pump gear are aligned.
If a new camshaft gear is used, check the backlash of the camshaft gear. The minimum backlash for a new gear is 0.08 mm (0.003 inch). End By:
Install the front cover. Refer to Disassembly and Assembly, "Front Cover - Install".
Install the fan. Refer to Disassembly and Assembly, "Fan - Remove and Install".
