Rear Gear Train
Apply assembly lubricant, Part Number 3163087, to the rear camshaft bore.
Lubricate the camshaft lobes, journals, and thrust washer with assembly lubricant, Part Number 3163087 .
Use a gear puller, Part Number ST647 or equivalent, to attach to the end of the camshaft where the camshaft gear
mounts to act as a handle. This will give proper leverage and ease installing the camshaft.
NOTE: The following illustrations show the engine in the upright position for clarity.
Install the camshaft. While pushing in lightly, rotate the camshaft and carefully work the camshaft through the
camshaft bushings. As each camshaft journal passes through a bushing, the camshaft will drop slightly and the
camshaft lobes will catch on the bushings. Rotating the camshaft will free the lobe from the bushing and allow the
camshaft to be installed.
Install the thrust plate.
Torque Value: 24 N•m[ 212 in-lb ]
Front Gear Train
Apply assembly lubricant, Part Number 3163087, to the front camshaft bore.
Lubricate the camshaft lobes, journals, and thrust plate with assembly lubricant, Part Number 3163087.
NOTE: The following illustrations show the engine in the upright position for clarity.
Install the camshaft. While pushing in lightly, rotate the camshaft and carefully work the camshaft through the
camshaft bushings. As each camshaft journal passes through a bushing, the camshaft will drop slightly and the
camshaft lobes will catch on the bushings. Rotating the camshaft will free the lobe from the bushing and allow the
camshaft to be installed.
Before the camshaft gear engages the crankshaft gear, check the camshaft for ease of rotation. When installed
properly, the camshaft must rotate freely.
Align the timing marks as illustrated and finish installing the camshaft.
Install the thrust plate capscrews.
Torque Value: 24 N•m [ 212 in-lb ]
Use gauge, Part Number 3824564, and magnetic base, Part Number 3377399, to verify the camshaft has proper
backlash and end play.
Rear Gear Train
NOTE: On front gear train engines , the camshaft gear is installed with the camshaft.
Align the camshaft gear with the pin in the camshaft and the mark on the crankshaft gear.
Install the camshaft gear onto the camshaft.
Check to make sure the timing marks on the camshaft gear align with the timing marks on the crankshaft gear.
NOTE: The engine can have a mark on the crankshaft gear or chamfered tooth.
Install camshaft gear capscrews and tighten.
Torque Value: 36 N•m [ 27 ft-lb ]
Use gauge, Part Number 3824564, and magnetic base, Part Number 33n399, to check the camshaft end play.
NOTE: If the camshaft end play is out of specification, check the camshaft thrust plate. Refer to Procedure
001-008 in Section 1.
