Do not damage the lobes or the bearings when the camshaft is removed or installed.
Note: During the installation of the camshaft, rotate the camshaft in both directions in order to prevent binding in the camshaft bearing bores.
Lubricate the camshaft lobes and the valve lifter bore with a 50/50 mixture of Tooling (B). Apply clean engine oil on the camshaft bearing journals. Carefully install camshaft (10) in the cylinder block.

(5) Gear for the high-pressure fuel pump
(6) Camshaft gear
(7) Idler gear
(8) Crankshaft gear
(9) Timing marks
When installing the camshaft, make sure the number one cylinder is at top center of the compression stroke with the timing bolt installed in the flywheel. The camshaft timing is very important. The timing mark on the camshaft drive gear must line up with the timing mark on the idler gear. Refer to the Specifications Manual for more information.
Correct fuel injection timing and correct valve mechanism operation is determined by properly timing crankshaft gear (8) and camshaft gear (6) to idler gear (7). Also, high-pressure fuel pump gear (5) must be timed to camshaft gear (6). During installation of the front gear, timing marks (9) on idler gear (7) must be in alignment with the timing marks on crankshaft gear (8) and the timing marks on camshaft gear (6). The "0" mark on camshaft gear (6) must align with the timing mark on idler gear (7). The "V" mark on camshaft gear (6) must align with the "V" mark on fuel pump gear (5).

Install thrust plate (4) and bolts (3).
The maximum permissible end play for a worn camshaft is 0.46 mm (0.018 inch). The maximum permissible end play for a new camshaft is 0.13 0.08 mm (0.005 0.003 inch).
Use Tooling (A) to position the valve lifters in the cylinder block.
Calibrate the speed/timing sensor. Refer to Troubleshooting, "Engine Speed/Timing Sensor - Calibrate". End By:
Install the front cover. Refer to Disassembly and Assembly, "Front Cover - Install".
Install the rocker arm and the shaft. Refer to Disassembly and Assembly, "Rocker Arm and Shaft - Install".
