NOTICE
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.
2. Correct fuel injection timing and correct valve mechanism operation is determined by properly
timing crankshaft gear (9) and camshaft gear (7) to idler gear (8). Also, high-pressure fuel pump gear
(6) must be timed to camshaft gear (7). When installing the front gears, timing marks (10) on idler
gear (8) must be in alignment with the timing marks on crankshaft gear (9) and the timing marks on
camshaft gear (7). The "0" mark on camshaft gear (7) must align with the timing mark on idler gear
(8). The "V" mark on camshaft gear (7) must align with the "V" mark on fuel pump gear (6).

permissible end play for a new camshaft is 0.13 ± 0.08 mm (0.005 ± 0.003 inch).
5. Use Tooling (A) to position the valve lifters in the cylinder block.
6. Calibrate the speed/timing sensor. Refer to Troubleshooting, "Engine Speed/Timing Sensor -
Calibrate".
