Turn the crankshaft to top center compression stroke for the No. 1 piston. The "C" mark on the crankshaft gear will be aligned with the "C" mark on the camshaft gear.
Illustration 2 g00476743
Note: Put a mark on the teeth of the fuel injection pump drive gear and the idler gear at location (A). This will help to keep the engine timing correct during the removal and the installation of the camshaft. Put a mark on the teeth of the idler gear and camshaft gear (2) at location (B). When the camshaft is installed, the engine timing will be correct when the mark at location (A) is aligned with the mark at location (B) and the "C" mark on the crankshaft gear is aligned with the "C" mark on the camshaft gear.
Remove the bolts, the lock and washer (1) .

Put camshaft drive gear (2) in position on the end of camshaft (3). Install the bolts that hold camshaft drive gear (2) to camshaft (3). Tighten the bolts to a torque of 55 7 N m (41 5 lb ft).
Do not damage the lobes or the bearings when the camshaft is installed.
Put 8T-2998 Camshaft Lubricant on the camshaft lobes only and put clean engine oil on the bearing journals. Note: During the installation of camshaft (3), rotate the camshaft in both directions in order to prevent binding in the camshaft bearing bores.
Carefully install camshaft (3) into the engine.

Make sure that the mark on the teeth of the fuel injection pump drive gear and the idler gear are in alignment at location (A). Make sure that the mark on the teeth of the idler gear and camshaft gear (2) are in alignment at location (B). Align the "C" marks on the crankshaft gear and camshaft gear (2). When all of the timing marks are in alignment the engine timing is correct.
Install washer (1), the lock and the two bolts that hold the camshaft in position in the engine.End By:
