Turn the camshaft gear by hand in the opposite direction

as far as it will freely move, and read the dial indicator.

Backlash Between the Camshaft and the

Crankshaft Gears

mm in

0.05 MIN 0.002

0.50 MAX 0.020

If the backlash is excessive, inspect the camshaft and

crankshaft gears for tooth wear and replace if necessary.

If the backlash is tight, inspect for debris or damage to the

gear teeth and check again.

Cam Follower Assemblies - Installation

Install the new cam follower gaskets to the block as fol-

lows:

• Obtain a gasket with the same thickness as the

gaskets removed.

• Install the gaskets over the dowel pins in the block.

NOTE: If the thickness of the original gaskets is unknown,

install a gasket combination of 0.99 mm [0.039-inch] as a

reference point.

NOTE: The Print-O-Seal gasket must be against the cylin-

der block with the sealing bead toward the cam follower

housing.

Use clean 15W-40 oil to lubricate the camshaft lobes.

Install a new gasket on the guide studs and the dowels

for the No. 1 cam follower housing.

Install the cam follower assembly as follows:

• Install the capscrews and the studs in the same

position from where they were removed. Tighten the

capscrews in the alternating sequence shown to the

following torque values:

— Tighten to 20 N•m [15 ft-lb].

— Tighten to 47 N•m [35 ft-lb].

Injection Timing - General Information

The injection timing is the relative measurement of the

distance remaining between the injector plunger and the

injector cup when the piston is 5.161 mm [0.2032-inch],

or 19 degrees before top dead center (TDC) on the com-

pression stroke.

Injector timing is expressed by the amount of push tube

travel remaining.
