Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Thoroughly clean the gasket material from the cylinder block and both sides of plate (19).
Illustration 1 g00576241
Typical example
Install a new gasket (25) on the cylinder block.
Illustration 2 g00596260
Typical example
Install plate (23) and bolts (24).
Tighten bolts (24) to 55 10 N m (41 7 lb ft).
Tighten bolts (24) to 55 10 N m (41 7 lb ft) again.
Install shaft assembly (20). Apply Tooling (B) to the studs and the bolt for the shaft assembly. Tighten the nuts and the bolt for the shaft assembly to a torque of 55 10 N m (41 7 lb ft).
Hand tighten the nuts and the bolt for shaft assembly (20) to a torque of 55 10 N m (41 7 lb ft) again. Note: The backlash for the camshaft gear and the adjustable idler gear will need to be readjusted if shaft assembly (19) has been removed, loosened, or moved in any way. The camshaft gear must be installed and the adjustable idler gear must be removed in order to perform the backlash adjustment procedure. Refer to Testing and Adjusting, "Fuel System".
Install shaft assembly (19). Do not tighten the nuts and the bolt for shaft assembly (19) at this time. The nuts and the bolt for shaft assembly (19) will need to be tightened when the backlash is adjusted.

Bolt tightening sequence for shaft (21)
Apply Tooling (B) to bolts (22). Install shaft (21). Tighten bolts (22) to a torque of 55 10 N m (41 7 lb ft) in a sequence (1, 3, 4, 5, 2, 1, 2, 3, 4, 5, 1).

Typical example
Illustration 5 g00516404
Typical example
Put cluster gear (15) on shaft (21). Ensure that timing Marks (V) are aligned on cluster gear and the crankshaft gear. Apply Tooling (B) to bolts (17). Install plate (17) and bolts (16). Tighten bolts (16) to a torque of 30 7 N m (22 5 lb ft).
Illustration 6 g00596214
Typical example
Put idler gear (11) on shaft (20). Apply Tooling (B) to bolts (12). Install plate (13) with the oil groove toward the gear face. Install bolts (12) and tighten to a torque of 30 7 N m (22 5 lb ft).
Illustration 7 g00596172
Typical example
Note: Skip Step 12 if shaft assembly (19) has been removed, loosened, or moved in any way. The backlash for the camshaft gear and the adjustable idler gear will need to be readjusted. The camshaft gear must be installed and the adjustable idler gear must be removed in order to perform the backlash adjustment procedure. Refer to Testing and Adjusting, "Fuel System".
Put adjustable idler gear (7) on shaft assembly (19). Apply Tooling (B) to bolts (8). Install plate (9) and bolts (8). Tighten bolts (8) to a torque of 30 7 N m (22 5 lb ft).

Illustration 9 g00576839
Typical example
Install O-ring seals (5) and (6) in seal assembly (3). Lightly lubricate the O-ring seal (5) with a 50/50 mixture of Tooling (C) and clean engine oil.
Assemble thrust plate (1) and seal assembly (3). Apply Tooling (B) to bolts (2). Hold the assembly in position and install bolts (2). Evenly tighten bolts (2) until seal assembly (3) and O-ring seal (5) are seated against the cylinder head. Note: Be careful in order to ensure that O-ring seal (5) stays in the groove in seal assembly (3).
Install adapter (4). Ensure that the dowel in adapter (4) engages the hole in the camshaft.
