(1) Timing marks
(2) Camshaft gear
(3) Adjustable idler gear
(4) Idler gear
(5) Cluster gear
(6) Timing marks
(7) Crankshaft gear
(8) Oil pump gearThe correct fuel injection timing and valve mechanism operation is determined by the alignment of the front gear group timing. Timing marks (1) and timing marks (6) are aligned in order to provide the correct relationship between the piston movement and the valve movement.Required Parts
Used for properly setting backlash on engines.
Tools are based on idler gear tooth count and gear bushing diameter
Used to allow the correct cam gear backlash to be set for any cylinder head (new or re-machined)
Provides easy access to fasteners on the adjustable stub shaft for setting the correct backlash adjustments.
Set before idler gear is installed into place

Front cover is removed.
With the front cover removed, remove bolts (3), plate (2), and adjustable idler gear (1).
Illustration 4 g02686407

With the flywheel pinned at TDC for cylinder one, align timing marks (5).
Install the cam gear backlash tool onto the stub shaft, as shown. Both sides of the gear segment tool should be engaged with the corresponding gear, as shown. Hand tighten the one bolt and two nuts enough so that slight resistance is felt if the stub shaft is rotated.
Illustration 6 g02688245
Measure the backlash between camshaft gear (2) and gear segment tool (3). When the gear segment tool is held stationary, the backlash between the gears is 0.216 0.114 mm (0.0085 0.0045 inch). Lightly tap the stub shaft with a soft mallet to move the gear segment tool closer or further away to the cam gear as necessary. This movement will increase or decrease the amount of backlash.
Illustration 7 g02688540
Once the proper backlash is obtained, tighten the nuts and the bolt (4) to a torque of 55 10 N m (41 7 lb ft).
