30.
Position actuator in vertical position in vise (rod tip down) and clamp actuator body in vise lightly, (Figure 3).
NOTES:
^
Allow oil to drain to boot end for at least 5 minutes prior to refilling.
^
The actuator assembly uses a tapered bushing between the actuator and mounting base. Do not lose or damage the bushing when removing the
actuator assembly.
31.
Straighten out a standard paper clip (0.032 inch diameter, no serrations) to a minimum straight length of 47 mm (1.85 inches). Form a double loop
in the remaining end of the paper clip, (figure 4).
32.
Rubber end plug from the rear of the actuator assembly. The assembly is filled with oil and removal of the plug may allow oil to escape. DO NOT
REMOVE VENT LUG.
33.
Push the paper clip through the center of the vent plug and into the pilot hole.
34.
Insert a small screwdriver into the screw slot inside the actuator, behind the rubber end plug.
35.
Retract actuator plunger by rotating screw in a clockwise direction, until it is fully retracted. Push on paper clip and slowly rotate screw
counterclockwise until paper clip engages.
36.
Timing belt.
NOTE: Remove timing marks from camshaft and intermediate shaft sprockets.
37.
Rotate crankshaft so the # 1 cylinder is at TDC (top dead center). Mark the timing indicator with white paint (or equivalent) on the crankshaft
balancer and front cover.
38.
Position camshafts so the flat spots are "up" for installation of J-38613-A.
39.
Install J-38613-A on both camshaft carriers.
40.
Camshaft sprockets, (figure 2). Remove bolts, taper lock rings, and sprockets by lightly tapping on it with a soft faced hammer.
INSTALL OR CONNECT
1.
Camshaft sprockets with taper lock rings finger tight.
2.
Timing belt in a counterclockwise direction around the sprockets. Make sure timing belt teeth are fully engaged with all sprockets.
3.
Timing belt tensioner pulley and tighten tensioner pulley bolt to 50 Nm (37 lb ft).
4.
If actuator oil has been lost, till the actuator with SAE 5W30 Mobile 1 (or equivalent) synthetic engine oil through the end hole. Fill to bottom of
plug hole ONLY when actuator is fully retracted and pin is installed.
5.
Rubber end plug to rear of the actuator assembly. Push until flush and snapped into place. Make sure the end plug has sealed against the case.
6.
Actuator bushing into side plate.
Inspect: Bushings and appropriate holes to make sure they are clean. DO NOT lubricate.
7.
Timing belt actuator and actuator side plate and tighten side plate bolt to 27 Nm (20 lb ft).
