- Fuel Pump - Remove - Fuel Pump Replacement
Adjust the engine to cylinder 1 top dead center (TDC) of the exhaust stroke. Using the crankshaft balancer bolt (3), rotate the crankshaft in direction of engine rotation until the markings (1, 2) line up.
Install the EN-51367 Camshaft Locking Tool (1).
- Timing Chain Upper Guide - Remove - Timing Chain Upper Guide Replacement
- NOTE:
The actuator marks (2) should be at the 12 O'clock position when cylinder 1 is at top dead center.
Mark the camshaft timing chain (1) at the corresponding actuator marks (2).
EN-51367 Camshaft Locking Tool (1) - Remove
- Using a suitable wrench, rotate the intake camshaft clockwise, then release. Repeat this three times to relieve oil pressure from the camshaft timing chain tensioner.
Install the EN-51367 Camshaft Locking Tool (1).
- NOTE:
Do NOT remove or back out the camshaft position actuator bolt(s). Break them loose from their fully-torqued position. The position actuators must stay firmly attached until the retaining tools are in place, they should be broken loose while the chain is still tight and in position.
Camshaft Position Actuator Bolt(1)@Camshaft Position Actuator - Loosen [2x]
Install the EN-51397-2 Timing Chain Retainer (2) to the intake side of the camshaft timing chain (3).
- Install the EN-51397-1 Timing Chain Retainer (5) to the exhaust side of the camshaft timing chain (3).
- Hand tighten the thumb wheels (1, 4) securely.
Install the EN-51397-1 Timing Chain Retainer (1)to the exhaust side of the camshaft timing chain.
- Tighten bolt (2)of the EN-51397-1 Timing Chain Retainer (1) to 5N.m (44 lb in).
Install the EN-51397-2 Timing Chain Retainer (1)to the intake side of the camshaft timing chain.
- Tighten the bolt (2)of the EN-51397-2 Timing Chain Retainer (1)to 5N.m (44 lb in).
Remove and DISCARD the intake camshaft position actuator bolt (1).
- CAUTION:
Do not pry against the face of the camshaft position actuators or the position actuator retaining bolts as the position actuators will be damaged.
Position a screwdriver or small pry bar between a camshaft cap and camshaft lobe. Carefully pry the camshaft to move as far as possible toward the rear/flywheel end of the engine to help gain clearance for actuator removal.
- Pull the camshaft actuator straight back and off the nose of the camshaft, leaving it in place temporarily with the timing chain.
Disengage and lower the intake camshaft position actuator (1) from the timing chain (2).
Camshaft Position Actuator(1) - Remove
Remove and DISCARD the exhaust camshaft position actuator bolt (1).
- CAUTION:
Do not pry against the face of the camshaft position actuators or the position actuator retaining bolts as the position actuators will be damaged.
Position a screwdriver or small pry bar between a camshaft cap and camshaft lobe. Carefully pry the camshafts to move as far as possible toward the rear/flywheel end of the engine to help gain clearance for actuator removal.
- Pull the camshaft actuator straight back and off the nose of the camshaft, leaving it in place temporarily with the timing chain.
Disengage and lower the exhaust camshaft position actuator (1) from the timing chain (2).
Camshaft Position Actuator(1) - Remove
Perform step 3 if the Intake camshaft position actuator is being removed.
Refer to Fastener Caution .
The camshaft timing chain will be held by the EN-51397 Timing Chain Retainers.
