- CAUTION:
Hold the camshaft sprocket firmly and squarely during camshaft sprocket bolt removal/installation. Failure to do so may result in damage to the inside of the camshaft sprocket.
Hold the intake camshaft sprocket (1) with hand from underneath the EN-52461 Cam Phaser Torque Reaction Tool (2) and pull out the EN-52461-1 Holder (2) and the intake camshaft sprocket will drop down in hand so you can remove it. (1)
Hold the exhaust camshaft sprocket (1) with hand from underneath the EN-52461 Cam Phaser Torque Reaction Tool (2) and pull out the EN-52461-1 Holder (2) and the exhaust camshaft sprocket will drop down in hand so you can remove it.
Timing Chain Tensioner Bolt (1) - Remove [2x]
- Timing Chain Tensioner (2) - Remove
Timing Chain (1) - Remove
- Inspect the timing chain guides and replace if worn down to the base material.
Remove the timing chain tensioner plunger (1) from the timing chain tensioner body (2).
- NOTE:
The ratchet mechanism will lock into place when inward pressure is released after it is turned clockwise until it is fully retracted.
Use the J-45027-1 Tensioner Tool Handle (1) to press the ratchet mechanism of the timing chain tensioner plunger (2) inward while rotating it clockwise.
- Release pressure on the ratchet mechanism of the timing chain plunger assembly (2) until it locks into place.
- Remove the J-45027-1 Tensioner Tool Handle (1).
Install the timing chain plunger assembly (1) into the timing chain tensioner body (2).
- NOTE:
Applying pressure to the timing chain tensioner plunger assembly will unlock the tensioner, it will then fully extend if pressure is released prior to installing the EN-955-10A Locking Pin and will need to be reset again.
Push in and hold the timing chain tensioner plunger assembly, insert the EN-955-10A Locking Pin (1) into the timing chain tensioner (2), then release the timing chain tensioner plunger assembly.
Leave the oil filter in place, or oil will continue to drip.
The timing chain tensioner plunger is spring loaded, hold the plunger in place as tensioner is removed to prevent losing components of the timing chain tensioner.
If the ratchet mechanism does not lock into place and begins to extend outward, reapply inward pressure with clockwise rotation until the ratchet mechanism will not rotate further, then release into the locked position.
