Secondary Timing Chain RH

Removal

NOTE: Vehicles without supercharger shown, vehicles with supercharger similar.

1. Remove the right-hand primary chain. For additional information, refer to Primary Timing Chain RH Right-Hand





2. Push the tensioner piston (secondary chain) into the body to to release the tension on the right-hand secondary timing chain.
Insert a thin rigid wire through the hole in the end of the tensioner piston to displace the ball from the non-return valve seat.
With the wire in position, press the piston fully into the tensioner body.
Remove the wire.





3. Remove the secondary timing chain.
Remove the variable camshaft timing oil control unit (or intake camshaft sprocket - vehicles fitted with supercharger) and exhaust camshaft sprocket retaining bolts.
Remove the variable camshaft timing oil control unit (or intake camshaft sprocket - vehicles fitted with supercharger), exhaust sprocket and secondary chain as an assembly (release the chain from the tensioner which is still secured to the cylinder head).
Remove the secondary chain from the variable camshaft timing oil control unit (or intake camshaft sprocket - vehicles fitted with supercharger) and the sprocket.

4. Clean and inspect all relevant components.

Installation





1. Install the secondary timing chain.
Fit the assembly to the camshafts with the chain correctly positioned over the tensioner; variable camshaft timing oil control unit (or intake camshaft sprocket - vehicles fitted with supercharger) to the inlet and the sprocket to the exhaust.
Fit, but do not tighten, each bolt which secures the variable camshaft timing oil control unit (or intake camshaft sprocket - vehicles fitted with supercharger) and the exhaust sprocket to the camshafts. Allow the variable camshaft timing oil control unit sufficient space to fit the primary chain, in a later operation.

2. Install the right-hand primary chain. For additional information, refer to Primary Timing Chain RH (12.65.66) (Section )
