36. Loosen the remaining bolts by a single turn at a time following the sequence below. Repeat as necessary until the bolts
are completely loose.

37. Install four lifting eyes into the rocker cover mounting holes.
NOTE: Ensure that no debris fall into the return oil ports on the cylinder head or severe engine damage can
occur.
38. Connect a suitable lifting device to the lifting eyes.
39. Remove camshaft housing assembly.
NOTE: Because of the pressure on cylinders 2 & 3 rockers, the housing may get stuck on the rear alignment
dowel. If it gets stuck, it can be broken free by rocking down on the front of the housing; if not, a pry bar may be
needed to help break it loose.
40. Remove and discard the camshaft housing seal.
NOTE: Do not rest the camshaft housing assembly on the camshaft gears or damage can occur.
41. Place the camshaft housing assembly on the bench on its side.

Installation of the Camshaft Housing Assembly

Install as follows:
NOTE: Do not remove the camshaft timing tool until instructed to do so.
1. Clean the groove on the camshaft housing where the camshaft housing seal is positioned.
2. Install a new camshaft housing seal into the camshaft housing.
WARNING: PERSONAL INJURY
To avoid injury when removing or installing a heavy engine component, ensure the component is
properly supported and securely attached to an adequate lifting device to prevent the component
from falling.
3. Clean the camshaft housing assembly sealing surface on the cylinder head.
NOTE: Ensure the new camshaft housing seal remains positioned in the groove before the mounting bolts are
tightened.
NOTE: The camshaft housing assembly mounting bolts will act as guides to the cylinder head.
NOTE:
On some applications it is easier to lower the camshaft housing until the bolts just contact the head, then remove
the front timing tool and position the intake gear approximately one tooth towards the center of the camshaft
housing before lowering it down completely. This will allow the gear to rotate in to the idler gear.
4. Using an appropriate lifting device, lower the camshaft housing assembly onto the cylinder head ensuring the
camshafts align properly with the camshaft timing tool.

5. Draw down the camshaft housing assembly by turning the mounting bolts gradually across the entire assembly.
NOTE: The front timing tool should slip in and out of the cams easily if they are timed correctly.
6. Verify timing of camshafts.
