| (1) | Front Removal |
| (2) | Rear Removal |
Start By:
- Remove the rocker arms and the rocker shafts.
| NOTICE |
|---|
|
Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
| NOTICE |

|
Do not turn the crankshaft or the camshaft while the camshaft gear is removed. If the rear gear group is not correctly timed during installation, interference can occur between the pistons and the valves, resulting in damage to the engine. |
| NOTICE |

|
Care must be used when removing or installing the camshaft. Do not damage the finished surfaces of the camshaft or the camshaft bearings. |
- Drain the coolant from the cooling system into a suitable container for storage or disposal. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change".

Illustration 8 g01160265 - Install Tooling (A) and Tooling (B) on the rear of camshaft (15). Install Tooling (A) on the front of camshaft (15).
- Install Tooling (C) on the front housing or the rear housing. Tooling (C) is used to support the camshaft.
Note: Install Tooling (A) and Tooling (B) on the camshaft. Tooling (A) and Tooling (B) will support the camshaft as the camshaft is moved out of the cylinder head and into Tooling (C). Align the camshaft with the bore of Tooling (C).
Note: Avoid lifting the camshaft. The camshaft should rest on Tooling (A) and Tooling (B). Lifting the camshaft can lead to misalignment as the camshaft is removed, resulting in damage to the camshaft bearings.
- Carefully slide the camshaft out of the cylinder head for removal. Use two people to remove the camshaft. Keep the camshaft level while the camshaft is being removed from the cylinder head. The weight of the camshaft is approximately
35 kg (77 lb) .Note: Rotate the camshaft during removal to prevent the camshaft from binding in the camshaft bearings.
