Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Thoroughly clean the gasket surfaces of the cylinder head and the cylinder block. Do not damage the gasket surfaces of the cylinder head or the cylinder block. Ensure that no debris enters the cylinder bores, the coolant passages, or the lubricant passages.
Inspect the gasket surface of the cylinder head for distortion. Refer to Specifications, "Cylinder Head" for more information. If the gasket surface of the cylinder head is distorted beyond maximum permitted limits, replace the cylinder head.

Inspect dowels (20) for damage. If necessary, replace the dowels in the cylinder block.
Install Tooling (B) to the cylinder block.
Align a new cylinder head gasket (21) with dowels (19). Install the new cylinder head gasket (20) onto the cylinder block.
Use a suitable lifting device to lift cylinder head. The weight of the cylinder head is approximately 96 kg (212 lb). Note: A spreader bar must be used in order to distribute the weight of the cylinder head during the lifting operation.
Use Tooling (B) to align the cylinder head with the cylinder block. Install the cylinder head to the cylinder block. Note: Ensure that the cylinder head is correctly positioned on dowels (20).
Remove Tooling (B).

Install bolts (12) to the clips for tube assembly (13). Tighten the bolts to a torque of 44 N m (32 lb ft).
Remove plugs from plastic tube assembly (6) and plastic tube assembly (8).
Remove caps from connections on fuel injection pump (7)
Connect plastic tube assembly (6) and plastic tube assembly (8) to fuel injection pump (7).
Position bracket (5) and bracket (10) onto cylinder head.
Install bolts (4) and bolts (9) to bracket (5) and bracket (10). Tighten the bolts to a torque of 22 N m (195 lb in).
Position bracket (2) onto the cylinder head. Install bolt (3) to the bracket. Tighten the bolt to a torque of 22 N m (195 lb in).
Connect the tube assembly and hose assembly from connection (11). Tighten hose the clamp securely.
If necessary, install the tube assembly from the cylinder head and the boost control on the fuel injection pump. Refer to Disassembly and Assembly, "Fuel Injection Pump- Install (With Boost Control)" for the correct procedure.
