Always install the seal plates after the cylinder liners are installed. Aluminum debris shaved from the plates by the cylinder liners will prevent the cylinder liners from sealing if the plates are installed first.
Note: Steps 6 through 10 are for engines that are equipped with flange cooled cylinder liners.

Attach Tooling (C) and a suitable lifting device to cylinder head (10). The weight of cylinder head (10) is approximately 204 kg (450 lb).
Carefully lower cylinder head (10) onto the cylinder head studs. While the cylinder head is being lowered, reach through the side opening and hold rod assembly (4) so that the rod assembly does not interfere with the cylinder head assembly.
Be sure that the cylinder head assembly is seated on the dowels and be sure that the seal plates and the O-ring seals are seated properly.
Install the nuts and the washers in order to hold the cylinder head. Tighten the nuts by hand. Note: Lubricate the washer face and the threads of the cylinder head studs with Tooling (F) before assembly.

Install Tooling (A) over the nuts, and attach Tooling (B) to Tooling (A).
Tighten collars (6) with a ratchet lever (1/2 inch drive). Loosen the collars for 1/4 turn.
Personal injury can result from oil under high pressure.DO NOT allow high pressure oil to contact skin.Wear appropriate protective equipment while working with high pressure oil systems.
Note: The stud tensioner tool groups in Tooling (A) require different operating pressure.
Run the pump in Tooling (B) until the operating pressure is registered on the gauge.
Place dowel handle (7) through the slot in each pedestal in
