Installation

Perparing the fuel injection pump

If the fuel injection pump is equipped with a mechanical governor, it must be removed. GAC

recommends that this modicication be performed by a qualified fuel injection service facility. The

following procedure lists the general steps required to remove the mechanical governor.

Note :

Be prepared to collect the oil that will be released from the mechanical governor.

1. Remove the rear housing from the mechanical governor and disconnect the governor linkage

from the fuel rack. Remove the flyweight assembly. A specical tool is required.

2. Remove the intermediate governor housing. This leaves only the rack and camshaft protruding

from the pump.

3. Install the camshaft bearing retainer plate to provide support to the bearing formerly held by the

governor housing.

This plate must have countersunk holes for the mounting screws.

Installing the actuator

All hardware needed to attach the actuator to the pump is located in kit KT288 supplied with the

actuator.

1. The mounting surface on the pump must be clean. Attach the link(1) to the left-hand side of the

fuel rack with a M5 X 10 mm screw(2) that includes a patch of locking adgesive.

Tighten the screw to 3 - 4 NM so that the pump and torque to 5 - 6 NM.

2. Remove the two lower screws of the bearing retainer plate and replace them with the retainers(3).

Attach the retainers with their shorter end threaded into the pump and torque to 5 - 6 NM.

3. Temporarily place the actuator over the rack and retainers and onto the pump face. Check that

the actuator contacts both the pump face and shoulders of the retainers. If necessary, use M6

spring washers to shim the retainers. The upper and lower mounting points of the actuator must

be equally supported. Remove the actuator from the pump.
