Illustration 3 g01094447
Improper assembly of parts that are spring loaded can cause bodily injury.To prevent possible injury, follow the established assembly procedure and wear protective equipment.
Install spring seat (11) and the spring.
Illustration 4 g01094444
Install yoke (15) inside the housing of the pump group.
Illustration 5 g01096191
Install plug (13). Tighten the plug to a torque of 7.45 0.65 N m (65.938 5.753 lb in).
Use Tooling (G), Tooling (H), and a suitable press in order to install pintle bearing (14). The bearing that is located on the same side of the housing as spring seat (11) should be installed first.
Ensure that the outer race of pintle bearing (14) is started in the housing on the side opposite of the spring.
Lightly lubricate the yoke with clean engine oil. Ensure that the yoke is in the correct position. The bearings will hold the yoke in place when the bearings are installed.
Use Tooling (G) and a suitable press in order to install the second bearing in the housing.
Ensure that the yoke moves freely before you proceed with the assembly procedure.
Install O-ring seal (12).
Illustration 6 g01094431
Install covers (10).
Install bolts (9). Tighten bolts (9) to a torque of 20 1 N m (15 1 lb ft).
Illustration 7 g01196942
Use the coupling from the fuel transfer pump and Tooling (J) in order to install shaft (8) back into the proper position.
Illustration 8 g01094422
Install rotating group (7) by using the following procedure.
Position the housing so that the internal end of the shaft is angled downward.
Slide rotating group (7) over the shaft and into the housing. Ensure that the shoes of rotating group (7) are against the yoke.
Illustration 9 g01094836
Once the rotating group is installed, turn the rotating group in order to ensure that pins (23) are still in the special notches. If the rotating group jams, pins (23) need to be reinserted into the proper position. The pins in the rotating group are held in position with a “C” clip. See Illustration 9.
Illustration 10 g01094416
Lightly lubricate the face of valve block (3) with clean engine oil. Position control piston (6) on the control shaft.
Install gasket (5).
Illustration 11 g01094839
Install valve block (3) by using the following procedure.
Place a finger over large middle hole (24) on the mounting surface of valve block (3) in order to create a vacuum. This will hold the control piston in place while you install valve block (3).
Ensure that the housing gasket is not damaged. Align valve block (3) with the pins that are in the housing of the pump group.
Illustration 12 g01094410
Start bolts (4) in valve block (3) by hand.
Tighten bolts (4) by alternating from all four sides. Tighten the bolts in the corners first. Tighten the bolts to a torque of 28 3 N m (20 2 lb ft).
Install manifold (2).
Install pressure compensator valve (1).
Illustration 13 g01094450
Install shaft seal (18) by using the following procedure.
Lightly lubricate the shaft seal with clean engine oil.
Use Tooling (E) to lower shaft seal (18) below the edge of the bore.
Position retaining ring (19) against the shaft seal below the edge of the bore.
