(11) Rotating Group. (15) Shaft.
Install the rotating group (11) .

(34) Pins
Once the rotating group is installed, turn the rotating group in order to ensure that the three pins (34) are still in the special notches. If the rotating group jams, the pins (34) need to be reinserted into the proper position. The three pins in the rotating group are held in the special notches with a "C" clip retaining ring. The "C" clip applies force against the inside diameter of the rotating group's cylinder block in order to hold the pins in position. See Illustration 32.

(7) Valve Block. (9) Housing Gasket. (35) Large Middle Hole.
Install the housing gasket (9) .
Moderately oil the face of the valve block (7) with clean engine oil. Place the control piston onto the control shaft.
Install the valve block (7) .
Place a finger over the large middle hole (35) in the mounting surface of the valve block (7) in order to create a vacuum. This will hold the control piston in place while you are installing the valve block (7) .
Ensure that the housing gasket (9) is not damaged while you are aligning the valve block (7) to the pins in the pump housing.

(25) Shaft Seal. (36) FT-2608 Bearing Installation Tool .Note: Step 20 through Step 22 defines the procedure for the installation of the shaft seal. These steps should be followed precisely. The shaft seal should be placed barely below the face of the housing. The snap ring should then be positioned against the seal. Both the snap ring and the seal should be driven into the bore together until the snap ring seats in the groove.
Use the FT-2608 Bearing Installation Tool (36) to lower the shaft seal (25) below the edge of the bore.
Place the snap ring against the shaft seal below the edge of the bore.
