The plug contains a viscosity compensating orifice and should be installed so top of screw is
flush with end of regulator assembly.
Install piston (9) in the regulator with hollow end facing spring or threaded end of bore. Install spring (10)
and adjusting plug (7).
Using O-ring pick, check piston for freedom of movement in its bore.
Install assembled regulator on liner (15). Coat beveled surface on element strainer base (6) with general
purpose grease (630AA).
Install element strainer (6) onto transfer pump regulator assembly.
Coat beveled surface and threads on OD of end cap (5) with general purpose grease (630AA).
Install end cap (5) and thread into hydraulic head by applying a slight pressure on top of end cap. Rotate end
cap counterclockwise until a slight click is heard, then turn cap clockwise by hand until tight.
If disassembled, attach link assembly (76, FIGURE 3-45) to link hook (46) with screw (74) and washer (75).
If disconnected, connect spring (47) to governor arm (44) and linkage hook assembly (46).
Install drive shaft (41, FIGURE 3-52), seals (40), thrust washer (39), spring washer (38), and retaining ring (37)
Extreme care must be used when Installing seals or leaks will result from distortion and/or
damage to teflon sealing element. Calibration oil may be used to facilitate seal Installation.
Apply a light coat of general purpose grease (630AA) to seals (40).
Install seals (40) on shaft (41).
Do not Invert drive shaft seals (40) when Installing drive shaft (41). If resistance Is felt, stop and
Inspect seal. If seal was forced back, stop and replace seal.
Before installing shaft (41), find small drilled hole (off-center) on drive shaft tang. There is a
similar hole drilled in the distributor rotor. When installed, the drive shaft and distributor rotor
holes must be aligned.
Compress seals (40) and install drive shaft (41) in pump housing.
Slide thrust washer (39), aligned with flat, and then spring washer (38) onto drive shaft. Secure with
retaining ring (37).
Place governor arm (44, FIGURE 3-45) into position in housing. Insert governor shaft (73) through hole in
housing so knife edge mates with groove in governor arm, refer to FIGURE 3-75.
