Use care not to cock blades during installation, as sharp edge on liner (15) can score blade ends.
Assemble springs (14) to blades (13) and install blades in their slots in rotor. Blade springs (14) must be fully
compressed as they are installed.
Assemble transfer pump components as follows:
If necessary, install new spring pin (12) in correct hole in regulator (8) for clockwise rotation. On face of
regulator 'C' is stamped for clockwise pump operation.
Using small flat screwdriver, install new piston seal (11) in groove of regulator (8). Do not roll seal over when
To prevent excessive transfer pump pressure and damage to pump when it is operated, ensure
adjusting plug (7) is flush with end of regulator.
Install piston (9) in the regulator with hollow end facing spring or threaded end of bore. Install spring (10) and
adjusting plug (7). The plug contains a viscosity compensating orifice and should be installed so top of screw
is flush with end of regulator assembly.
Using O-ring pick, check piston for freedom of movement in its bore.
Coat beveled surfaces on strainer base with general purpose grease (630AA).
Install element strainer (6) onto transfer pump regulator assembly.
Coat 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 (81, FIGURE 3-64) to link hook (46) with screw (79) and washer (80).
If disconnected, connect spring (47) to governor arm (44) and linkage hook assembly (46).
If drive shaft (42, FIGURE 3-73) was removed after installation, seals and bearing must be replaced.
Install drive shaft (42), seals (44 and 45), bearing (46), and thrust components (38, 39, 40, and 41) as follows:
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.
Place new fuel seal (44) on seal/bearing installation tool (28316) (end opposite removable collar) with open
side of seal facing outward, refer to FIGURE 3-92.
