Slip the head and rotor assembly, drive end up, into the hold-
ing fixture. Place the six governor weights (1, figure 8-8) in
their sockets with the slots facing the bore of the assembly.
Place the thrust sleeve washer (3, figure 8-8) against the
thrust sleeve (2, figure 8-8) so that the chambered edge faces
the sleeve. Insert the forefinger into the bore of the sleeve
and washer, holding them together, and insert them into the
slots of the governor weights by tilting the weights slightly
back. The two slots on the thrust sleeve flange should face
up. Sight across the tops of the assembled weights to ascer-
tain correct positioning. One weight higher than others indi-
cates incorrect assembly of the thrust washer.
Place the governor arm (7, figure 8-9) in position with the
fork for the governor linkage hook facing the end plate. In-
sert pivot shaft (3, figure 8-9) with the knife edge facing the
end plate and assemble the two seals (2, figure 8-9) and nuts
(1, figure 8-9). Tighten the nuts simultaneously to a torque
of 20 to 25 inch-pounds.
Rotate the cam ring so that the unthreaded hole is in line with
the metering valve bore to insure proper positioning of the cam.
Apply a light film of clean grease around the inside edge of the
Do not force. If the hydraulic head
should cock during insertion, withdraw

Grasp the hydraulic head firmly in both hands and insert it
into the housing with a slight rotary motion.
Make sure that the assembly is put
into position past the hydraulic
head seal (11, figure 8-11). Fail-

Rotate the hydraulic head until the head locking screw holes
are aligned. Install head locking screws (8, figure 8-12) fin-
Invert the pump and holding fixture in the vise so that the
bottom faces up.
Install seals (16, figure 8-10) and head locating screw (15,
