ASSEMBLY
(1) Lubricate gear bore in pump housing with
transmission fluid.
(2) Lubricate pump gears with transmission fluid.
(3) Support pump housing on wood blocks (Fig.
179).
(4) Install outer gear in pump housing (Fig. 179).
Gear can be installed either way (it is not a one-way
fit).
(5) Install pump inner gear (Fig. 180).
CAUTION: The pump inner gear is a one way fit.
The bore on one side of the gear inside diameter (I.
D.) is chamfered. Be sure the chamfered side faces
forward (to front of pump).

Lubricate seal rings with transmission fluid or petro-
leum jelly after installation. Squeeze each ring until
ring ends are securely hooked together.
CAUTION: The reaction shaft support seal rings
will break if overspread, or twisted. If new rings are
being installed, spread them only enough for instal-
lation. Also be very sure the ring ends are securely
hooked together after installation. Otherwise, the
rings will either prevent pump installation, or break
during installation.
(8) Install reaction shaft support on pump housing
(Fig. 182).
(9) Align reaction support on pump housing. Use
alignment marks made at disassembly. Or, rotate
support until bolt holes in support and pump housing
are all aligned (holes are offset for one-way fit).
