Transaxle Reassembly
63
Before reassembling the transaxle, clean
all parts and assemblies with clean solvent
and blow them dry with compressed air. In-
spect and replace
all
scratched or damaged
parts. Replace all gaskets, seals and seal
rings. Lubricate all seals with petroleum jelly
(Vaseline) for retention during assembly.
Freely lubricate all bearings and finished part
surfaces with clean hydraulic fluid to provide
lubrication at start-up.
Dump Valve
Fitting Nut
and O-ring
Transaxle with Dump Valve
64
To reassemble the dump valve, first
lubricate and install the O-ring in the groove
located in the dump valve bracket.
65
Install the spring on the dump valve
bracket. It should be installed with the right
angle bend of the spring pointing inward,
as shown here.
66
Install the spring and dump valve
bracket in the housing.
67
The spring is properly positioned when
the longest leg points toward the check
valve assembly.
68
Lubricate and install the O-ring around
the dump valve nut.
69
Install the nut over the dump valve
bracket, into the housing.
Note:
Make sure you do not damage the
dump valve O-ring during installation.
70
Using a
1
inch socket or end wrench,
torque the dump valve nut to
150
Ib-in
[I7
Nm].

into Housing-CW into Housing-CCW
Transaxle with Charge Pump
71
Install the gerotor on the housing.
Note:
The gerotor ring and star have been
marked with a dot on each, the ring and
star can be placed with these marks up or
down but both marks should be on the
same side.
72
For easier assembly, rotate the
gerotor outer ring to fully engage with the
inner star. The fully engaged side of the
gerotor should point towards the designed
input rotation (CW or CCW as noted on
the housing).
Note:
The designed input rotation is
stamped on the back side of the housing
and also next to the gerotor on the inside.
73
Freely lubricate the gerotor with clean
hydraulic fluid to provide lubrication at
start-up.
74
The charge pump plate has a small
arrow cast into the outer face of the plate.
