Complete Disassembly
The following procedures describe complete disassembly of the Transaxle Series
dures cover the basic unit only. However, procedures
for units with options such as the differential lock/
parking brake are still basically the same.
The level of cleanliness maintained while repairing
the transaxle could affect its performance. Work in a
clean area. After disassembly, wash
clean solvent and blow the parts dry with air. Inspect
750.
These proce-
all
parts with
all mating surfaces. Replace any damaged parts
that could cause internal leakage. Do not use grit
paper, files or grinders on finished parts.
Our service policy is to replace all seals and gaskets
whenever a transaxle is disassembled. Lubricate the
new seals with petroleum jelly before installation.
Use only clean, recommended hydraulic fluid on the
finished surfaces at reassembly.
Hex Flange Screw Reservoir Adapter
Valve Cover
1
Drain the transaxle and then secure it with the
valve cover in the up position. Remove the hex
flange screws from the valve cover.
2
Remove the valve cover from the housing
assembly.
3
Remove the valve cover gasket.
Note:
The gasket may have remained on the valve
cover when the cover was removed from the housing
assembly.
Transaxle with
4
It is easier to disassemble the axle assemblies
with the transaxle as shown. Before securing the
transaxle in this position, place a clean towel
between the valve cover surface and the work
surface to protect the sealing surface from possible
damage during repositioning.
6
Use a
to 8 inch C-clamp to secure the transaxle to
a clean work surface. Do not overtighten the Cclamp when securing the transaxle.
