Transaxle Maintenance and Repair
Introduction
Important considerations in assembling and disassembling the transaxle for the Pack Mules and Power
Mules include cleanliness, replacement of bearings and seals, careful removal of snap rings, and the appli-
cation of adequate torque on bolts, bearings and screws. For these procedures, the proper tools are required.
Some of the service operations require special tools, e.g., oil seal, bearing and slide hammer pullers.
Wesley International recommends that original Wesley service parts be used if parts need to be replaced.
Call 800-241-2869 to order replacement parts.
All maintenance personnel should be aware that the
transaxle is a precision assembly, and as such, repair
and replacement of parts must be done with great care
in a clean environment. The following are general
recommendations that relate to working on the transaxle:
Handle all gears with extreme care.
Degrease the transaxle assembly before disassembling.
Clean parts in a small wash tank prior to assembly.
Replace bearings, seals, and O-rings if removed, regardless of hours of use.
Replace nuts used on the ring gear and brake installation during service regardless of the hours
of use.
Remove bearings and seals with special pullers.
When removing the cover plate, position the transaxle over a drain pan.
Bearing caps are marked for identifi cation. Letter or numbers are stamped in horizontal or vertical
positions. During reassembly, use caution to not damage sealing surfaces such as the housing sealing
surfaces. Snap rings must be removed or installed with care to prevent damage to bearings, seals and
bearing boxes.
Use soft, clean, lintless towels to dry components after cleaning.
Do not air dry bearings with compressed air.
Apply anti-seize compound to the axle shaft spline to prevent wear and corrosion.
Use SAE 90 wt. (ISO 220) gear oil. (The vehicle uses 12 oz. of oil when empty.) •
