General Information
Minor repairs may be performed, following the procedures
in this section, without voiding the unit warranty.
Cleanliness is a primary means of assuring satisfactory life
on either new or repaired units. Cleaning parts by using
solvent wash and air drying is usually adequate. As with
any precision equipment, all parts must be kept free of
foreign materials and chemicals.
Protect all exposed sealing surfaces and open cavities
from damage and foreign material. The outer surfaces must
be cleaned before beginning any repairs.
It is recommended that all O-rings and seals be replaced.
Lightly lubricate all O-rings and seals with a clean petro-
leum jelly prior to assembly.
Plug/Fitting Torques
If any plugs were removed during servicing, they should be
torqued as indicated in the accompanying table:
Shaft Seals
Lip type seals are used on the pump input shaft, pump
through shaft (not all models use the through shaft), motor
output shaft and displacement control shaft. These seals
can be replaced without major disassembly of the unit.
However, replacement of the seals generally requires
removal of the transmission from the machine.
To replace the pump input shaft seal, first remove the
retaining ring from the housing.
Carefully pull the seal out of the housing bore. A “hook” type
tool may be used to grasp the seal and pull it out, or a slide
hammer type puller may be used to remove the seal. Care
must be taken so as not to damage the housing bore, shaft
sealing surface, or bearing. Once removed, the seal is not
reusable.
