Removal / Disassembly
Remove Gear and Cam Pins
1. Remove gear locknut. Use deep-well socket while
holding shaft end with locking pliers.
2. Remove ground lead wire.
3. Lift shaft and gear assembly out of housing.
Note: The cam pins are removed from the gear side of hous-
ing. Do not disturb the switch spring.
4. Remove cam pins from housing.
Cleaning
After shift unit disassembly, clean all parts (with exception of
the motor and circuit board), in a suitable commercial solvent.
Dry with clean, lint-free cloth or compressed air before lubri-
cating or reassembly.
Make sure all residual gasket compound is removed from
mating surfaces.
WARNING: Gasoline is not an acceptable solvent because
of its extreme combustibility. It is unsafe in the workshop
environment.
Lubrication
Lubrication of the shift unit is not required except when unit
has been disassembled. Instructions are contained in the shift
unit assembly procedures in this manual.
Note: Use only “Rheolube 362” for shift lubrication. Use of
other lube types may cause shift unit operational prob-
lems under certain low temperature conditions. A tube
of this lubricant is included in Spicer Shift Unit Service
Kits. It can also be purchased separately under Part
No. 113741.
Sealing
CAUTION: Use approved gasket compound (Part No.
113771) to seal shift unit cover and other components.
Standard RTV sealant may cause corrosion of electrical
components.
Proper sealing of the shift unit mating surfaces is essential for
long life and trouble-free operation. For effective sealing, use
approved gasket compound. During reassembly, make sure
the mating surfaces are clean and that the compound pattern
is not disturbed. Also, the gasket compound will set in 20
minutes. Assemble components before compound sets or
reapply.
