GENERAL SERVICE
PRECAUTIONS
When servicing the transmission, it is recommended that
upon disassembly of a unit, all parts should be cleaned and
inspected
as
outlined
under
CLEANING
AND
INSPECTION. The unit should be reassembled before
disassembly of other units to avoid confusion and
interchanging of parts.
1. Before disassembly of the unit, thoroughly clean the
exterior.
2.
Disassembly and reassembly of the unit and tie
subassemblies must be made on a clean work bench. As in
reparing any hydraulically operated unit, cleanliness is of the
utmost importance; therefore, the bench, tools, and parts
must be kept clean at all times.
3. Before installing cap screws into aluminum parts,
ALWAYS DIP SCREWS INTO OIL to prevent cap screws
from galling the aluminum threads and also to prevent the
screw for seizing.
4. Always use a torque wrench when installing cap
screws into aluminum parts to prevent the possibility of
stripping the threads.
5. If tapped, threads in aluminum parts are stripped or
damaged, the part can be made serviceable by the use of Heli-
Coils or equivalent.
6. Seal protecting tools must be used when assembling
the units to prevent damage to the seals. The slightest flaw
in the sealing surface of the seal can cause an oil leak.
7. The aluminum castings and the valve parts are very
susceptible to nicks, burrs, etc., and care should be exercised
when handling them.
8. The internal snap rings should be expanded and the
external snap rings compressed if they are to be reused. This
will insure proper seating when installed.
9. Replace all "0" rings, gaskets and oil seals that are
removed.
NOTE: Teflon oil seal rings should not be removed
unless damaged.
10. During assembly of each unit, all internal parts must
be lubricated with oil.
PARTS CLEANING AND INSPECTION
After complete disassembly of a unit, all metal parts
should be washed in a clean solvent and dried with
compressed air. All oil passages should be blown out and
checked to make sure that they are not obstructed. Small
passages should be checked with tag wire. All parts should
be inspected to determine which parts are to be replaced.
The various inspections of parts are as follows:
1. Inspect linkage and pivot points for excessive wear.
