DISASSEMBLY
It is assumed in the detailed disassembly instruc-
tions that the lubricant has been drained from the
transmission, the necessary linkage and air lines
removed and the transmission has been removed
from the chassis. Removal of the gear shift lever
housing assembly is included in the detailed in-
structions; however, this assembly must also be
removed from transmission before removing unit
from vehicle.
Follow each procedure closely in each section,
making use of both the text and pictures.
1. BEARINGS - Carefully wash and relubricate all
bearings as removed and protectively wrap until
ready for use. Remove bearings with pullers de-
signed for this purpose.
2. ASSEMBLIES - When disassembling the
various assemblies, such as the mains shaft,
countershafts and shifting bar housing, lay all parts
on a clean bench in the same sequence as removed.
This procedure will simplify re-assembly and
reduce the possibility of losing parts.
3. SNAP RINGS - Remove snap rings with pliers
designed for this purpose. Rings removed in this
manner can be reused.
4. INPUT SHAFT - The input shaft can be removed
without removing the countershafts, mainshaft or
drive gear.
5. CLEANLINESS - Provide a clean place to work.
It is important that no dirt or foreign material enters
the unit during repairs. The outside of the unit
should be carefully cleaned before starting the
disassembly. Dirt is abrasive and can damage
bearings.
6. WHEN DRIVING - Apply force to shafts, hous-
ings, etc., with restraint. Movement of some parts is
restricted. Do not apply force after the part being
driven stops solidly. Use soft hammers and bars for
all disassembly work.
INSPECTION
Before reassembling the transmission, the individ-
ual parts should be carefully checked to eliminate
those damaged from previous service. This inspec-
tion procedure should be carefully followed to in-
sure the maximum of wear life from the rebuilt unit.
The cost of a new part is generally a small frac-
tion of the total cost of downtime and labor, should
the use of a questionable part make additional re-
pairs necessary before the next regularly scheduled
overhaul.
Recommended inspection procedures are set
forth in the following check list:
