Transmission.
DISASSEMBLY.
It is assumed in the detailed disassembly instructions 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 instructions; however, this assembly must also be removed from
transmission before removing unit from vehicle.
Air lines from the range shift and splitter gear controls must be disconnected at the transmission before removing unit
from vehicle.
Follow each procedure closely in each section, making use of both the text and pictures.
Carefully wash and relubricate all bearings as removed and protectively wrap until ready for use. Remove bearings with
pullers designed for this purpose.
When disassembling the various assemblies, such as the mainshaft, countershafts and shifting bar housing, lay all parts
on a clean bench in the same sequence as removed. This procedure will simplify reassembly and reduce the possibility
of losing parts.
Remove snap rings with pliers designed for this purpose. Rings removed in this manner can be reused.
The clutch or input shaft can be removed without removing the countershafts, mainshaft or drive gear.
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.
Apply force to shafts, housings, 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.
Bearing removed with chisel, damaged outer race.
