Now that the transmission has been completely disassembled, wash all parts in gasoline. Check all parts to be sure that they are in good condition. Oil bearings and check them for wear, cracked balls or roughness.
All worn or damaged parts should be replaced. Bushings The bushings used in the counter, idler and second speed gears are pressed into these parts and accurately bored with special diamond boring tools. This insures the positive alignment of these bushings and their shafts as well as the proper mesh of the gears.
Because of the high degree of accuracy to which these parts are
machined, they will not be serviced separately and can be purchased
as part of the gear assembly.
In checking these bushings for wear a new shaft should be used.
The proper clearance between the gears and their shafts should
be from .002" to .004". A narrow feeler gauge of the
proper thickness can be used to accurately check these bushings
for their proper clearance.
Reassembly of Transmission
In reassembling the transmission it is very important that factory
limits and clearances be maintained and cleanliness observed.

It is good practice to first put together the sub-assemblies that
are a part of the transmission, so that all arbor press work is
completed before going to the bench for re-assembling of the unit.
Assemble the rear spline shaft bearing to the universal joint ball
retainer with the oil seal towards the transmission side. See Fig.
115. Assemble oil sleeve and bearing lock to the universal joint
ball retainer, making sure that the lock is seated in the machined
groove in the retainer.
long shank wrench. Then remove the universal joint front yoke with
the front ring and trunnions bearings on it.
Remove the cap screws from the universal joint ball retainer and
turn the retainer so that it will clear the countershaft.
Drive out the countershaft from the REAR to the FRONT. This allows
the counter gear to drop into the bottom so that the second speed
gear can be removed.
Remove the universal joint ball retainer with the second speed
gear and clutch sleeve assembled to it. Remove the first speed
gear, spline shaft pilot bearing, the front synchronizing drum
and spring through the upper hole on the transmission case.
Fig. 114— Synchronizing Spring Tool
Remove the main drive gear bearing retainer screws and then remove
the main drive gear with the bearing from the case. Drive out the
idler gear expansion plugs, remove the idler gear shaft lock screw
and drive out the idler gear shaft from the FRONT to the REAR of
the transmission case and remove the idler gear from the case.
Remove the counter gear and thrust washers from the case. Remove
the clutch sleeve from the spline shaft and press out the spline
shaft from the transmission rear bearing. Remove the lock holding
the rear bearing to the universal joint ball retainer and remove
the bearing.
Remove the second speed gear and thrust washer from the spline
shaft. Remove the synchronizing spring, with the special tool shown
in Fig. 114, from the spline shaft. Remove the second speed gear
synchronizing drum, thrust washer retainer and thrust washer from
the spline shaft.
Remove the lock holding the main drive gear bearing to the main
drive gear and press the bearing from the gear with the special
press plates in an arbor press.
