REASSEMBLY.
Make sure that interiors of case and housing are clean.
It is important that dirt be kept out of transmission during
reassembly. Dirt is abrasive and can damage polished
surfaces of bearings and washers.
Use certain
precautions, as listed below, during reassembly.
1. GASKETS Use new gaskets throughout the
transmission as it is being
rebuilt.. Make sure all gaskets
are installed, as omission of
gasket can result in oil leakage
or misalignment of bearing
covers.
See "Location" of
Gaskets heading.
2. CAPSCREWS - To prevent oil leakage, use shellac
on all capscrews. See torque rating chart for
recommended torque.
3. O-RINGS - Lubricate all O-rings with "Dow Corning
200 Fluid," 50,000 cs.
4. ASSEMBLY - Refer to the disassembly illustrations
as a guide to reassembly.
5. INITIAL LUBRICATION - Coat all thrust washers
and splines of shafts with Lubriplate during
installation to provide initial lubrication, preventing
scoring and galling.
6. AXIAL CLEARANCES-Maintain original axial
clearances of mainshaft forward speed gears of
.005" to .011". Mainshaft reverse gear clearance is
.011" to .032".
7. BEARINGS - Use of flanged-end bearing drivers is
recommended
for
the
installation of bearings. These
drivers apply equal force to both
races of bearings, preventing
damage to balls and races and
maintaining correct bearing
alignment with shaft and bore.
If tubular or sleeve type driver is
used, apply force only to inner
race.
8. UNIVERSAL JOINT COMPANION FLANGE - Pull
the companion flange tightly into place with the
mainshaft nut, using 450-500 foot-pounds of torque.
Make sure the speedometer gear has been installed
on yoke. If a speedometer gear is not used, a
replacment spacer of the same width must be used.
Failure to pull the yoke or flange tightly into place
will permit the shaft to move axially with resultant
damage to rear bearing.
