Precautions
Assemble
Make sure that case interiors and housings are clean. It is important that
dirt and other foreign materials are kept out of the transmission during
assembly. Dirt is an abrasive and can damage polished surfaces of
bearings and washers. Use certain precautions, as listed below, during
assemble.
Axial Clearances
Maintain original axial clearances of .006" to .015" for mainshaft
gears.
Bearings
Use a flange-end bearing driver for bearing installation. These
special drivers apply equal force to both bearing races, preventing
damage to balls/rollers and races while maintaining correct
bearing alignment with bore and shaft. Avoid using a tubular or
sleeve-type driver, whenever possible, as force is applied to only
one of the bearing races.
Capscrews
To prevent oil leakage and loosening, use Eaton/Fuller sealant
#71211 or equivalant on all capscrews. For torque ratings, use the
torque recommendations through out the service manual.
Gaskets
Use new gaskets throughout the transmission as it is being rebuilt.
Make sure all gaskets are installed. An omission of any gasket can
result in oil leakage or misalignment of bearing covers.
Initial Lubrication
Coat all limit washers and shaft splines with Lubriplate during
assembly to prevent scoring and galling of such parts.
O-Rings
Lubricate all O-rings with silicon lubricant.
Universal Joint Companion Flange or Yoke
Pull the companion flange or yoke tightly into place with the output
shaft nut, using 450-500 Lb
f
·ft of torque. Make sure the
speedometer drive gear or a replacement spacer of the same width
has been installed. Failure to pull the companion flange or yoke
tightly into place can result in damage to the mainshaft rear
bearing.
IMPORTANT: See the appropriate Illustrated Parts Lists (specified by
model series) to ensure that proper parts are used during assemby of the
transmission.
