How to Install the Countershaft Assembly
Special Instructions
When installing the countershaft assemblies into the
countershaft bearings, keep the countershaft
assemblies straight. Do not cock the countershafts.
If, when the countershaft bearing cover is removed and
you can not see the snap ring groove, install the cover
and drive the countershaft further until you can see the
groove.
Make sure the synchronizer assembly springs were not
released from the HI range ring bores during bearing
installation. If the springs release, see "How to
Assemble the Synchronizer Assembly".
Special Tools
Typical service tools are needed
Vise with brass jaws or wood blocks
Bearing driver and maul
Toolmaker’s dye
Large snap ring pliers
To Assemble
1.
Place the countershaft assembly vertical on a
clean, flat surface. If previously removed, using
the proper driver and maul install the countershaft
bearing race.
2.
In the countershaft rear bearing bore, using the
proper driver and maul, install the countershaft
bearing.
3.
Temporarily install the rear bearing cover, use two
(2) capscrews and no gasket. The cover holds the
bearing as the countershaft is driven into the
bearing.
4.
Use toolmaker’s dye and mark the LO range gear
tooth with an "O" for timing purposes.
5.
Position the countershaft assemblies in the
auxiliary housing. Mesh the countershaft LO
range gear marked tooth.
6.
Center the countershaft rear in the bearing bore,
complete installation with a soft bar and maul.
