To Remove
1.
To keep the mainshaft pilot from falling out of the
input shaft pocket, temporarily install the
auxiliary drive gear on the mainshaft.
2.
From each countershaft rear groove, remove the
snap ring.
3.
From inside the case, use a soft bar and maul to
drive the countershaft rear bearings from the
case bores.
4.
From the each countershaft front, remove the
capscrew and front retainer plate.
5.
Use the soft bar and maul to drive each
countershaft to the rear as far as possible. This
partially unseats the front bearings.
6.
Return to the case rear, and drive each
countershaft forward as far as possible. This
exposes the bearing snap rings.
7.
Use a bearing puller or pry bars to remove the
countershaft front bearings.
