Please Note:
The gear set used in the range of gear
boxes covered by this section may be identified
by the following characteristics. See Section CM
for a full discussion of these characteristics.
1.
Input gear utilizes slide-in needle bearing.
2.
First-speed countershaft gear is the later type with
seventeen teeth.
3.
All mainshaft gears have the later symmetrical dog teeth.
4.
Bushes inside first, second, and third gears are bronze
rather than steel; oil holes in gears do not line up with
grooves in bushes.
5.
Both synchronizer sleeves will have grooves which are
enlarged at each end to accommodate the larger
dog teeth on the mainshaft gears.
6.
Gears with a new tooth profile on their meshed teeth
were introduced in this range of gearboxes. Gears
with the new tooth profile are first, second, and fourth
mainshaft gears and first, second, and constant
gears on the countershaft.
