TRANSMISSION
Description (3-Speed Transmission). The sturdy synchro-mesh
transmission with steering column gear shift control used as
standard equipment on the
1f2
and
% ton models provides
three forward speeds and reverse. It is of helical gear type
providing unusually quiet operation in all gears.
The gears are carburized and shot peened for additional
strength and long life. The countergear is mounted on needle
bearings. The clutch gear is supported by a heavy duty ball
bearing at the front end of the transmission case. The front
end of the mainshaft is supported by two sets of needle pilot
bearings in the hollow end of the clutch gear and the rear end
is carried by a ball bearing mounted
in
the rear of the trans-
mission case.
Description (Heavy-Duty 3-Speed Transmission). A heavy-
duty 3-speed transmission, which incorporates greater gear
reductions and more rugged construction than the standard
3-speed transmission, is available as optional equipment On
.-
1f2
and
%
ton truck models; also on 1 ton truck models where
heavy duty applications do not require a 4-speed transmission.
This transmission features wider gears with greater contact area,
heavier mainshaft support bearings, larger double row roller
countershaft bearings, and gear ratios better suited to truck
operation.
Description (4-Speed Transmission). This sturdy synchro-mesh
transmission has increased durability and has synchro-mesh
action into second, third and fourth speeds using helical gears,
affording quieter operation and longer life.
