DESCRIPTION
The NV3500 is a medium-duty, 5-speed, constant
mesh, fully synchronized manual transmission. Fifth
gear is an overdrive range with a ratio of 0.73:1. The
NV3500 is available in two and four–wheel drive con-
figurations.
The transmission gear case consists of two alumi-
num housings (Fig. 1). The clutch housing is not a
removable component. It is an integral part of the
transmission front housing.
A combination of roller and ball bearings are used
to support the transmission shafts in the two hous-
ings. The transmission gears all rotate on caged type
needle bearings. A roller bearing is used between the
input and output shaft.

The NV3500 has a single shaft shift mechanism
with three shift forks all mounted on the shaft. The
shaft is supported in the front and rear housings by
bushings and one linear ball bearing. Internal shift
components consist of the forks, shaft, shift lever
socket, and detent components (Fig. 2).
Two versions of the NV3500 are available a wide
ratio and a close ratio version.

OPERATION
The manual transmission receives power through
the clutch assembly from the engine. The clutch disc
is splined to the transmission input shaft and is
turned at engine speed at all times that the clutch is
engaged. The input shaft is connected to the trans-
mission countershaft through the mesh of fourth
speed gear on the input shaft and the fourth counter-
shaft gear. At this point, all the transmission gears
are spinning.
