CLUTCH HOUSING
DIAGNOSIS AND TESTING - CLUTCH HOUSING
Clutch housing alignment is important to proper
clutch operation. The housing maintains alignment
between the crankshaft and transmission input
shaft. Misalignment can cause clutch noise, hard
shifting, incomplete release and chatter. It can also
result in premature wear of the pilot bearing, cover
release fingers and clutch disc. In severe cases, mis-
alignment can also cause premature wear of the
transmission input shaft and front bearing.
Housing misalignment is generally caused by
incorrect seating on the engine or transmission, loose
housing bolts, missing alignment dowels, or housing
damage. Infrequently, misalignment may also be
caused by housing mounting surfaces that are not
completely parallel. Misalignment can be corrected
with shims.
CHECKING RUNOUT
Only the NV4500 clutch housing can be
checked using the following bore and face
runout procedures. The NV3500 and NV5600
clutch housings are an integral part of the
transmission and can only be checked off the
vehicle.
MEASURING CLUTCH HOUSING BORE RUNOUT
(1) Remove the clutch housing and strut.
(2) Remove the clutch cover and disc.
(3) Replace one of the flywheel bolts with an
appropriate size threaded rod that is 10 in. (25.4 cm)
long (Fig. 14). The rod will be used to mount the dial
indicator.(4) Remove the release fork from the clutch hous-
ing.
(5) Reinstall the clutch housing. Tighten the hous-
ing bolts nearest the alignment dowels first.
(6) Mount the dial indicator on the threaded rod
and position the indicator plunger on the surface of
the clutch housing bore (Fig. 15).
(7) Rotate the crankshaft until the indicator
plunger is at the top center of the housing bore. Zero
the indicator at this point.
(8) Rotate the crankshaft and record the indicator
readings at eight points (45É apart) around the bore
(Fig. 15). Repeat the measurement at least twice for
accuracy.
(9) Subtract each reading from the one 180É oppo-
site to determine magnitude and direction of runout.
Refer to (Fig. 16) and following example.
Bore runout example:
0.000 ± (±0.007) = 0.007 in.
+0.002 ± (±0.010) = 0.012 in.
+0.004 ± (±0.005) = 0.009 in.
±0.001 ± (+0.001) = ±0.002 in. (= 0.002 inch)
In the above example, the largest difference is
0.012 in. and is called the total indicator reading
(TIR). This means that the housing bore is offset
from the crankshaft centerline by 0.006 in. (which is
1/2 of 0.012 in.).

MANUAL - NV3500
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 transmission has a single shaft shift mecha-
nism 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

SECOND 2.32:1
THIRD 1.40:1
FOURTH 1:1
FIFTH 0.73:1
REVERSE 3.55:1
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.

MANUAL - NV5600
DESCRIPTION
The NV5600 is a six speed constant mesh manual
transmission (Fig. 1). All gear ranges including
reverse are synchronized. First and second gears uti-
lize dual cone synchronizers in order to aid shifting.Sixth gear is an overdrive range. The transmission
uses cast iron for the gear case and extension/
adapter housing and aluminum for the clutch hous-
ing.
The transmission is a end loader transmission. The
shift lever is located in a shifter tower which is
bolted to the gear case and operates the shift shaft.

IDENTIFICATION
The transmission has two identification tags
attached to the driver side upper clutch housing (Fig.
3).
One tag provides the transmission part number.
The second tag provides sequencing and build date
information. The information on the tags are essen-
tial to correct parts ordering.
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.The driver selects a particular gear by moving the
shift lever to the desired gear position. This move-
ment moves the internal transmission shift compo-
nents to begin the shift sequence. As the shift lever
moves the selected shift rail, the shift fork attached
to that rail begins to move. The fork is positioned in
a groove in the outer circumference of the synchro-
nizer sleeve. As the shift fork moves the synchronizer
sleeve, the synchronizer begins to speed-up or slow
down the selected gear (depending on whether we are
up-shifting or down-shifting). The synchronizer does
this by having the synchronizer hub splined to the
mainshaft, or the countershaft in some cases, and
moving the blocker ring into contact with the gear's
friction cone. As the blocker ring and friction cone
come together, the gear speed is brought up or down
to the speed of the synchronizer. As the two speeds
match, the splines on the inside of the synchronizer
sleeve become aligned with the teeth on the blocker
ring and the friction cone and eventually will slide
over the teeth, locking the gear to the mainshaft, or
countershaft, through the synchronizer.
DIAGNOSIS AND TESTING - MANUAL
TRANSMISSION
LOW LUBRICANT LEVEL
A low transmission lubricant level is generally the
result of a leak, inadequate lubricant fill or an incor-
rect lubricant level check.
Leaks can occur at the mating surfaces of the gear
case, adaptor or extension housing, or from the front/
rear seals. A suspected leak could also be the result
of an overfill condition.
Leaks at the rear of the extension or adapter hous-
ing will be from the housing oil seals. Leaks at com-
ponent mating surfaces will probably be the result of
inadequate sealer, gaps in the sealer, incorrect bolt
tightening or use of a non-recommended sealer.

Fig. 3 Identification Tag Location

BR/BEMANUAL - NV5600 21 - 93
MANUAL - NV5600 (Continued)

A leak at the front of the transmission will be from
either the front bearing retainer or retainer seal.
Lubricant may be seen dripping from the clutch
housing after extended operation. If the leak is
severe, it may also contaminate the clutch disc caus-
ing the disc to slip, grab and or chatter.
A correct lubricant level check can only be made
when the vehicle is level. Also allow the lubricant to
settle for a minute or so before checking. These rec-
ommendations will ensure an accurate check and
avoid an underfill or overfill condition. Always check
the lubricant level after any addition of fluid to avoid
an incorrect lubricant level condition.
HARD SHIFTING
Hard shifting is usually caused by a low lubricant
level, improper or contaminated lubricants. The con-
sequence of using non-recommended lubricants is
noise, excessive wear, internal bind and hard shift-
ing. Substantial lubricant leaks can result in gear,
shift rail, synchro, and bearing damage. If a leak
goes undetected for an extended period, the first indi-
cations of component damage are usually hard shift-
ing and noise.
Component damage, incorrect clutch adjustment or
damaged clutch pressure plate or disc are additional
probable causes of increased shift effort. Incorrect
adjustment or a worn/damaged pressure plate or disc
can cause incorrect release. If clutch problem is
advanced, gear clash during shifts can result. Worn
or damaged synchro rings can cause gear clash when
shifting into any forward gear. In some new or
rebuilt transmissions, new synchro rings may tend to
stick slightly causing hard or noisy shifts. In most
cases this condition will decline as the rings wear-in.
TRANSMISSION NOISE
Most manual transmissions make some noise dur-
ing normal operation. Rotating gears generate a mild
whine that is audible, but generally only at extreme
speeds.
Severe highly audible transmission noise is gener-
ally the initial indicator of a lubricant problem.
Insufficient, improper or contaminated lubricant will
promote rapid wear of gears, synchros, shift rails,
forks and bearings. The overheating caused by a
lubricant problem, can also lead to gear breakage.
