DESCRIPTION
The NV4500 is a five speed constant mesh manual
transmission (Fig. 1). All gear ranges including
reverse are synchronized. Fifth gear is an overdrive
range. The transmission has a cast iron gear case
and aluminum shift cover.
Two versions are used, a standard duty for 5.9L
applications and a heavy duty for V10 and Cummins
diesel applications. Main differences are the larger
diameter input shaft, output shaft and mainshaft
fifth gear in the heavy duty model.
Tapered roller bearings support the drive gear,
mainshaft and countershaft in the gear case. Roller
bearings in the drive gear support the forward end ofthe mainshaft. The mainshaft gears are all supported
on caged type roller bearings. Drive gear thrust reac-
tion is controlled by a needle type thrust bearing.
The bearing is located at the forward end of the
mainshaft.
The transmission is a top loader style. The shift
lever is located in a shifter tower which is bolted to
the shift cover and operates the shift forks and rails
directly. The shift forks and rails are all located
within the aluminum cover which is bolted to the top
of the gear case.
SHIFT PATTERN
The shift pattern is in a modified H pattern (Fig.
2). Overdrive fifth and reverse gears are in line and
outboard of the first through fourth gear positions.

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.
To drain the trans remove the bottom PTO cover
bolt. Fill the trans through the plug to the rear of the
PTO cover (Fig. 1). Dry fill is approximately 4.5 liters
(9.5 pints) or to the bottom edge of the fill plug hole.
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.
The shift pattern is in a modified H pattern (Fig.
2). Overdrive fifth and sixth gears are in line and
outboard of the first through fourth gear positions.
Reverse gear is to the right of fifth and sixth and for-
ward of the neutral gate.The gear ratios are:
GEAR RATIOS
GEAR RATIO
FIRST 5.63:1
SECOND 3.38:1
THIRD 2.04:1
FOURTH 1.39:1
FIFTH 1.00:1
SIXTH 0.73:1
REVERSE 5.63:1
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.
21 - 46 MANUAL - NV5600BR/BE

OPERATION
The driver selects a particular gear by moving the
shift lever to the desired gear position. As the shift
lever moves the selected shift rail, the shift fork
attached to that rail begins to move. The fork is posi-
tioned in a groove in the outer circumference of the
synchronizer sleeve. As the shift fork moves the syn-
chronizer 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 friction cone and eventually willslide over the teeth, locking the gear to the main-
shaft or countershaft through the synchronizer.
DIAGNOSIS AND TESTING
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. 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 recommendations 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.
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 housing will be from the hous-
ing oil seals. Leaks at component mating surfaces
will probably be the result of inadequate sealer, gaps
in the sealer, incorrect bolt tightening or use of a
non-recommended sealer. A leak at the front of the
transmission will be from either the front bearing
retainer or retainer seal. Lubricant may be seen drip-
ping from the clutch housing after extended opera-
tion. If the leak is severe, it may also contaminate
the clutch disc causing the disc to slip, grab and or
chatter.
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.

CAM/OVERDRIVE PISTON
RETAINER
DESCRIPTION
The overrunning clutch (Fig. 178) consists of an
inner race, an outer race (or cam), rollers and
springs, and the spring retainer. The number of roll-
ers and springs depends on what transmission and
which overrunning clutch is being dealt with.
OPERATION
As the inner race is rotated in a clockwise direction
(as viewed from the front of the transmission), the
race causes the rollers to roll toward the springs,
causing them to compress against their retainer. The
compression of the springs increases the clearance
between the rollers and cam. This increased clear-
ance between the rollers and cam results in a free-
wheeling condition. When the inner race attempts to
rotate counterclockwise, the action causes the rollers
to roll in the same direction as the race, aided by the
pushing of the springs. As the rollers try to move in
the same direction as the inner race, they are
wedged between the inner and outer races due to the
design of the cam. In this condition, the clutch is
locked and acts as one unit.

DIAGNOSIS AND TESTING
WHEEL INSPECTION
Inspect wheels for:
²Excessive run out
²Dents or cracks
²Damaged wheel lug nut holes
²Air Leaks from any area or surface of the rim
NOTE: Do not attempt to repair a wheel by hammer-
ing, heating or welding.
If a wheel is damaged an original equipment
replacement wheel should be used. When obtaining
replacement wheels, they should be equivalent in
load carrying capacity. The diameter, width, offset,
pilot hole and bolt circle of the wheel should be the
same as the original wheel.
WARNING: FAILURE TO USE EQUIVALENT REPLACE-
MENT WHEELS MAY ADVERSELY AFFECT THE
SAFETY AND HANDLING OF THE VEHICLE. USED
WHEELS ARE NOT RECOMMENDED. THE SERVICE
HISTORY OF THE WHEEL MAY HAVE INCLUDED
SEVERE TREATMENT OR VERY HIGH MILEAGE. THE
RIM COULD FAIL WITHOUT WARNING.
STANDARD PROCEDURE - DUAL REAR WHEEL
INSTALLATION
Dual rear wheels use a special heavy duty lug nut
wrench. It is recommended to remove and install dual
rear wheels only when the proper wrench is available.
The wrench is also use to remove wheel center caps for
more information refer to Owner's Manual.
The tires on both wheels must be completely raised
off the ground when tightening the lug nuts. This
will ensure correct wheel centering and maximum
wheel clamping.
A two piece flat face lug nut with right-hand
threads is used for retaining the wheels on the hubs
(Fig. 20).The dual rear wheel lug nuts should be tightened
according to the following procedure:
²Place two drops of oil to the interface of the nut/
washer (Fig. 20) before installing on the wheel stud.
NOTE: Do not use more then two drops of oil on
the nut/washer, since the center caps attach in this
area.
²Tighten the wheel lug nuts in the numbered
sequential pattern until they are snug tight. Then
tighten lug nut to specified torque following same
number sequence, (Refer to 22 - TIRES/WHEELS/
WHEELS - SPECIFICATIONS).
²Tighten lug nuts in same numbered sequence a
second time to the specified torque. This will ensure
that the wheels are thoroughly mated.
²Check lug nut specified torque after 100 miles
(160 kilometers). Also after 500 miles (800 kilome-
ters) of vehicle operation.
NOTE: Wheel lug nuts should be tightened to spec-
ified torque at every maintenance interval thereafter.
