AND
INSTALLATION

• • Use a D.C. welder set at straight polarity, or use
an A.C. welder if the proper electrode is available
• Use 1/8 inch diameter welding rod and a welding
current of 80 to 125 amps. • Direct arc at intersection of gear and front cover at
an angle of 45° from rear face of gear.

(6)
Weld new ring gear to torque converter front
cover. Take care to place same amount of weld mate­
rial (or as nearly as possible) in original weld loca­

tions.
This is essential in maintaining converter
balance. Position welds alternately on opposite sides of converter and ring gear to minimize distortion.
(7) Inspect gear teeth and remove any nicks, raised
metal, weld spatter, or rough surfaces.

AND TORQUE CONVERTER INSTALLATION—2-WHEEL DRIVE

(1) Mount transmission on jack. Secure transmis­
sion with safety chains. (2) Check converter hub and hub drive notches for
sharp edges, burrs, scratches, or nicks. Polish hub
and notches with 400 grit wet/dry paper or crocus
cloth if necessary. Hub surface must be smooth to avoid damaging pump seal at installation. (3) Lubricate converter drive hub and pump seal
lip with transmission fluid. (4) Install converter in oil pump.
(5) Verify that converter is fully seated. Use
straight edge and steel ruler to check seating (Fig.
10).
Surface of converter lugs should be approxi­
mately 13 mm (1/2 in.) to rear of straight edge when
converter is fully seated. (6) Temporarily secure converter with C-clamp at­
tached to housing or with metal strap attached across converter housing. (7) Mount transmission on jack and secure it with
safety chains. (8) Check condition of converter driveplate. Re­
place plate if cracked, distorted or damaged. If driveplate replacement was necessary, be sure
transmission dowel pins are seated in engine
block and protrude far enough to held transmis­ sion in alignment. (9) Raise transmission and align converter with
crankshaft and drive plate.

GENERAL
INFORMATION

The NP205 transfer case
is a
heavy duty, part-time
unit with constant mesh, helical gears.
The
gears
are

mounted
in a
one-piece, cast iron gear case. The NP205 provides four operating ranges which

are:
4-wheel drive high, neutral, 2-wheel drive high
and 4-wheel drive
low (Fig. 1).
The transfer case gears rotate
on
shafts supported
by ball
and
roller bearings. Sliding clutch sleeves and shift forks
are
used
to
engage
or
disengage
the

drive gears. The NP205 geartrain provides high
and low
ranges
in 4-wheel drive mode.
The
high range
has a 1:1 ra­

tio
for
normal operation
and a low
range with
a re­
duction ratio
of 1.96:1 for
extra pulling power
in off

road situations. In two-wheel drive range,
the
transfer case front
output shaft drive gear
is
disengaged. Torque
is not

transmitted
to the
front propeller shaft.

SAE multi-purpose gear lubricants with
an API

grade rating
of GL 5 are
recommended
for
severe
duty operation.
SAE
grades
80,
75W-90,
90,
80W-90, 140
and
80W-140
are all
acceptable.
Use
SAE 80 or
75W-90 when ambient tempera­
tures
are
below
-23° C (-10° F). Use SAE 90, or
80W-90 when ambient temperature
is
above
the

stated range.
SAE
140, or
80W-140
can be
used when severe ser­
vice
is
anticipated,
or
when ambient temperatures are expected
to
exceed +32°
C (90° F).

Transfer Case Shift Linkage Lubrication
The transfer case shift linkage pivot
and
contact
surfaces should
be
lubricated with engine
oil at
rec­
ommended intervals. Lubrication frequency
for the

linkage
is
described
in
Lubrication
And
Maintenance Group
O.

TRANSFER CASE
IDENTIFICATION
The NP205 identification
tag is
attached
to the

PTO cover
on the
driver side
of the
transfer case.
The
tag
contains transfer case manufacturing
and as­
sembly part numbers. Refer
to
this information when
ordering service replacement parts.

SERVICE
DIAGNOSIS
The most frequent causes
of
transfer case malfunc­
tions
are:
• improper operation
• insufficient lubricant
• non-recommended lubricant
• misadjusted shift linkage
• improper assembly after repair. The general problems
and
causes
of
transfer case
malfunctions
are
outlined below.

LOW LUBRICANT LEVEL
A
low
lubricant level
is
usually
the
result
of
loose
components, leakage,
or
improper checking and/or
filling techniques. Lubricant leaks
can
occur
at the
shaft seals, case
vent,
or
gasket joints. Most leaks will
be
evident
by

the presence
of
lubricant around
the
leakage point. However,
be
sure
the
leakage
is
actually from
a

transfer case component.

HEATING
AND AIR
CONDITIONING

• housing is expelled through the molded rubber drain
tube into the engine compartment. The tube must be
kept open to prevent condensation from collecting in
the bottom of the housing.
The squeezed rubber flap at the drain tube tip is
designed to keep engine compartment air from enter­ ing into the system yet allow condensation to drain.
If the tip is not properly formed or has been dam­
aged, the system will not drain properly. Therefore,
if the tube is damaged, it should be replaced.
• SERVICE VALVES—The service valves at the
compressor suction line and discharge tube are used
to test and service the refrigerant system. A special adapter (Tool C-4803) is required for performance
testing.
OPERATION The compressor increases the pressure and temper­
ature of the refrigerant. The heated refrigerant vapor
is then pumped into the condenser where it cools by
giving off heat to air passing over the condenser fins.
As the refrigerant cools in the condenser, it con­
denses into a liquid. Still under high pressure, the
liquid refrigerant passes into the receiver. The re­
ceiver acts as a reservoir to furnish refrigerant to the
expansion (H) valve at all times. From the receiver,
the high pressure liquid refrigerant passes to the ex­ pansion (H) valve. The expansion (H) valve meters
refrigerant into the evaporator where a low pressure
is maintained by the suction side of the compressor.
As it enters the evaporator, the refrigerant immedi­ ately begins to boil by absorbing heat from the air
passing over the evaporator core. Having given up its
heat to boil the refrigerant, the air is cooled and
passes into the passenger compartment of the vehi­
cle.
From the evaporator the vaporized refrigerant is
drawn back to the compressor to repeat the cycle. RADIATOR CAP
Air conditioned vehicles must be equipped with a
radiator cap having a holding pressure of 98-122 kPag (14-18 psig). Replace the radiator cap that does
not test within this specification.
CONDENSER Inspect the condenser for obstruction or foreign
matter. Clean if present.
Any obstruction to the free flow of air across the
condenser will decrease heat dissipation from the
condenser. This will in turn decrease the efficiency of
the condenser and decrease the evaporator's effi­
ciency. These conditions result in increasing the dis­
charge pressure and horsepower load on the engine.
The use of a bug screen is not recommended, it also
will decrease the free flow of air.
Inspect the condenser for bent or damaged fins.
The bent fins on the condenser deflect air flow and
decrease the condenser area.
BUG SCREENS Bug screens should NOT be installed on vehicles
equipped with air conditioning. A bug screen in­
stalled in front of the condenser will reduce air flow
and air conditioner performance. Under severe heat
conditions a bug screen may cause the engine to
over-heat.
RESISTOR
BLOCK
The blower motor switch and resistor block, con­
trols the speed of the blower motor. The resistor
block consists of 3 helical-wound wire resistors, con­ nected to terminals which are mechanically attached
to a phenolic board. This assembly is bolted to the
plenum.
The blower switch controls the blower motor speed
by selectively connecting in series one, two, three or none of the resistors to the blower motor.

HEATING AND AIR CONDITIONING 24 - 7 AIR CONDITIONING SYSTEM
SIGHT GLASS REFRIGERANT LEWEL TEST The sight glass, which is an integral part of the fil­
ter-drier, is a refrigerant level indicator (Fig. 2). To check the refrigerant level, clean the sight glass and
start the engine. Place the air conditioning controls
on A/C, the fan switch on high and the temperature lever on cool. The room temperature should be at
least 21°C (70°F). After operating for a few minutes
in this manner, check the sight glass.

Fig.
2 Sight Glass
(1) If the sight glass is clear, the A/C clutch is en­
gaged, the compressor discharge line is warm and
the compressor inlet line is cool; the system has a
full charge.
(2) If the sight glass is clear, the A/C clutch is en­
gaged and there is not significant temperature differ­
ence between compressor inlet and discharge lines;
the system is empty or nearly empty. Connect a gauge to the compressor discharge port. If the gauge
reads less than 172 kPag (25 psi), the suction tube cycling switch has failed.
(3) If the sight glass is clear and the A/C clutch is
disengaged; the clutch is defective or, the clutch circuit
is open, or the system is out of refrigerant. Perform suc­
tion tube cycling switch test to determine condition.
(4) If the sight glass shows foam or bubbles, the
system could be low on charge. Occasional foam or
bubbles is normal when the room temperature is above 43°C (110°F) or below 21°C (70°F).
Adjust the engine speed to 1,300 RPM. Block the
airflow through the condenser to increase the com­
pressor discharge pressure to 1 552-1 724 kPag (225- 250 psig). If sight glass still shows bubbles or foam,
system charge level is low. The refrigerant system will not be low on charge un­
less there is a leak. Find and repair the leak. If the leak
can be repaired without discharging the system, the low
refrigerant charge level can be corrected as follows.
Maintaining the discharge pressure of 1 550-1 720 kPag (225-250 psig), add refrigerant gas through compressor
suction line until foam is cleared from sight glass. Then
add 13 oz. (368 g) or 1 can of refrigerant.
HIGH PRESSURE RELIEF
WALWE
The high pressure relief valve vents only a small
amount of refrigerant necessary to reduce system pres­
sure and then reseats
itself.
The majority of the refrig­
erant is conserved in the system. The valve is calibrated
to vent at a pressure of 3 100-3 790 kPag (450-550

psig).
However, the fact that the valve vented refriger­ ant, does not mean the valve is defective.
ELECTRONIC TEMPERATURE CYCLING
SWITCH TEST The electronic temperature cycling switch (Fig. 3) is
located on the refrigerant plumbing, suction line near
the H-valve. It electrically inputs to the engine control­ ler on gasoline vehicles and in series with the clutch
coil on diesel vehicles. The switch turns the compressor
on and off depending on the temperature in the suction

line.
The switch is a sealed, specially calibrated unit and if found defective, must be replaced.
