Bearing Outer Race Replacement
Note these items:
. The bearing outer race and tapered roller bearingshould be replaced as a set.. lnspect and adjust the tapered roller bearing preload
whenever the tapered roller bearing is replaced.
'1. Remove the oil seals from the transmission housingand clutch housing (see page j3-43).
2. Drive the bearing outer race and thrust shim out ofthe transmission housing, or remove the bearingouter race and 75 mm shim from the clutch housingby heating the clutch housing to about 212"F(100"C) with a heat gun. Do not reuse the thrustshim if the outer race was driven out.

1. Remove the bearing outer race and thrust shim
from the transmission housing (see page 13-40)'
NOTE:
. Do not reuse the thrust shim if the bearing outer
race was driven out.
. Let the transmission cool to room temperature il
the bearing outer race was removed by heating
the clutch housing.
2. Do not use more than one thrust shim to adjust the
tapered bearing preload. First try the same size
thrust shim that was removed. There are no shims
used on the clutch housing side
SHIMTHRUST
/A
After installing the thrust shim, install the bearing
outer race in the transmission housing (see page
13-40).
With the mainshaft and countershaft removed,
install the differential assembly, and torque the
clutch housing and transmission housing.
NOTE: lt is not necessary to use sealing agent be-
tween the housings.

Pump Pressure Check With T/N 07406 -
Check the fluid pressure as follows to determine whether
the trouble is in the pump or gearbox.
1. Check the power steering tluid level (see page 17-
151, and pump belt tension (see page 17-14).
2. Disconnect the pump outlet hose from the pump
outlet with care so as not to spill the power steering
fluid on the frame and other parts, then install the
P/S joint adapter (pump) on the pump outlet.

Start the engine and let it idle.
Turn the steering wheel from lock-to-lock several
times to warm the tluid to operating temperature.
Measure steady-state fluid pressure while the engine
is idling. It the pump is in good condition, the gauge
should read 1,500 kPa (15 koflcm',213 psi). lf it reads
high. check the outlet hose or valve body unit {see
General Troubleshooting),
Close the-pressure control valve gradually and read
the oressure.
CAUTION: Do not keep the pressurs control valve
closed more then 5 seconds or the pump could bo
damaged by overheating.
lmmediately open the pressure controlvalve fully.
lf the pump is in good condition, the gauge should
read at least 6,900 - 7;800 kPa (70 - 80 kgflcm',
1,000 - 1.140 psi), A low reading means pump out-
Dut is too low for {ull assist. Repair or replace the

Moldings
Door Moldings Replacement (cont'd)
It the old molding is to be reinstalled:
The following materials and tools are required to repair
the molding.
NOTE: Followthe manufacturer's instructions.
Materials: (Reference)
. Stripe remover
3M 08907
. Stripe adhesive remover
3M 08908
. Adhesive tape
3M Super Automotive Attachment Tape
Tools:
. Protective tape
. Knife or Cutter
. Sponge or Shop towel
. Infrared dryer
. Film
. Plastic putty knife
. Alcohol
CAUTION: Put on gloves to protect your hands,
1. lf necessary, replace any damaged clips on the mold-
ang.
2. Apply the stripe remover evenly to the bonding sur-
face of the body and molding.
3. Cover the bonding surface of the body and molding
with a film, then heat to 104 - 122"F (40 - 50'C) for 5- 10 minutes with an infrared dryer.
NOTE: Use care when heating to prevent deforma-
tion of the body and molding.
4. Carefully scrape the adhesive tape with a plastic
putty knife.
For removal of adhesive tape residue, follow-up with
stripe adhesive remover, then scrape the adhesive
tape with a plastic putty knife.
Remove the protective tape, then clean the bonding
surface with a sponge dampened in alcohol.
NOTE: Make sure the bonding surface is kept free or
water, oil and grease.
