Thermal Switch Operation l2WD)
During 4WD operation, pressure-regulated fluid is in contact with the clutch piston and the thermal switch.
lf the temperature of the fluid in the differential goes too high, the thermal switch pushes open the relief valve R. This
causes the pressure in the clutch piston to drop, and 4WD mode is disengaged.
THERMAL SWITCHRELIEF VALVE
Reliet Valve Operation
When the fluid pressure goes higher than the relief valve spring force, check valve R opens. Pressure applied at the clutch
piston is held constant. This feature adds stability by preventing the rear wheel drive system from experiencing excessive
to rque.

Inspection
Flow Control Valve
1. Check the flow control valve for wear, burrs, and
other damage to the edges of the grooves in thevalve.
'97 model:
FLOWCONTROL VALVE
Check fordamage to edges.
'98 - 0O mod€ls:
FLOW CONTBOL VALVE
Check for damageto edges.
Insp€d the bore of the flow control valve tor scratchesor wear.
Slip the valve back in the pump, and check that itmoves in and out smoothly. lf OK, go to step 4; ifnot, replace the pump as an assembly. The flowcontrolvalve is not available separately.
CONTROL VALVE
4. Attach a hose to the end of the valve as shown.
FLOW CONTROL VALVE HOSE

5. Submerge the valve in a container of power steer-
ing fluid or solvent, and blow in the hose. lf air bub-
bles leak through the valve at less than 98 kPa
(1.0 kgflcm', 14.2 psi), repair it as follows ('97 model).
For'98 - 00 models, the flow control valve cannot
be disassembled; replace the pump as an assembly

6.For'97 model only, hold the bottom end of the
valve with a open end wrench. Unscrew the seat in

Clean all the parts in solvent, dry them otf, then
reassemble and retest the valve.
The relief pressure is adjusted at the factory by
adding shims under the check ball seat lf you found
shims in your valve, be sure you reinstall as many
as you took out.
lf the flow control valve tests OK, reinstall it in the
pump. It the flow control valve still leaks air, replace
the pump as an assembly. The flow control valve is
not available separately.

Ball Bearing:
'1. Inspect the ball bearing by rotating the outer race
slowly. lf any play or roughness is felt, replace the
ball bearing.
2. Replace the ball bearing using a press.
