INSPECTION AFTER DISASSEMBLY
Shift Rod Components

●

Check the working face of the shift rod and fork for wear, partial
wear, bending and other abnormality. If any is found, replace
with a new one.

●

Measure the clearance between the shift fork and sleeve. If it is
out of specification, replace it with a new one.

Planetary Carrier

●

Measure the end play of each pinion gear. If it is out of specifica-
tion, replace the planetary carrier assembly with a new one.

●

Check the working face of each gear and bearing for damage,
burrs, partial wear, dents and other abnormality. If any is found,
replace the planetary carrier assembly with a new one.

Sun Gear

●

Check if the oil passage of the sun gear assembly is clogged.
For this, try to pass a 3.6 mm (0.142 in) dia. pin through the oil
passage as shown.

●

Check the sliding and contact surface of each gear and bearing
for damage, burrs, partial wear, dents, and other abnormality. If
any is found, replace the sun gear assembly with a new one.

Internal Gear

●

Check the internal gear teeth for damage, partial wear, dents
and other abnormality. If any is found, replace the internal gear
with a new one.

Gears and Drive Chain

●

Check the gear faces and shaft for wear, cracks, damage, and
seizure.

●

Check the surfaces which contact the sun gear, clutch drum,
clutch hub, press flange, clutch piston and each bearing for
damage, peel, partial wear, dents, bending, or other abnormal
damage. If any is found, replace with a new one.

Pinion gear end play

Bearing

●

Make sure the bearings roll freely and are free from noise, pit-
ting and cracks.

Main Oil Pump

Check the inner and outer circumference, tooth face, and side-
face of the inner and outer gears for damage or abnormal wear.

Measure the side clearance between the main oil pump housing
edge and the inner and outer gears.

Make sure the side clearance is within specification. If the mea-
surement is out of specification, replace the inner and outer
gears with new ones as a set. Refer to

TF-183, "Main Oil Pump"

Sub-oil Pump

Check the inner and outer circumference, tooth face, and side-
face of the inner and outer gears for damage or abnormal wear.

Measure the side clearance between the sub oil pump housing
edge and the inner and outer gears.

Make sure the side clearance is within specification. If the mea-
surement is out of specification, replace the inner and outer
gears with new ones as a set. Refer to

TF-183, "Sub-oil Pump"

Control Valve

●

Check resistance between the terminals of the clutch pressure
solenoid valve, 2-4WD shift solenoid valve, clutch pressure
switch, line pressure switch and the transfer fluid temperature
sensor. Refer to

TF-91, "Clutch Pressure Solenoid"

(clutch

pressure solenoid valve),

TF-95, "COMPONENT INSPECTION"

(2-4WD solenoid valve),

TF-108, "COMPONENT INSPECTION"

(clutch pressure switch),

TF-111, "COMPONENT INSPECTION"

(line pressure switch) and

TF-105, "COMPONENT INSPEC-

TION"

(transfer fluid temperature sensor).

●

Check the sliding faces of the control valves and plugs for
abnormality. If any is found, replace the control valve assembly
with a new one. Refer to

TF-184, "Control Valve"

CAUTION:

Replace control valve body together with clutch return
spring as a set.

●

Check each control valve spring for damage or distortion. Also
check its free length, outer diameter and wire diameter. If any
damage or fatigue is found, replace the control valve body with a
new one. Refer to

TF-184, "Control Valve Spring"

CAUTION:

Replace control valve body together with clutch return
spring as a set.

Clutch

●

Check the drive plate facings and driven plate for damage,
cracks or other abnormality. If any abnormalities are found,
replace with a new one.

●

Check the thickness of the drive plate facings and driven plate.
Refer to

TF-183, "CLUTCH"

CAUTION:

●

Measure facing thickness at 3 points to take an average.

●

Check all drive and driven plates.

●

Check return spring for damage or deformation.

●

Do not remove spring from plate.

Return Spring

●

Check the stamped mark shown. Then, check that the free
lengths, (include thickness of plate) are within specifications. If
any abnormality is found, replace with a new return spring
assembly of the same stamped number. Refer to

Align the dowel pin hole and bolt hole of the sub oil pump
assembly with the center case. Install the sub oil pump cover.
Then tighten to the specified torque. Refer to

TF-146, "COMPO-

NENTS"

Apply ATF to the new O-ring and install it to the transfer motor.

CAUTION:

Do not reuse O-rings.

Fit the double-flat end of the transfer motor shaft into the slot of
the sub-oil pump assembly. Then tighten to the specified torque.
Refer to

TF-146, "COMPONENTS"

CAUTION:

Be sure to install connector bracket.

Assemble the control valve assembly with the following procedure.

CAUTION:

●

Do not reuse any part that has been dropped or damaged.

●

Make sure valve is assembled in the proper direction.

●

Do not use a magnet because residual magnetism stays during assembly.

Clean the upper body (5), control valves (3) and springs (4) with
cleaning agent, and dry with compressed air.

Dip the control valves in ATF, and apply ATF to the valve-mount-
ing area of the upper body.

Install each control valve, spring, and plug to the upper body,
and install retainer plates to hold them in place.

CAUTION:

●

To insert control valves into upper body, place upper
body on a level surface in order to prevent flaw or dam-
age.

●

Make sure each control valve is smoothly inserted.
