TRANSFER ASSEMBLY

Control Valve Assembly

1. Disassemble 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 disassembly.

a. Remove all the bolts except for the two shown.

b. Remove the following from the control valve assembly:

• Clutch pressure solenoid valve

• Clutch pressure switch

• 2-4WD shift solenoid valve

• Line pressure switch

• Transfer fluid temperature sensor

Remove the O-rings from each solenoid valve, switch and termi-

nal body.

d. Place the control valve with the lower body facing up. Remove

the two bolts, and then remove the lower body and separator

plate from the upper body.

CAUTION:

Do not drop relief balls. Detach lower body carefully.

e. Make sure the reverse balls, relief balls, relief springs, accumu-

lator pistons and valve springs are securely installed as shown,

and remove them.

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.

TRANSFER ASSEMBLY

• 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 pas-

sage 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 sei-

zure.

• 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.

• Make sure the bearings roll freely and are free from noise, pitting

and cracks.

Main Oil Pump

1. Check the inner and outer circumference, tooth face, and side-

face of the inner and outer gears for damage or abnormal wear.

2. Measure the side clearance between the main oil pump housing

edge and the inner and outer gears.

3. 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

DLN-191, "Inspection

and Adjustment"

Sub-oil Pump

1. Check the inner and outer circumference, tooth face, and side-

face of the inner and outer gears for damage or abnormal wear.

2. Measure the side clearance between the sub oil pump housing

edge and the inner and outer gears.

3. 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

DLN-191, "Inspection

and Adjustment"

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

DLN-63, "Component Inspection"

(clutch pressure sole-

noid valve),

DLN-67, "Component Inspection"

(2-4WD solenoid

valve),

DLN-79, "Component Inspection"

(clutch pressure switch),

TRANSFER ASSEMBLY

• Check the sliding faces of the control valves and plugs for abnor-

mality. If any is found, replace the control valve assembly with a

new one. Refer to

DLN-191, "Inspection and Adjustment"

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 dam-

age or fatigue is found, replace the control valve body with a new

one. Refer to

DLN-191, "Inspection and Adjustment"

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

DLN-191, "Inspection and Adjustment"

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 abnor-

mality is found, replace with a new return spring assembly of the

same stamped number. Refer to

DLN-191, "Inspection and Adjust-

ment"

ASSEMBLY

Control Valve Assembly

1. 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.

• 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.

d. Install the reverse balls, relief balls and relief springs, accumula-

tor pistons and valve springs to the upper body.

e. Install the lower body and separator plate to the upper body.
