4. Heat cylinder head to 110 to 130°C (230 to 266°F) in oil bath.
5. Using the valve guide drift (commercial service tool), press fit
valve guides from camshaft side, referring to the dimension
shown in the figure.
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
6. Using the valve guide reamer (commercial service tool), perform
reaming to the press-fitted valve guides.
Valve Seat Contact

Before starting this check, confirm that the dimension of valve
guide and valves are as specified.

Apply red lead primer on contacting surfaces of valves seat and
of valve face to examine the conditions of contacting surfaces.

Make sure that the paint on contacting surfaces is continuous
along the entire circumference.

If there are abnormal indications, grind the valve and check the
contact again. If malfunction indications still persist, replace
valve seat.
Valve Seat Replacement
When removing valve seat, replace it with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-240, "
Va l v e S e a t" .

PRECAUTIONS

Service NoticeEDS001V7

After overhaul refill the transfer with new transfer oil.

Check the oil level or replace the oil only with the vehicle parked on level ground.

During removal or installation, keep inside of transfer clear of dust or dirt.

Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern.
Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause
longitudinal vibration.

Disassembly should be done in a clean work area.

Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.

Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.

All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.

Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.

Gaskets, seals, O-rings and lock nuts should be replaced any time when the transfer is disassembled.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.

Observe the specified torque when assembling.

Clean and flush the parts sufficiently and blow-dry them.

Be careful not to damage sliding surfaces and mating surfaces.

Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transfer.

Trouble Diagnosis Chart for SymptomsEDS001VJ
If 4WD warning lamp turns ON, perform self-diagnosis. Refer to TF-30, "SELF-DIAG RESULT MODE" .
NOTE:

Light tight-corner braking symptom may occur depending on driving conditions in AUTO mode. This is not malfunction.

Heavy tight-corner braking symptom occurs when vehicle is driven in the following conditions: LOCK mode, steering
wheel is turned fully to either sides, and accelerator pedal was depressed.Symptom Condition Check item Reference page
