Valve Dimension

Check dimensions of each valve. For dimensions, refer to SDS,

EM-

224, "VALVE"

.

When valve head has been worn down to 1 mm (0.039 in) in margin
thickness, replace valve.
Grinding allowance for valve stem tip is 0.2 mm (0.008 in) or
less.

Valve Guide Clearance

Perform the inspection before removing valve guides.

Check that the valve stem diameter is within specifications.

Push valve approximately 25 mm (0.98 in) toward combustion
chamber, move valve toward dial indicator to measure valve
movement.

Valve guide clearance is 1/2 of movement on dial indicator.

If the measured value exceeds the limit, replace valve guide.

Valve Guide Replacement

When removing valve guide, replace it with oversized [0.2 mm
(0.0008 in)] valve guide.

1.

Heat cylinder head to 110 to 130

°

C (230 to 266

°

F) in oil bath.

2.

Using valve guide drift, tap valve guides out from the combus-
tion chamber side.

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.

Check 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 abnormal 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.

Cut valve seat to make it thin, and pull it out.

WARNING:

Situate vehicle on a flat and solid surface.

Place chocks at front and back of rear wheels.

For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.

CAUTION:

Always be careful to work safely, avoid forceful or uninstructed operations.

Do not start working until exhaust system and coolant are cool enough.

If items or work required are not covered by the engine main body section, refer to the applicable
sections.

Always use the support point specified for lifting.

Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.

For supporting points for lifting and jacking point at rear axle, refer to GI-43, “Lifting Points and
Tow Truck Towing”.

ing pace of the hoist, and remove engine and transaxle assem-
bly from vehicle.

CAUTION:

While working, check that no parts of engine assembly
interfere with adjacent parts on the vehicle.

to components illustration.

Make sure that each mounting insulator is seated properly, and tighten mounting bolts and nuts.

INSPECTION AFTER INSTALLATION

Before starting engine check the levels of coolant, lubrications and working oils. If less than required
quantity, fill to the specified level.

Before starting engine, bleed air from fuel piping. Refer to FE-18, “Bleeding Fuel Filter”.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of coolant, lubricants, working oil, fuel and
exhaust gas.
