1. Warm up engine.
2. Turn ignition switch OFF.
3. Using CONSULT-II, make sure no error codes are indicated for
self-diagnosis items. Refer to EC-39, “CONSULT-II Inspection
Procedure”.
Do not disconnect CONSULT-II until the end of this operation;
it will be used to check engine rpm and for error detection at
the end of this operation.
4. Disconnect the negative battery terminal.
5. To prevent fuel from being injected during inspection, remove
fuel injection pump fuse [ENG CONT2 (20A)] from fuse box on
the left side of engine compartment.
6. Remove glow plugs from all the cylinders.
Before removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
Carefully remove glow plugs to prevent any damage or
breakage.
Handle with care to avoid applying any shock to glow
plugs.
SEM112G
7. Install adapter (SST) to installation holes of glow plugs and
connect compression gauge for diesel engine.
: 18 - 21 N·m (1.8 - 2.2 kg-m, 13 - 15 ft-lb)
8. Connect battery negative terminal.
9. Set the ignition switch to “START” and crank. When gauge
pointer stabilizes, read compression pressure and engine rpm.
Repeat the above steps for each cylinder.
Always use a fully-charged battery to obtain specified
engine speed.

When engine rpm is out of the specified range, check the spe-
cific gravity of battery liquid. Measure again under corrected
conditions.
If engine rpm exceeds the limit, check valve clearance and
combustion chamber components (valves, valve seats, cylin-
der head gaskets, piston rings, pistons, cylinder bores, cylin-
der block upper and lower surfaces) and measure again.
10. Complete this operation as follows:
a. Turn the ignition switch to “OFF”.
b. Disconnect battery negative terminal.
c. Install glow plugs.

For the locations and arrangement of intake and exhaust
valves, refer to the figure.

5. Remove valve oil seals.
Use a valve oil seal puller (SST) for removal.
6. Remove valve spring seats.
7. When removing valve seats, check valve seat contact. Refer
to EM-52.
8. Before removing valve guides, check valve guide clearance.
Refer to EM-50, “VALVE GUIDE CLEARANCE”.
9. Remove glow plugs.
To avoid damage, glow plugs should be removed only
when required.
Handle with care to avoid applying shock. (When dropped
from approx. 100 mm (3.94 in) or higher, always replace
with a new one.)

InspectionNJEM0065CYLINDER HEAD DISTORTIONNJEM0065S01Clean surface of cylinder head.
Use a reliable straightedge and feeler gauge to check the flatness
of cylinder head surface.
Check along six positions shown in the figure.
Head surface flatness: Limit 0.04 mm (0.0016 in)
If beyond the specified limit, resurface or replace it.
The limit for cylinder head resurfacing is determined by the
cylinder block resurfacing.
Resurfacing limit:
Amount of cylinder head resurfacing is “A”.
Amount of cylinder block resurfacing is “B”.
The maximum limit: A + B = 0.07 mm (0.0028 in)
After resurfacing cylinder head, check that camshaft rotates freely
by hand. If resistance is felt, cylinder head must be replaced.
Nominal cylinder head height:
153.9 - 154.1 mm (6.059 - 6.067 in)

VALVE SEATSNJEM0065S10Before starting this check, confirm that the dimensions of valve
guides and valves are as specified.
Apply red lead primer on contacting surfaces of valve 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.

REPLACING VALVE SEAT FOR SERVICE PARTSNJEM0065S111. 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.
2. Ream cylinder head recess for service valve seat.
Oversize [0.5 mm (0.020 in)]:
Intake 30.500 - 30.516 mm (1.2008 - 1.2014 in)
Exhaust 29.500 - 29.516 mm (1.1614 - 1.1620 in)
Be sure to ream in circles concentric to the valve guide
center.
This will enable valve seat to fit correctly.

3. Heat cylinder head to 110 to 120°C (230 to 248°F) by soaking
in heated oil.
4. Sufficiently cool valve seat with dry ice. Force fit valve seat into
cylinder head.
WARNING:
Do not touch cold valve seat with your bare hands.
5. Cut or grind valve seat using suitable tool to the specified
dimensions as shown in SDS (EM-90).
CAUTION:
Use the valve seat cutter properly. Securely gripping the cut-
ter handle with both hands, press the cutter down onto the
entire circumference of the contacting surface and finish cut-
ting at one time. Improper pressing of the cutter or cutting in
several steps may result in staged surface on the valve seat.
6. After cutting, lap valve seat with abrasive compound.
7. Check valve seating condition. Refer to EM-52, “Valve Seats”.
JEM253G
8. Use a depth gauge to measure the distance between the
mounting surface of the cylinder head spring seat and the
valve stem end. If the distance is shorter than specified, repeat
step 5 above to adjust it. If it is longer, replace the valve seat
with a new one.
Valve seat resurface limit “L”:
Intake 36.53 - 36.98 mm (1.4382 - 1.4559 in)
Exhaust 36.53 - 37.01 mm (1.4382 - 1.4571 in)
