INSPECTION AFTER REMOVAL
Timing Chain
Check for cracks and excessive wear at roller links. Replace
chain if necessary.
INSTALLATION
1. Install rear chain case.
a. Apply a continuous bead of Genuine Liquid Gasket or equivalent
on locations shown in the figure. Refer to E M - 111 , "
Precautions
For Liquid Gasket" .

B, C: Minimize overlapping area of bead, by starting and ending
at areas of bead as shown in the figure. Apply so that the portion
marked * comes at an external location but cannot be viewed
externally after engine assembly.

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Using CONSULT-II, make sure no error codes are indicated for self-diagnosis items. Refer to EC-1412,
"Basic Inspection" .
●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.
3. Disconnect the negative battery terminal.
4. Remove charge air cooler. Refer to EM-122, "
Removal and Installation"
5. To prevent fuel from being injected during inspection, remove
fuel supply pump fuse [ENG CONT (20A)] from fuse box on the
left side of engine compartment.
●Among marks on fuse box, [ENG CONT 2 (20A)] is for fuel
supply pump fuse.
6. Remove glow plugs from all the cylinders. Refer to EM-138,
"Removal and Installation" .
CAUTION:
●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.
7. Install adapter to installation holes of glow plugs and connect
compression gauge for diesel engine.
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.
Compression pressure
Unit: kPa (bar, kg/cm2 , psi)/rpm
●When engine rpm is out of the specified range, check the specific 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, cylinder head gaskets, piston rings, pistons, cylinder bores, cylinder block upper and lower
surfaces) and measure again.
●If compression pressure is low in some cylinders, apply engine oil from glow plug installation hole. Then
check pressure again.
–If compression pressure becomes normal after applying engine oil, piston ring may be worn or dam-
aged. Check piston ring for malfunction. If any, replace piston ring.
–If compression pressure is still low after applying engine oil, valve may be malfunctioning. Check valve
for malfunction. If contact malfunction is found, replace valve or valve seat.
●If compression pressure in adjacent two cylinders is low after applying engine oil, pressure may be
leaking from gasket. In this case, replace cylinder head gasket.
10. Complete this operation as follows:

tion but cannot be viewed externally after engine is assembled.
3. Install cylinder head assembly.
●Tighten bolts in numerical order as shown in the figure
according to the following procedure:
a. Apply engine oil to bolt threads and seat surfaces.
b. Tighten bolts to 29 to 38 N·m (2.9 to 3.9 kg-m, 21 to 28 ft-lb).
c. Tighten 180° to 185° [target: 180°] (angular tightening).
d. Loosen completely to 0 N·m (0 kg-m, 0 in-lb) in the reverse order
of that shown in the figure.

g. Tighten another 90° to 95° [target: 90°] (angular tightening).
●When an angle wrench is not used, paint an alignment
mark on the head of cylinder head bolt and cylinder head
surface before tightening. Check the angle with a protrac-
tor.
4. Install glow plug.
●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.
●Before installing, remove carbon depositing on mounting hole of glow plug with a reamer.
