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 toEC-38,
"Basic Inspection".
lDo 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 battery cable from the negative terminal.
4. To prevent fuel from being injected during inspection, remove fuse [EGI (20A)] (1) from fuse box.
5. Remove glow plugs from all the cylinders. Refer toEM-41, "
GLOW PLUG".
CAUTION:
lBefore removal, clean the surrounding area to prevent entry of any foreign materials into
engine.
lCarefully remove glow plugs to prevent any damage or breakage.
lHandle with care to avoid applying any shock to glow plugs.
6. Install compression gauge adapter [SST] to installation holes of
glow plugs and connect compression gauge for diesel engine.
7. Connect the battery cable to the negative terminal.
8. With accelerator pedal fully depressed, turn ignition switch to
“START” for cranking. When the gauge pointer stabilizes, read
the compression pressure and engine rpm. Perform these steps
to check each cylinder.
lAlways use a fully-charged battery to obtain specified engine
speed.

Compression pressure
Unit: kPa (bar, kg/cm2, psi)/rpm
lWhen engine rpm is out of the specified range, check the specific gravity of battery liquid. Measure
again under corrected conditions.
lIf 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.
lIf 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.
lIf 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.
9. Complete this operation as follows:
a. Turn the ignition switch to “OFF”.
b. Disconnect the battery cable from the negative terminal.
c. Install glow plug and install all the parts removed in step 4.
d. Install fuse [EGI (20A)].
e. Connect the battery cable to the negative terminal.
f. Using CONSULT-II make sure no DTC is indicated for items of self-diagnosis.

lCheck the ball sliding surface for any compression scars, cracks, or fractures.
lCheck for any damage to the serrated part.
ASSEMBLY
Final Drive Side
1. Wrap the serrated part of the drive shaft with tape. Install the
boot band and boot to drive shaft.
CAUTION:
Discard the old boot band and boot: replace with new ones.
2. Remove the tape wound around the serrated part of the shaft.
3. Line up alignment marks which were made when spider assem-
bly was removed. Install spider assembly, with serration chamfer
facing drive shaft.
4. Secure spider assembly with snap ring.
CAUTION:
Discard the old snap ring: replace with new ones.
5. Apply Nissan genuine grease or equivalent to spider assembly
and sliding surface.
6. Line up matching marks on shaft and housing, and install sliding
joint housing to spider assembly. Add remaining grease up to
the amount listed below.
7. Install the stopper ring onto the housing.
CAUTION:
lDo not reuse stopper rings.
lMake sure that housing and stopper ring are fully engaged.
