FRONT AXLE PARTSNJAX0005Check front axle and front suspension parts for excessive play,
cracks, wear or other damage.
+Shake each front wheel to check for excessive play.
+Make sure that cotter pin is inserted.
+Retighten all axle and suspension nuts and bolts to the speci-
fied torque.
Tightening torque:
Refer to SU-9, ªFRONT SUSPENSIONº.

FRONT WHEEL BEARINGNJAX0006+Check that wheel bearings operate smoothly.
+Check axial end play.
Axial end play:

RemovalNJBR0123
SBR631E
1. Remove parts shown below.
+Air duct, air cleaner case (upper)
+Engine cover
+Rocker cover
+Exhaust manifold cover
+EGR tube
2. Disconnect vacuum hose from vacuum pump.
3. Remove cylinder head rear cover plate.
+Use a tool such as seal cutter (SST) to remove.
4. Loosen and remove rear cam sprocket installation bolts.
+Camshaft should not be attached. Using engine inner
resistance, loosen installation bolts.
SBR632E
5. Remove vacuum pump and cylinder head rear cover assem-
bly.
+Remove and install vacuum pump, sprocket, drive chain, and
chain guide as an assembly.
+Loosen mounting bolts in the reverse order of the numbers
shown in the figure to the left.
+Remove only bolts that are shown in the figure. (Be especially
careful not to remove M6 bolts on the vacuum pump.)
+Use a tool such as a seal cutter (SST).

InstallationNJBR01241. Assemble vacuum pump and cylinder head rear cover
assembly, referring to ªComponentº in the next page.
2. Install vacuum pump and cylinder head rear cover assembly to
cylinder head.
a. Apply ThreeBond 1207C (KP510 00150) without breaks to the
location shown in the figure to the left.
SBR632E
b. Tighten the mounting bolts in the numerical order shown by the
figure to the left.
3. Install rear cam sprocket installation bolts.
4. Remove sprocket retaining two M6 bolts.
+M6 bolts will be used for installation.
5. Tighten rear cam sprocket installation bolts.
+Camshaft should not be fixed. Using engine inner resistance,
tighten installation bolts.
SBR634E
6. Install cylinder head rear cover plate.
+Apply ThreeBond 1207C (KP510 00150) without breaks to the
location shown by the figure to the left.
7. Install parts in the reverse order of removal.
CAUTION:
If the engine is started with vacuum pump released (vacuum
hose disconnected), it causes increase of blowby gas amount,
and engine damage may result. When starting the engine, be
sure to close vacuum circuit.
SBR611E
InspectionNJBR0125+Remove vacuum hose. Then, connect vacuum gauge with
three-way connector.
+Install three-way connector to the area where vacuum pump
negative pressure can be directly measured. (The figure
shown an example.)
+Start the engine, then measure negative pressure.
Standard: þ86.6 to þ101.3 kPa (þ866 to þ1,013 mbar,
þ650 to þ760 mmHg, þ25.59 to þ29.92 inHg)
+If it is not within standard, inspect for suction of air in the middle
of route and measure it again.
+If it is still not within standard value, replace the vacuum pump.
