Revision: 2006 January2006 M35/M45
Exhaust Manifold Gasket
Install in direction shown below. (Follow same procedure for
both banks.)
Locate thick side of port connecting part on right side from tech-
nician’s view.

order as shown in the figure.
NOTE:
Tighten nuts No. 1 and 2 in two steps. The numerical order No. 7
and 8 shows second step.
Air Fuel Ratio Sensor
CAUTION:
Before installing a new air fuel ratio sensor, clean exhaust system threads using heated oxygen
sensor thread cleaner tool (Commercial Service Tool: J-43897-18 or J-43897-12) and apply anti-
seize lubricant.
Do not over torque air fuel ratio sensor. Doing so may cause damage to air fuel ratio sensor,
resulting in the “MIL” coming on.

INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 4 jour-
nals of camshaft.
CAUTION:
Do not support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
three locations.
2. Set a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the
camshaft runout on a dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height with a micrometer.
2. If wear exceeds the limit, replace camshaft.
Camshaft Journal Oil Clearance
CAMSHAFT JOURNAL DIAMETER
Measure the outer diameter of camshaft journal with a microme-
ter.
CAMSHAFT BRACKET INNER DIAMETER
Tighten camshaft bracket bolt with the specified torque. Refer to EM-89, "INSTALLATION" for the tighten-
ing procedure.

TRANSVERSE LINK" .
Removal Work
1. Use a manual lift table caddy (commercial service tool) or equiv-
alently rigid tool such as a transmission jack. Securely support
bottom of suspension member and the transmission assembly.
CAUTION:
Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.
2. Remove rear engine mounting member bolts.
3. Remove front suspension member mounting bolts and nuts. Refer to FSU-6, "
FRONT SUSPENSION
ASSEMBLY" .
4. Carefully lower jack, or raise lift to remove the engine, the transmission assembly and front suspension
member. When performing work, observe the following caution:
CAUTION:
Confirm there is no interference with the vehicle.
Make sure that all connection points have been disconnected.
Keep in mind the center of vehicle gravity changes. If necessary, use jack(s) to support the vehi-
cle at rear jacking point(s) to prevent it from falling it off the lift.
Separation Work
1. Install engine slingers into front of cylinder head (right bank) and
rear of cylinder head (left bank).
