ENGINE ASSEMBLY
Revision: 2006 December 2006 FX35/FX45
Separation Work
1. Change engine slinger installing to cylinder head (right bank). NOTE:
In order to keep secure position when hoisting engine.
2. Remove engine mounting insulators (RH and LH) under side nut with power tool.
3. Lift with hoist and separate engine and transmission assembly from front suspension member. CAUTION:

Before and during this lifting, always make sure that any harnesses are left connected.

Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
4. Remove alternator. Refer to SC-20, "
CHARGING SYSTEM" .
5. Remove starter motor. Refer to SC-8, "
STARTING SYSTEM" .
6. Separate engine from transmission assembly. Refer to AT- 2 6 9 , "
Removal and Installation (AWD Models)"
.
7. Remove front final drive from engine. Refer to FFD-13, "
FRONT FINAL DRIVE ASSEMBLY" .
8. Remove engine mounting insulators (RH and LH) and brackets (RH and LH) from engine with power tool.
9. Remove engine rear member and engine mounting insulator (rear) from transmission.
INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine mounting insulator to be damage and careful no engine oil gets on it.

For a location with a positioning pin, insert it securely into hole of mating part.

For a part with a specified installation orientation, refer to component figure in EM-243, "Removal and
Installation" .

When installing engine mounting brackets (RH and LH) on cylin-
der block, tighten two upper bolts (shown as “A” in the figure)
first. Then tighten two lower bolts (shown as “B” in the figure).
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant. Slinger bolts:

Tighten main muffler mounting bracket bolts in numerical order
as shown in the figure.
CAUTION:

Always replace exhaust tube gaskets with new ones when reassembling.

If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat
insulator, remove them.

When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.

Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.

Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.
INSPECTION AFTER INSTALLATION

Make sure clearance between tail tube and bumper is even.

With engine running, check exhaust tube joints for gas leakage and unusual noises.

Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.
