ENGINE ASSEMBLY
Revision: 2006 January2006 M35/M45
When installing engine mounting bracket (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).
Install engine mounting bracket (RH) (lower) as follows:
–Temporarily tighten mounting bolts (shown as “C”, “D” and “E” in
the figure).
–Tighten mounting bolts to the specified torque with following
mounting surfaces touched.
• Engine mounting bracket (RH) to engine mounting bracket (RH)
(lower) (shown as “C” and “D” in figure).
• Front final drive to engine mounting bracket (RH) (lower) (shown
as “E” in figure).
Make sure all engine mounting insulators are seated properly,
then tighten mounting nuts.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following 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.
Bleed air from lines and hoses of applicable lines, such as in cooling system.
After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.

becoming magnetized.
3. Lift the engine with hoist to install it onto the widely use engine stand.
CAUTION:
Use an engine stand that has a load capacity [220 kg (441 lb) or more] large enough for supporting
the engine weight.
If the load capacity of the stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning the stand.
–Remove intake manifold collector. Refer to EM-19, "INTAKE MANIFOLD COLLECTOR" .
–Remove intake manifold. Refer to EM-24, "INTAKE MANIFOLD" .
–Remove fuel injector and fuel tube assembly. Refer to EM-45, "FUEL INJECTOR AND FUEL TUBE" .
–Remove ignition coil. Refer to EM-42, "IGNITION COIL" .
–Remove rocker cover. Refer to EM-51, "ROCKER COVER" .
–Remove exhaust manifold. Refer to EM-26, "EXHAUST MANIFOLD" .
–Other removable brackets.
NOTE:
The figure shows an example of widely use engine stand that
can hold mating surface of transmission with drive plate
removed.
CAUTION:
Before removing the hanging chains, make sure the
engine stand is stable and there is no risk of overturning.
