INSTALLATION
Installation is in the reverse order of removal.
Note the following during installation:
• When installation directions are specified, install parts according to the directions. Refer to EM-197, "
Com-
ponent".
• Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insu-
lator.
• Prior to installing the upper torque rod, apply a light coat of silicone lubricant (A) to the washer facing side of the bushing inner tube as
shown.
NOTE:
• Apply silicone lubricant (A) by dabbing the outward facing tubesurface with a sponge or suitable tool.
• Do not apply excess lubricant.
• Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.
• Tighten engine mounting insulator (RH) bolts in the numerical order shown.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
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 leak- age at connection points.
• Start engine. With engine speed increased, che ck 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 gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.
