Remove 

1 

Remove the exhaust manifold assembly from the side of the engine where the engine mount is to be removed, 
refer to 

3.11  Exhaust Manifold Assembly

. 

2 

Fit the engine lift brackets, Tool No. EN-46114 (1) to 
the cylinder heads. 

CAUTION

 

Only lift the engine far enough to take the 
weight off the engine mount, or damage to 
the mount and lifting equipment failure may 
occur. 

3 

Using an engine lifting crane, raise the side of the 
engine where the mount is to be removed enough to 
remove the weight from the engine mounts, and 
create a slight tension in the lifting equipment. 

 

 

Figure 6A1 – 404

Inspect 

N O T E  

Although the following procedure provides 
information regarding on-vehicle engine mount 
inspections, it is preferable to inspect the engine 
mounts once removed from the vehicle. 

1 

Fit the engine lift brackets, Tool No. EN-4611 to the cylinder heads. 

 

Only lift the engine enough to take the weight 
off the engine mounts, or damage to the 
mounts and lifting equipment failure may 
occur. 

2 

Using a commercially available engine lifting crane, have an assistant raise the engine far enough to remove the 
weight on the engine mounts and create a slight tension in the rubber. 

3 

Observe the engine mount while raising the engine.

Replace the engine mount if any of the following conditions are found: 

• 

The hard rubber surface is covered with heat check cracks, 

• 

The rubber is split through the centre of the engine mount, or 

• 

The rubber is separated from the metal plate portion of the engine mount. 

 

5 

Remove the engine lift brackets, Tool No. EN-46114 from the engine. 

Reinstall 

The reinstallation procedure for the engine mounts is the reverse of the removal procedure, noting the following: 

 

Ensure all fasteners are tightened to the correct torque specification.
