3.7 INSPECTION, VIBRATION DAMPER

1.

Check the reference lines. The reference 

lines should form a single line.

Inspect the rubber part for damage or 

degradation. If the rubber part shows cracks 

or if there are bits of rubber missing, the 

vibration damper must be replaced.

3.8 INSPECTING THE CYLINDER HEAD

1.

Check the sealing plugs and expansion 

plugs of the cylinder head for leaks. If 

necessary, pressure-test the cylinder head.

2.

Inspect the cylinder head for damage to the 

sealing surface and any cracks.

3.

Check the cylinder head for smoothness 

using a straight edge and feeler gauge. See 

"Technical data".

Note:

The cylinder head must be replaced if it does 

not meet the specified values.

4. REMOVING AND INSTALLING

4.1 REMOVAL AND INSTALLATION, ENGINE

Suspend the engine securely from 

the hoist, using approved lifting 

gear. 

Various fluids will be released when 

fluid pipes are removed. 

Collect these fluids. Personal safety 

and the risk of fire should always be 

considered.

Note:

Because of the large number of vehicle 

specifications, it is not feasible to exactly specify 

the engine removal and installation procedures 

for every vehicle.

This description only includes the most important 

points requiring attention.

-

Disconnect the earth lead from the battery 

terminal.

-

Avoid opening fluid systems as much as 

possible. If possible, remove and set aside 

the engine components.

-

When removing the engine, ensure that no 

parts or dirt fall into the engine, radiator or 

other components. All openings that are 

freed should therefore be plugged.

-

Wiring harnesses are vulnerable. If 

damaged, they may cause failures. Make 

sure these wiring harnesses are not live and 

are clear of moving parts.

-

Fit all attachment bolts and tighten them to 

the correct torque.

-

The engine should not be allowed to rest on 

the oil sump. Because the oil sump is made 

of sheet material, it will be severely damaged 

by the engine's weight.

-

The engine should not be allowed to rest on 

the flywheel housing. It can easily be 

damaged by the engine's weight.
