4. DISASSEMBLY AND ASSEMBLY

4.1 DISASSEMBLY AND ASSEMBLY, SPRING ASSEMBLY

Note:

Replacing only the broken spring leaf is not

recommended. All spring leaves in the assembly

were pre-settled together, to enable an even load

distribution across all spring leaves.

A new spring leaf will not have been pre-settled

and therefore does not carry an equal part

(usually a larger part).

If the spring leaf fracture was the result of ageing

or overloading, it is recommended to replace the

leaf spring assemblies on both sides. Otherwise,

the difference in spring opening between the two

sides could become too large, which would result

in misalignment of both the vehicle and the axle.

Renewal of parabolic spring leaves is strongly

advised against. Renewal is only allowed if the

supplier of the single spring leaf also is the

supplier of the spring assembly.

Disassembling spring assembly
1.

Disassemble the spring assembly.

2.

Clamp the spring assembly in such a way,

e.g. using two screw clamps, that it will stay

together when the centre bolt is removed

(avoid damage).

3.

Remove the clamping bolt from both spring

shackles.

4.

Remove the centre bolt. Note the position of

the centre bolt.

5.

Carefully release the pressure on the

assembly.

6.

Take the spring assembly apart.

Assembling spring assembly
1.

Neighbouring spring leaves should also be

replaced if they are damaged. This means a

complete assembly for a three-leaf parabolic

spring assembly. Check the other spring

leaves for damage. Replace these, if

necessary.

2.

Remove all rust from the remaining spring

leaves and treat them with zinc primer.

3.

Check the centre bolt for damage.

4.

Put together the spring assembly. The centre

bolt should not have any play in relation to

the spring assembly.

5.

Fit the centre bolt in the correct position and

tighten it.

6.

Fit the attachment bolts of the spring clamps.
