Leaf spring inspection and repair

Leaf spring inspection and repair

To dismantle the leaf spring assembly remove the two side clips and the centre bolt. Thoroughly wash all parts and to inspect proceed as follows:

1. Inspect carefully to check that the leaves are not broken or show signs of cracking which, if evident, the leaf must be renewed. It should be noted that the third spring leaf is not available as a service replacement part which means that if this leaf is damaged the whole spring must be renewed.
2. Check that there is no paint or underseal present between the leaves which, if evident, must be removed.
3. Ensure that the mating surfaces of the leaves are perfectly smooth and clean. If there are signs of rusting or slight indentations, these areas must be cleaned using a file. Any deep indentations will be a source of weakness and the leaf must be renewed.
4. The 'estendblocks' are press fitted into the main leaf eyes and must be thoroughly inspected for excessive wear, signs of seizure and dry operation of the rubber parts. The 'estendblocks' should be renewed if there is any doubt as to their condition. To remove and replace the 'estendblocks' use Fiat .drift A.66056 or a suitably sized drift as shown in FIG 8:8.
5. Check the condition of all rubber pads, the centre buffer and the polyethylene linings for signs of wear, cracking or splits and, if evident, new parts must be fitted.
6. Once the spring has been reassembled it should be tested by loading as shown in FIG 8:5.
