Chapter 1 – General Instructions:
IMPORTANT NOTICE:

• All maintenance and repair operations described in this manual should be carried out exclusively by authorised
  workshops. All instructions detailed should be carefully observed and special equipment indicated should be
  used if necessary.
• Everyone who carries out service operations described without carefully observing these prescriptions will be
  directly responsible of deriving damages.

SHIMMING:
At each adjustment, select adjusting shims, measure them individually using a micrometer and then sum up
recorded values. Do not rely on measuring the whole shimming set, which may be incorrect, or on rated value
indicated for each shim.
ROTATING SHAFT SEALS:
To correctly install rotating shaft seals, observe the following instructions:
– Let the seal soak into the same oil as it will seal for at least half an hour before mounting;
– Thoroughly clean the shaft and ensure that the shaft working surface is not damaged;
– Place the sealing lip towards the fluid. In case of a hydrodynamic lip, consider the shaft rotation direction and
orient grooves in order that they deviate the fluid towards the inner side of the seal;
– Coat the sealing lip with a thin layer of lubricant (oil rather than grease) and fill with grease the gap between
the sealing lip and the dust lip of double lip seals;
– Insert the seal into its seat and press it down using a flat punch. Do no tap the seal with a hammer or a drift;
– Take care to insert the seal perpendicularly to its seat while you are pressing it. Once the seal is settled,
ensure that it contacts the thrust element if required.;
– To prevent damaging the sealing lip against the shaft, place a suitable protection during installation.
