GENERAL INSTRUCTIONS:

IMPORTANT NOTICE:

All maintenance and repair operations described in this manual should be carried out exclusively by the authorized 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 direc- tives will be directly responsible for resulting consequences.

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 the 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 the gap between the sealing lip and the dust lip of double lip seals with grease;
• Insert the seal into its seat and press it down using a flat punch. Do not tap the seal with a hammer or a drift;
• Take care to insert the seal perpendicular 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.

O RINGS:

Lubricate the O rings before inserting them into their seats. This will prevent the O rings from roll over and twisting during mounting, which will jeopardize sealing.

SEALERS:
Apply silicone/gasket eliminator over the mating surfaces marked with an X. Before applying the sealer, prepare the surface as follows:
• remove possible scales using a metal brush;
• thoroughly degrease the surfaces using one of the following cleaning agents: trichlorethylene, diesel fuel or a water and soda solution.
