Basic instructions – Shop and assembly
Shimming
For each adjustment operation, select adjusting shims and measure the adjusting shims individually using a micrometer,
then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or
the rated value shown on each shim.
Rotating shaft seals
For correct rotating shaft seal installation, proceed as follows:
1. Before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes.
2. Thoroughly clean the shaft and check that the working surface on the shaft is not damaged.
3. Position the sealing lip facing the fluid.
NOTE: With hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that
they will move the fluid towards the inner side of the seal.
4. Coat the sealing lip with a thin layer of lubricant (use oil rather than grease). Fill the gap between the sealing lip
and the dust lip on double lip seals with grease.
5. Insert the seal in its seat and press down using a flat punch or seal installation tool. Do not tap the seal with a
hammer or mallet.
6. While you insert the seal, check that the seal is perpendicular to the seat. When the seal settles, make sure that
the seal makes contact with the thrust element, if required.
7. To prevent damage to the seal lip on the shaft, position a protective guard during installation operations.
