SHIMMING
For each adjustment operation, select adjusting shims, individually measure using a micrometer, then add up the
recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, and do not rely on the
rated value indicated on each shim.
ROTATING SHAFT SEALS
For correct rotating shaft seal installation, proceed as follows:
• Before assembly, allow the seal to soak for at least thirty minutes in the oil it will be sealing.
• Thoroughly clean the shaft, and check that the working surface on the shaft is undamaged.
• Fit the lip seal toward the fluid. If you are fitting a hydrodynamic lip seal, the grooves should be oriented so that the
fluid is directed toward the inner side of the seal (take the shaft direction of rotation into consideration).
• Coat the lip seal with a thin layer of lubricant (use oil rather than grease), then fill the gap between the lip seal and
the dust lip seal of the double-lip seals with grease.
• Insert the seal into its seat and press down using a flat punch. Do not tap the seal with a hammer or mallet.
• During assembly, make sure that the seal is fitted perpendicularly to its seat. Once this operation is completed,
check to make sure that the seal is in contact with the bearing stop, if required.
• To prevent damaging the lip seal on the shaft, fit an appropriate protective guard during installation.
"O" RINGS
Lubricate the "O" rings before fitting them into the seats. This prevents them from overturning and twisting, which
would make them ineffective.
SEALING COMPOUNDS
Apply one of the following sealing compounds to the mating surfaces marked with an X: Silmate RTV, Rhodorsil
CAF 1, or Loctite Plastic Gasket. Before applying the sealing compound, prepare the surfaces as follows:
• Remove any dirt using a metal brush.
• Thoroughly degrease the surfaces using one of the following cleaning agents: trichloroethylene, gasoline, or a
water and soda solution.
SPLIT PINS
When fitting split pins, make sure that the pin notch is positioned in the direction of the force required to stress the
pin. Spiral split pins do not require special positioning.
