INTRODUCTION Basic instructions - Shop and assembly Shimming For each adjustment operation, select adjusting shims and measure 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 indicated on each shim. Rotating shaft seals For correct rotating shaft seal installation, proceed as follows: • Before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes. • Thoroughly clean the shaft and check that the working surface on the shaft is not damaged. • Position the sealing lip facing the fluid; with hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that they will deviate the fluid towards the inner side of the seal. • Coat the sealing lip with a thin layer of lubricant (use oil rather than grease) and fill the gap between the sealing lip and the dust lip on double lip seals with grease unless instructed otherwise. • 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. • While inserting the seal, check that it is perpendicular to the seat; once settled, make sure that it makes contact with the thrust element, if required. • To prevent damaging the seal lip on the shaft, position a protective guard during installation operations. O-ring seals Lubricate the O-ring seals before inserting them in the seats, this will prevent them from overturning and twisting, which would jeopardize sealing efficiency. Sealing compounds Apply one of the following sealing compounds on the mating surfaces when specified: SILMATE® RTV1473, or LOCTITE® RTV 598 or LOCTITE®INSTANT GASKET 587 BLUE. Before applying the sealing compound, prepare the surfaces as directed on product container or as follows: • Remove any incrustations using a metal brush. • Thoroughly de-grease the surfaces using a locally approved cleaning agent such as safety solvent or brake parts cleaner.
