INTRODUCTION
Basic instructions
Battery
Before carrying out any kind of service operation disconnect and isolate the battery negative lead, unless otherwise
requested for specific operations (e.g: operations that require the engine running). Once the specific operation has
been completed, disconnect the lead in order to complete the operation.
Shimming
For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add up
the recorder values: Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value
indicated for each on 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.
− Smear 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.
− Insert the seal in its seat and press down using a flat punch; do not tap the seal with a hammer or mallet.
− Whilst inserting the seal, check that the 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 jeopardise sealing efficiency.
Sealing compounds
Apply one of the following sealing compounds on the mating surfaces marked with an X: L
® 518™ , L
®
OCTITE
OCTITE
5205.
Before applying the sealing compound, prepare the surfaces as follows:
− Remove any incrustations using a wire brush.
−Thoroughly de-grease the surfaces using one of the following cleaning agents: trichlorethylene, petrol or a water
and soda solution.
Bearings
When installing bearings it is advised to:
− Heat the bearings to 80 - 90 °C before fitting on the shafts.
− Allow the bearings to cool before installing them from the outside.
Spring pins
When fitting split socket elastic pins, ensure that the pin notch is positioned in the direction of the force required to
stress the pin.
Spiral spring pins do not require special positioning.
Spare parts
Use genuine parts only.
Only genuine spare parts guarantee the same quality, duration and safety as they are the same parts that are assem-
bled during production.
Only genuine parts can offer this guarantee.
When ordering spare parts, always provide the following information:
