4.1.3. Storage
Before being mounted, the motor has to be stored in a dry place, without rapid or significant
temperature variations in order to avoid condensation.
If the GVM motor has to be stored for a long time, verify that the shaft end and the flange
are coated with corrosion proof product.
After a long storage duration (more than 3 month), run the motor at low speed in both
directions, in order to blend and spread the bearing grease.
The motor is delivered with caps for the water inlet and outlet to protect the cooling circuit.
Keep them on place until the motor commissioning.
4.2. Installation
4.2.1. Mounting
Vehicle frame must be even, sufficiently rigid and shall be dimensioned in order to avoid
vibrations due to resonance. Before tighten
ing the motor’s fittings, the foundation surface
must be cleaned and checked in order to detect any excessive height difference between the
fitting locations. In any case we recommend using shims to compensate small irregularities.
Caution: The user bears the entire responsibility for the preparation of the
foundation.
The table below gives the average tightening torques required regarding the fixing screw
diameter. These values are valid for both motor’s feet and flange bolting.
