TRANSMISSION MOTOR
Checking the condition of the motor left in the housing.
1. Remove the clamp from the manifold side support;
2. Use compressed air to remove carbon dust deposits on the internal surfaces of the brush side
support;
3. Check the manifold, the length of the brushes and the smooth movement of the latter in their
housings;
4. Using a 500-volt megohmmeter, measure the insulation resistance of the armature (terminals
A1 - A2) and field (terminals D1 - D2) to the casing, which must be higher than 0.1 m ; if it is
lower, lift the brushes and test the field and armature again separately to check whether one or
both are damaged. In this case, remove the motor if the manifold requires maintenance and the
brushes need to be replaced.
Checking the brushes
Check smooth movement as well as length of the brushes to ensure good performance.

When replacing the brushes, pay the utmost attention to the welds.
Checking the manifold
If the surface of the manifold bears signs of burns, reduction of the diameter in relation to the brushes
or eccentricity, repeat turning and dressing of the surface and undercutting between the slats.
NOTE: whenever maintenance is performed, it is recommended to replace all consumables,
considering these to also include the screws complete with washers and anti-loosening
treatment, the keys and the corrugated washers.
ATTENTION
FOLLOWING A STRONG COLLISION WE RECOMMEND A THOROUGH CHECK OF THE
CASTING OF THE REDUCER, THE WHEEL, GEARS AND BEARINGS
ATTENTION
RESTORING THE IP RATING DEPENDS ON CORRECT POSITIONING OF THE O-RINGS AND
SILICONE COATING OF THE TIE RODS. AFTER THE MAINTENANCE TECHNICIAN HAS
CLOSED THE MOTOR, THEY ARE FULLY RESPONSIBLE FOR THE IP RATING AND THE
INTEGRITY OF THE MOTOR.
