REPLACING THE TRACTION WHEELS
(
ELEVAH 40 MOVE
)
If required, replace the wheels as follows:
1. Remove the locking screws ;
Put the service screws in the appropriate extraction
holes and fasten them until they enter freely;
2. At the start of release, alternately tighten the screws, in
order to undo the part of the wheel forced on the hub;
then tap it a few times with a hammer to extract it
completely.
Reassembly
1. Assemble the wheel and insert the locking screws;
2. Adjust the position of the wheel so that the screws and any reference pins can fit into their
housings; if the motor is running to facilitate centring the holes, use 2 threaded bars screwed
onto the crown gear;
3. Tighten with one turn at a time, alternately, until completely locked.
NOTE:
it is advisable to replace the wheel before the thickness of the tread drops below 5 mm.
TRANSMISSION MOTOR
(

Checking the condition of the motor
1. Unscrew the two M5 tie rods and extract the aluminium cap
complete with brush holder;
2. Use compressed air to eliminate carbon dust deposits on the
inner surfaces of the motor.
3. With manifold motors, check the length of the brushes and their
smooth movement in their housings.
Checking the brushes
Check smooth movement as well as length of the brushes to ensure good performance.

When replacing brushes, pay utmost attention to the welds.
Checking the manifold
If the surface of the manifold bears signs of burns, reduced diameter in relation to the brushes or
eccentricity, repeat turning and dressing of the surface and undercutting between the slats. Extract
the armature by first disassembling the electromagnetic
brake mounted on the opposite side and then removing the armature itself, while being careful of
any accidental impact caused by the flow of the magnets.
