VERSION BT 85
As explained above, the brush motors mounted in the disk versions (BT 105, BT 85)
are very similar. Externally, they differ in the presence of the air conveyor, internally
they differ for the different carbon brushes.
The procedure for removing the carbon brushes on the BT 85 version is described
below.
Disassembly
1
To remove the protective metal band, proceed as for the previous motor D until you reach the carbon
brushes I.
2
Identify the crosshead screw I1 and unscrew it to disconnect the carbon brush I2.
3
With a hook (as for the previous motor) lift spring I3 and extract the carbon brush I2.
Checks
4
As well as checking the dimensions of the carbon brush I2, also check the state of wear of the rotor I4
(where it slides against the carbon brushes) and the contact surface of the carbon brushes I2. See the
indications for the previous motor.
5
Make sure all the electric wires connecting the carbon brushes are tightly fastened to their mounts and in
good condition and that the fixing screws I1 are screwed up tightly.
