Reassembly
1
To mount the new carbon brushes, perform the disassembly operations in reverse.
2
Before remounting the carbon brushes, compare the dimensions with those to be replaced. Only the
length should differ.
3
Make sure the carbon brushes slide freely in their housing H and the housing is not distorted or
dirty.
4
Blow the motor with a jet of compressed air, if possible holding it with the pinion downwards, to eliminate the
dust left by the carbon brushes themselves as they wear.
5
Always check the state of wear of the rotor I (where the carbon brushes G (G = G1+G2+G3+G4) slide).
6
Always check that the surface of the smooth pinion shaft B6 is free from marks or abrasion which could
compromise the seal of the seal ring F1.
7
Always check that the seal ring F1 is in good condition and positioned correctly in its housing on the
reduction unit F.
