8.6. WEAR OF ALTERNATOR BRUSHES

Figure 8.6-1

Carry out the procedures described in paragraph
7.13. “Disassembling the alternator brushes”.

Inspect the 2 brushes for wear, referring to the
figures at left and to the descriptions below:

•

The brush shown in (A) has a correct wear
pattern.

•

The brush shown in (B) has an irregular wear
pattern which may result in noise and wear of
the alternator collector.

Using abrasive paper, smooth down the jagged
edges so that the brush appears as in figure (C).
