7.3 Alternator brush wear limit marks
(arrowed)
Inspection
3 In most cases, the brushes will have wear
limit marks in the form of a groove etched
along one face of each brush. When these
marks are erased by wear, the brushes are
worn out (see illustration). If no marks are
provided, measure the protrusion of each
brush from the brush holder end to the tip of
the brush. No dimension is given by Rover but
as a rough guide, 5.0 mm should be regarded
as a minimum. If either brush is worn to or
below this amount, renew the voltage
regulator and brush holder assembly. If the
brushes are still serviceable, clean them with
a solvent-moistened cloth. Check that the
brush spring pressure is equal for both
brushes and holds the brushes securely
against the slip rings. If in doubt about the
condition of the brushes and springs,
compare them with new components.
4 Clean the slip rings with a solventmoistened
cloth, then check for signs of
scoring, burning or severe pitting. If worn or
damaged, the slip rings should be attended to
by an auto-electrician.
Refitting
5 Refitting is the reverse of the removal
procedure.
