along one face of each brush. When the
brushes are worn down to these marks, they
are worn out and must be renewed. If no
marks are provided, measure the length of
each brush (see illustration). No dimension is
given by Rover but as a rough guide 3.5 mm
should be regarded as a minimum. If any
brush is worn below this amount, renew the
brushes as a set. If the brushes are still
serviceable, clean them with a solventmoistened
cloth. Check that the brush spring
pressure is equal for all brushes and holds the
brushes securely against the commutator. If in
doubt about the condition of the brushes and
springs, compare them with new
components.
8 Clean the commutator with a solventmoistened
cloth, then check for signs of
scoring, burning, excessive wear or severe
pitting. If worn or damaged, the commutator
should be attended to by an auto-electrician.
Refitting
9 On refitting, slot the positive brushes into
position in the brush holder then refit the
insulating plate, ensuring that the small
threaded brackets are correctly positioned on
the brush holder and locate with the pins
on the insulating plate.
10 Fit the brush holder assembly to the
commutator and slot the negative (field coil)
brushes into position in the brush holder. With
all the brushes in position, fit the brush
springs and secure them in position with the
retaining caps. Check that the brushes are
