Starter Brush: Testing and Inspection

Measuring Brush Length:

1. Measure the brush length. If not within service limit, replace the armature housing and brush holder assembly.

Brush Length

Standard (New):

Nippondenso: 15.0 - 15.5 mm (0.59 - 0.61 in)
Mitsuba: 15.8 - 16.2 mm (0.62 - 0.64 in)

Service Limit: 10.0 mm (0.39 in)

NOTE: To seat new brushes after installing them in their holders, slip a strip of #500 or #600 sandpaper, with the grit side up, over the commutator, and smoothly rotate the armature. The contact surface for the brushes will be sanded to the same contour as the commutator.
