Section 12 (Starting/Charging Systems (H4SO)): Generator: Inspection: Brush
WARNING: This page is about a different car, the 2006 Subaru Outback and 2006 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.
- Measure the length of each brush. Replace the brush if wear exceeds service limits. There is a service limit mark (A) on each brush.
Brush length:
Service limit (1)
5.0 mm (0.197 in)
Standard (2)
18.5 mm (0.728 in)
- Check that there is appropriate pressure on the brush spring.
Using a spring pressure indicator, push the brush into the brush holder until its tip protrudes 2 mm (0.08 in). Then measure the pressure of brush spring. If the pressure is 2.2 N (224 g, 7.91 oz) or less, replace the brush spring with a new part. 4.8 - 6.0 N (489 - 612 g, 17.26 - 21.58 oz) pressure is required on the new spring.
