1. Install the thrust bearing to the internal gear. NOTE: Face the temper color surface to the reverse brake side.
2. Measure depth “A” from the ST upper face to the washer mounting surface.
3. Measure the height “B” from the ST upper face to the mating surface of the drive pinion retainer.
4. Obtain the thickness of washer using the following formula to select the washer. T (mm) = A − B − (0.35 — 0.70) [T (in) = A − B − (0.014 — 0.028)] T: Washer thickness A: Depth from the ST upper face to the washer mounting surface B: Height from ST upper face to the drive pinion retainer mating surface 0.35 — 0.70 mm (0.014 — 0.028 in): Clearance
