INSPECTION
Low and reverse brake snap ring and spring retainer
I Check for deformation, or damage.
Low and reverse brake return springs
ICheck for deformation or damage. Also measure free length
and outside diameter.
Inspection standard: Refer to SDS, AT-202.
Low and reverse brake drive plates
ICheck facing for burns, cracks or damage.
I Measure thickness of facing.
Thickness of drive plate: Standard value1.52 - 1.67 mm (0.0598 - 0.0657 in)
Wear limit 1.4 mm (0.055 in)
I If not within wear limit, replace.

Low one-way clutch inner race
ICheck frictional surface of inner race for wear or damage.
I Install a new seal rings onto low one-way clutch inner race.
I Be careful not to expand seal ring gap excessively.
I Measure seal ring-to-groove clearance.
Inspection standard: Standard value: 0.10 - 0.25 mm (0.0039 - 0.0098 in)
Allowable limit: 0.25 mm (0.0098 in)
I If not within allowable limit, replace low one-way clutch inner
race.
