• When installing brake discs, brake plates and clutch
backing plate, refer to “Center Support Components:
”.
• Install clutch backing plate (1) with its flat side facing
brake disc.
• After installing each retaining backing plate ring,
measure movement of brake piston again.
If it is not within standard range, it is possible that ring
is not installed properly. Then disassemble and
reassemble again.
Standard movement of second coast brake piston
and second brake piston
Second coast brake piston: 1.00 – 1.20 mm (0.039
– 0.047 in.)
Second brake piston: 1.01 – 2.25 mm (0.040 –
0.089 in.)

• Measure inside diameter of planetary sun gear
bushing. If inside diameter exceeds limit, replace
planetary sun gear.
