LOW AND REVERSE BRAKE ASSEMBLY

BUE051719500A12

1. Apply ATF to the new inner and outer seals, and install them onto the low and reverse brake piston.

Seal ring inner diameter
Inner seal: 156.5 mm {6.161 in}
Outer seal: 188.0 mm {7.402 in}

2. Face the outer seal lip toward the inside by gently rolling it down around the circumference for easier installation into the case.

3. Install the low and reverse brake piston by pushing evenly around the circumference, being careful not to damage the outer seal.

4. Install the spring and retainer component.

5. Install the SSTs in the transaxle case as shown.

Caution
• Depress the spring retainer and retainer component only enough to install the snap ring. Overpressing will damage the assembly edges.

6. Compress the spring and retainer.

7. Install the snap ring.

8. Remove the SSTs.

9. Install the wave spring with the buff finish downward.

10. Install the drive and driven plates in the following order.

Driven-Drive-Driven-Drive-Driven-Drive-Driven-Drive

11. Install the retaining plate.

12. Install the snap ring.

13. Measure the clearance between the low and reverse brake retaining plate and the snap ring. Make several measurements and calculate the average value.

• If the clearance is not within the specification, adjust it by selecting a proper plate from below.
Low and reverse brake clearance
1.5-1.8 mm {0.06-0.07 in}

Retaining plate sizes

mm {in}
6.8 {0.268}
7.0 {0.276}
7.2 {0.283}
7.4 {0.291}
7.6 {0.299}

Warning
• Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eye wear whenever using compressed air.
Caution
• Applying compressed air to the assembled clutch pack for longer than 3 seconds at a time will damage the seal. Do not apply compressed air for more than the aforementioned time when testing the system.

14. Inspect the low and reverse brake operation by applying compressed air through the fluid passage as shown in the figure.

Air pressure
390 kPa {4.0 kgf/cm2, 57 psi} max.
