1. Place the 2-6 brake, with the wave plate on top (4), on a suitable arbor press (1).
2. Position tools 10427 (3) and 10429 (2) on top of the 2-6 brake wave plate and under the press ram (1).

3. Apply 48.4 kg/cm² (688 lbf.) of downward force on the 2-6 brake to compress the wave plate.
4. Using a suitable linear caliper (2), measure the thickness of the compressed 2-6 brake (1) to calculate the 2-6 brake clearance in order to determine the correct select pressure plate (2) thickness.

   Record the measurement as (A)

5. Place a suitable straight edge (1) across the sealing surface of the transaxle housing.
6. Measure (3) the distance between the underdrive brake retainer (2) and the bottom of the straight edge (1) to calculate the 2-6 brake clearance in order to determine the correct select pressure plate thickness.

   Record the measurement as (B)

7. Positing the fluid pump on tool 8285 with the 2-6 brake piston (3) facing up.
8. Place a straight edge (1) across the 2-6 brake piston (3).
9. Measure (2) distance between the fluid pump sealing surface and the bottom of the straight edge to calculate the 2-6 brake clearance in order to determine the correct select pressure plate thickness.

   Record the measurement as (C) 

Calculation 

Add measurement C to B and subtract A. The remainder is the clearance of the 2-6 brake. Refer to SPECIFICATIONS . If the clearance is not within specification, a thicker or thinner select pressure plate can be installed to achieve proper clearance.
