B-Clutch Measurement

When the B-clutch is replaced, the proper selectable shim must be installed to achieve specified clearance.

1. Place the B-clutch, with the wave plate on top, on a suitable arbor press.
2. Position tools

3. Apply 500 N (112 lbs.) of downward force on the B-clutch to compress the wave plate.
4. Using a suitable micrometer, measure the thickness of the compressed B-clutch (3).

   Record the measurement as (A) 

   to calculate the B-clutch clearance in order to determine the correct selectable shim thickness.

5. With a suitable depth micrometer, place it at the mounting surface of the transmission oil pump (2) and measure to the base of the B-clutch retainer on the case (1). This measurement should be 61.05 mm.

   Record the measurement as (B) 

   to calculate the B-clutch clearance in order to determine the correct selectable shim thickness.

6. Using a suitable depth micrometer, measure the B-clutch piston.
7. Measure between the fluid pump sealing surface and the bottom of the straight edge.

   Record the measurement as (C) 

   to calculate the B-clutch clearance in order to determine the correct selectable shim thickness.

Calculation 

Take the case depth (B) subtract (C) subtract (A) remainder is the clearance of the B-clutch. If the clearance is not within specification a thinner or thicker reaction plate can be installed to achieve proper clearance.
