B-Clutch Measurement

WARNING: This page is about a different variant/trim than selected.

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

Measurement (special tool #8901A, Pressing Tool), (special tool #10429, Gauge, Force)

Place the B-clutch, with the wave plate on top, on a suitable arbor press.
Position tools (special tool #8901A, Pressing Tool) (3) (using just the cross bar) (3) and (special tool #10429, Gauge, Force) (2) on top of the B-clutch wave plate (1) and under the press ram.

Apply 500 N (112 lbs.) of downward force on the B-clutch to compress the wave plate.
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.

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.

Using a suitable depth micrometer, measure the B-clutch piston.
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.
