Install the disc to DT 46478 (1). See Special Tools .
Using the disc thickness gage, determine thickness ME for the disc set clutch B, without adjusting the disc, which is located in the second highest plate.
Calculate the test dimension PB - PB = EB - MB
EB = installation space

MB = disc set thickness

EXAMPLE

EB = 14.37 mm (0.566 in)

MB = 11.3 mm (0.445 in)

PB = 3.07 mm (0.121 in)
Find the disc set thickness. Refer to Transmission General Specifications .
PB is 3.07 mm (0.121 in), so the disc set thickness is 1.8 mm (0.070 in).
Replace clutch B setting disc 1.8 mm (0.070 in).
