4. Select the friction disc & plate so as to satisfy the
following equation:
{(A-B)+C}-(D+E)=0.06-0.20mm (0.002-0.008in)
Also, the total size difference of the friction disc &
plate and spring disc should be 0.05mm (0.02in) or
less.

2. Measuring the dimension between the thrust washers
at both ends.
Assemble the side gear, pinion, pinion shaft,
pressure ring and thrust washer, and pressing the
pressure ring to–the pinion shaft in the direction of
the shaft to make the clearance 0.
Have the side gear contact to the pinion to make the
backlash 0.
Measure the dimension (H) between thrust
washers at both ends.
