a.

Measure dimensions “K” and “L”, and calculate dimension “J”.

i.

Measure dimension “K” between the converter housing fitting
surface of transmission case and the needle bearing mating sur-
face of under drive sun gear.

CAUTION:

Never change the straight edge installation position before
the completion of “L” measurement.

ii.

Measure dimension “L” between the converter housing fitting
surface of transmission case and the oil pump fitting surface of
transmission case.

iii.

Measure dimension “K” and “L” in at least three places, and take
the average.

iv.

Calculate dimension “J”.

b.

Measure dimensions “M

1

” and “M

2

”, and calculate dimension

“M”.

49. Adjustment of front brake clearance “C”.

• Measure clearance between front brake piston (1) and front

brake retaining plate (2).

• Select proper thickness of front brake retaining plat so that

clearance is within specifications.

a.

Measure dimensions “O” and “P”, and calculate dimension “N”.

i.

Measure dimension “O” between the converter housing fitting
surface of transmission case and the front brake retaining plate.

CAUTION:

Never change the straight edge installation position before
the completion of “P” measurement.

ii.

Measure dimension “P” between the converter housing fitting
surface of transmission case and the oil pump fitting surface of
transmission case.

iii.

Measure dimension “O” and “P” in at least three places, and
