(3) Obtain the thickness of pinion height adjust-
ing washer to be inserted from the following for-
mula, and replace the temporarily installed
washer with this one.
T = To + N – (H × 0.01) – 0.20 mm (0.0079 in)
NOTE:
Use copies of this page.
T Thickness of pinion height adjusting washer mm (in)
To Thickness of washer temporarily inserted mm (in)
N Clearance of thickness gauge mm (in)
H Figure marked on drive pinion head
Memo:
(Example of calculation)
To = 2.20 mm (0.0866 in) + 1.20 mm (0.0472 in)
= 3.40 mm (0.1339 in)
N = 0.23 mm (0.0091 in)
H = + 1
T = 3.40 mm (0.1339 in) + 0.23 mm (0.0091 in)
– 0.01 mm (0.0004 in) – 0.20 mm (0.0079 in) =
3.42 mm (0.1346 in)
Result: Thickness = 3.42 mm (0.1346 in)
Therefore use washer 383605200.
