(2) Calculate the reverse gear shim thick-
ness (T2).
NOTE:
“R” is the deviation of the lower case
dimension from standard. It is stamped on
the trim tab mounting surface of the lower
case in 0.01-mm units. If the “R” mark is
missing or unreadable, assume a “R” value
of “0”, and check the backlash when the
unit is assembled.
Example:
If M2 is “27.95 mm”, R is “+2”, then
T2 = 27.95 – 27.4 – (+2)/100 mm
= 27.95 – 27.4 – 0.02 mm
= 0.53 mm
Reverse gear shim thickness
(T2) = M2 – 27.4 – R/100
