Measuring steps
(1) Calculate the specified value (M0).
NOTE:
“F” 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 “F” mark is
missing or unreadable, assume an “F”
value of “0”, and check the backlash when
the unit is assembled.
Example:
If “F” is “+5”, then
M0 = 25.30 + (+5)/100 mm
= 25.30 + 0.05 mm
= 25.35 mm
If “F” is “–3”, then
M0 = 25.30 + (–3)/100 mm
= 25.30 – 0.03 mm
= 25.27 mm
Specified value (M0) =
25.30 + F/100 mm
