Selecting The Forward Gear Shims - Yamaha E60HWD Service Manual

Example:
If "M3" is 32.10 mm and "P" is (–5), then
T3 = 32.10 – 31.50 – (–5)/100 mm
= 0.60 + 0.05 mm
= 0.65 mm
5. Select the pinion shim(s) (T3) as follows.

NOTE:
"F" is the deviation of the lower case dimen-
sion from standard. The "F" mark a is
stamped on the trim tab mounting surface of
the lower case in 0.01 mm units. If the "F"
mark is unreadable, assume that "F" is zero
and check the backlash when the unit is
assembled.
