Selecting The Reverse Gear Shims - Yamaha F50A Service Manual

Example:
If "M" is "22.45 mm" and "F" is "+5", then
T1 = 22.75 + (+5)/100 – 22.45mm
= 0.30 + 0.05 mm = 0.35 mm
If "M" is "22.45 mm" and "F" is "–5", then
T1 = 22.75 + (–5)/100 – 22.45mm
= 0.30 – 0.05 mm = 0.25 mm
3. Select the forward gear shim(s) (T1) as
follows.

Selecting the reverse gear shims

1. Measure the backlash to find the shim
thickness (T2). Add or remove shims if
out of specification. For measuring pro-
cedures, see "Measuring the forward and
reverse backlash" in this chapter.
