19. Set the dial indicator (A) against the output
driveshaft spline groove; then rock the driveshaft
slightly until gear lash (play) is taken out in one
direction (do not let driven shaft turn). Zero the
dial indicator and rock the shaft in the opposite
direction until gear contact is made. The new
reading is the backlash. It should be between
0.05-0.11 mm (0.0020-0.0043 in.).

NOTE: To decrease backlash, decrease the thick-
ness of shims (7). To increase backlash, increase
the thickness of shims (7). Make small changes at
a time.
