shaft (3) by hand. If end float is higher than 0.012",
insert shim between input shaft (3) and rear
bearing (7). Repeat until end float is less than
0.012". Check rotational torque by hand. The
torque should be less than 2.2 lbs-inch.
15. Check that the gear backlash is between 0.006"
and 0.016". You should not have to adjust the
backlash.
