I'm sure every bull gear is different in all scopes. My scope dec has a
.010" run out which is pretty typical. Others might have considerable
less which the spring might not be needed. It is real easy to tell by
taking all the movement from the tilt plate and run the dec motor. If it
binds you better put the spring and loosen the adjustment. If you don't
have this problem, you don't need the spring. The spring takes the
runout of the bull gear and keeps the worm gear meshed. Sticktion on the
dec bearings cause, retrograde and the tight tilt plate and spring
prevents, backlash (If adjusted correctly).
