GEAR BACKLASH ADJUSTMENT
This adjustment is performed in the case that the SLID motor assembly has
been removed and installed. It sets the amount of backlash between the slide
idler gear, mounted on this assembly, and the slide gear, mounted on the
carriage, so that it is appropriate, and so that both gears mesh smoothly during
a head height change after HP seek.
Adjustment: Loosen the screw shown in the figure below, then move the
motor assembly while checking the amount of backlash and
fasten it at the appropriate position.
Standard: At the level where the slide idler gear slides smoothly in the axial
direction.
