Quote:The slop (which is backlash between the worm and wheel) can be adjusted in one of two ways depending on what mount you have (older or newer). To make the adjustment on the older mounts you have to remove the worm/motor housing. Beneath the motor are 3 allen head bolts and 4 allen head set screws. The bolts pull the worm and wheel together while the set screws push them apart. In addition, the arrangement of the set screws also effects the tilt of the worm assembly.On newer mounts where the RA worm assembly is spring mounted, some adjustment may be made without removing the housing by simply turning the large brass adjustment screw on the housing. However, there are a couple of other screws that limit the inward and outward movement of the worm assembly that may also need adjustment. These, particularly the bottom one require removal of the housing.Adjustments should be made with the axis slewing so that you can hear the meshing of the worm and wheel. They are done easiest with the clutches released on the RA. The adjustments on either system can be confusing and difficult until you get a sense of what they do. You can easily make things worse so plan to spend a little time on this.
