Control Shaft :
Standard units are shipped with a control knob for manual phase adjustments. The control shaft, a keyed shaft extension, may be ordered as an option and installed in place of the standard knob.

The control shaft may then be used to mount a control motor or flexible shaft assembly. The control shaft may be installed on the knob side, the lock side, or on both sides of the Differential.

Control Motor:
The control motor option provides the capability of remote or automatic position control. The control motor is directly mounted to the Differential in place of the control knob.
The motor may be mounted on either side of the differential, or it may be mounted above the Differential using the control motor mounting bracket. Variable correction rates are available.

Right Angle Gearbox :
Right angle gearboxes are available in a 1:1 gear ratio for the DIFF 1, 7 and 20 HP units. The shafts may rotate in either direction.

The gearboxes may be mounted directly to either side of the Differential in a variety of positions and configurations including single or through-shaft options.

Shaft Reversing Gearbox :
The SR (Shaft Reversing) gearbox may be mounted to either side of the Differential in a variety of positions and may be used as the input or output element. The SR box is available for all sizes in either a 1:1 or 2:1 ratio.

The primary purpose of the SR box is to provide a same-direction rotation of the input and output shafts. The 2:1 ratio SR box may be used as either a speed reducer or speed increaser.
