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.

When designing a motor control it is important to note that the maximum control shaft speed is 1800 RPM. Please consult the factory before designing a speed trimming system.
