7.Speed Controller Setup

1.Attach the Lower Connecting Rod Assembly to the Lower Bellcrank.

a.Attach Lower Connecting Rod Assembly to the Lower Bellcrank with a 3/8”-24 Nyloc Nut. Tighten using 9/16” and 1/2” wrenches.

c.If the Actuator does not work smoothly, binds up, or does not fully return to the “normal” position, loosen the Self-Locking Acorn Nut slightly and recheck the operation. Repeat as needed to achieve proper operation.

d.Depress the Reversing Lever and then press lightly on the Bail Handle until the Front Face of the Rear Slot on the Bail Handle just touches the Actuator Pin (also refer to picture in step ‘e’ below).

e.The Front Face of the Rear Slot and the Actuator Pin Bushing should be in contact with each other and appear as shown below:

2.Setup the Speed Controller Mechanism – Critical for proper operation.

a.Verify that the Self-Locking Acorn Nut is tightened sufficiently to hold the Upper Connecting Rod Assembly firmly in place. If not, slightly tighten the Self-Locking Acorn Nut.

b.Verify the Actuator reversing function by depressing the Reversing Lever (Red) and then releasing it. It should work smoothly and, when released, it should fully return to the “normal” position.

f.If the Actuator Pin does not enter into the Rear Slot as show below, the Upper Connecting Rod Assembly is too short and must be lengthened.

i.Remove the nut that holds the Rod End to the Upper Bellcrank.

ii.Disconnect the Rod End from the Upper Bellcrank.

iii.Adjust the Rod End outwards by unscrewing it counterclockwise.

iv.Reattach the Rod End to the Upper Bellcrank and secure it with the nut (hand tightened).

v.Repeat this adjustment as needed to position the Rear Slot and Actuator Pin as shown in step ‘e’ above.
