Installation Instructions
Mechanical Installation
Disconnect the existing handle shaft from the universal joint (shown in red) and clear the shaft
of scale and debris to the back of the bearing. Slide the quick release sprocket and drive assembly
onto the drive shaft and reconnect the drive shaft into the universal joint and tighten.
Figure 1
Slide the quick release sprocket and drive assembly up until they are behind the existing drive
shaft bearing. Be sure to allow 1/16” between the drive shaft bearing and quick release sprocket
and 1/8” between the drive assembly and the quick release sprocket. Rotate the drive assembly
counter clockwise 90 degrees and mark the location for the counter rotation hole (See figure 2).
Note: Existing locking mechanism may need removing or the drive can be positioned at another
angle from 90 degrees if necessary.

with the use or performance of the product or other damage with respect to any economic loss, loss of property, loss of revenue
or profit, or costs of removal, installation, or reinstallation.
Figure 2
Install the counter rotation bolt to secure the drive assembly. Washer spacers can be used to
take up any gap between the drive assembly and drive shaft bearing mount plate. The teeth on
the quick release sprocket and drive sprocket must be in line with one another (see figure 3).
Turn the quick release sprocket so allow drilling through the locking pin hole from both sides.
Drill 7/16” diameter hole approximately half the diameter of the drive shaft, then place the
retaining pin in the partially drilled hole to prevent the sprocket from turning and drill the drive
shaft from the other side. Note: this should keep the hole in line with the sprocket retaining hole.

Limit Sensor
The Trailer Chute Opener Limit Sensor adds greater flexibility to the Trailer Chute Systems by
allowing the operator to open and close the chute to any preset limit with confidence. The
included drive motor contains a built-in Hall Effect sensor that is used to count the rotations of
the motor. Once the chute reaches either limit, the corresponding yellow Limit LEDs will
illuminate and the chute will stop.
Avoid powering off the system while it’s operating as this may cause the limit sensor to
lose count, requiring you to reset the chute limits.
Setting the Close and Open Limits
From the Receiver/Drive keypad with the power “On”.
NOTE: Setting the CLOSE limit will preserve the distance between the open and close limit, while
setting the OPEN limit will change its position relative to the CLOSE limit. If you intend to set
both limits, set the CLOSE limit first. Only one limit may be set in the same operation sequence.
