CAUTION: HANDLE WITH CARE.
To ensure our customers receive all components with full integrity, we pack the motors separate from their Linkage assemblies. This requires that the installer position and fasten the motor before continuing with the install. Please follow the instructions below and handle the assembly carefully.
CAUTION: Dropping the assembly or any excessive impact MAY cause damage to the motor.
Instructions:

  1. Position the gear cover in place as shown if not already in place.
  2. Seat motor into position on the three mounting bosses. This may require an adjustment of the gear by moving the swing arms.
  3. After seating into place, fasten the motor with the three motor mount screws with 4mm Hex Head. Tighten screws to 36 in-lbs (4N-m). Do not over torque.

Installing Linkages (Driver Side)

AMP Research 76255-01A Running Board Assembly - parts3Install the Idler linkage in the First mount position at the front of the truck, for Passenger and Driver sides, using the bolts supplied (13). All plastic or rubber hole plugs need to be removed that are next to the linkage mounts. Also, an extra vertical seam-sealer bead may need to be removed from the front linkage mounting surface. Torque fasteners to 16 ft- lbs. (22 N m).
Rear Linkage (Motor Linkage)AMP Research 76255-01A Running Board
Assembly - parts4 Assemble the motor to the linkage like the picture before installation shown on page 2. Position the motor so the linkage is in the mid extension position. This way the lower bolt can still be installed.
Install the motor linkage with provided Conical washer bolts (13) in the second to last set of holes, approximately 16” from rear of cab. Note: On some models these holes are not present. If so use next set of holes forward. Approximately 33” from rear or cab. Keep the linkage held up to the angled surface and the vertical surface. Some structural adhesive remnants may need to be chipped off at the rocker seam. Torque fasteners to 16 ft-lbs. (22 N m).
Installing Linkages (Passenger Side)
Rear Linkage (Motor Linkage)
Install the Motor linkage on the passenger side in the second to last set of holes from the rear. The motor should be facing the front of the vehicle for this side as well. Follow the same step as on the Driver side in the previous step.
Torque fasteners to 16 ft-lbs. (22 N m). Slide the front mounting T-nut into position, place the board(1) about 5 to 6 inches from the front edge of the front door. Use fasteners(11) to attach boards, finger tighten only. Align the rear T-nut and bolt it to the rear linkage. Then tighten all 4 fasteners to 10 ft-lbs.

Congratulations on your purchase of the genuine AMP Research PowerStep!
Here’s what you should know…
POWER-DEPLOYABLE RUNNING BOARDS OPERATION: AMP Research PowerStep running boards automatically move when the doors are opened to assist entering and exiting the vehicle.
Automatic power deploy:
The running boards will extend down and out when the doors are opened.
Automatic power stow:
The running boards will return to the stowed position when the doors are closed. There will be a 2-second delay before the running boards move to the stowed position.
Automatic stop:
If an object is in the way of the moving running board, the running board will automatically stop.
To reset, clear any obstruction, then simply open and close the door to resume normal operation.
AMP Research 76255-01A Running Board Assembly -
parts23Manually set in the deployed (OUT) position for access to the roof:
The running boards can be manually set in the deployed position by firmly holding the step down with your foot while at the same time closing the door. To resume normal operation, open and close the door.
Maintenance: In adverse conditions, debris such as mud, dirt, and salt may become trapped in the running board mechanism, possibly leading to unwanted noise. If this occurs, manually set the running boards to the deployed position and flush the front and rear hinge arms with a high-pressure car wash wand.
Avoid spraying the motors directly. After washing, apply silicone spray jubricant to the hinge pivot pins.
Do not apply silicone, wax or protectants like Armor All® to the running board stepping surface.
Caution! Keep hands away when the running board is in motion.
