REFER TO GARAGE DOOR OPENER MANUAL FOR DETAILED INSTALLATION,

ADJUSTMENTS, AND SAFETY INFORMATION.

To prevent possible SERIOUS INJURY or DEATH:

• Disconnect ALL electric and battery power BEFORE performing ANY service

or maintenance.

The garage door MUST be in the fully closed position during installation.

Figure 2

Figure 1

BEFORE YOU BEGIN:

• The trolley must be in down (closed door) position during assembly and

installation. If you have a completely installed garage door opener, the rail/

opener assembly must be taken down. The UP and DOWN travel must be

readjusted after installation.

• Opener hanging brackets will require repositioning and the addition of an extra

bracket for stability due to increased rail length.

• This may require two people for installation.

IF THIS IS A NEW INSTALLATION:

Use the front (header) rail section, belt assembly, and longer emergency release

rope in this kit in place of those packaged with the garage door opener. Complete

the assembly, installation, and adjustment of the opener according to the garage

door opener manual. Ensure that an additional hanging bracket is added for

stability, as detailed below.

IF THIS IS AN EXISTING INSTALLATION, CONTINUE AS FOLLOWS:

1. Pull down on the emergency release handle, then disconnect the trolley from

the door arm.

2. Disconnect the rail/opener assembly from the header bracket and hanging

brackets, and place it on the floor.

3. Remove the sprocket cover from the opener sprocket and set aside.

4. Disconnect the master link from the trolley threaded shaft and belt; discard

(Figure 1).

5. Remove the spring/nut from the trolley and discard.

6. Remove idler pulley assembly and set aside.

7. Remove the belt assembly and discard.

8. Push the trolley back toward the opener. Disconnect the front rail section by

using a screwdriver tip to pry up the outer tab on each side of the rail, then

slide it off the center rail. Discard the front rail .(Figure 2)

9. Align the new front rail with the existing rail assembly, keeping the cut out

“window” at the front (header) end. Be sure to keep it right side up: the idler

pulley bolt hole above the window is larger on top of the rail than on the

bottom. Slide the front rail onto the assembly; tabs along the side will lock

into place.

10. As a temporary stop, insert a screwdriver into the hole 10" (25 cm) from the

front end of the rail ). Slide the trolley assembly to this point.(Figure 1

11. Lay the new belt beside the rail. Grasp the end with the hooked trolley

connector and pass approximately 12" (30 cm) of belt through the window.

Keeping the ribbed side toward the rail, and allow it to hang while you

complete the next two steps.

12. Replace the idler pulley, lock washer and nut. Rotate it to be sure it spins

freely. Grease the center if necessary.

13. Locate the rail tab. Use a flathead screwdriver and lift the rail tab until the

tab is vertical (90°) . (Figure 2)

14. Pull the belt around the idler pulley and hook the trolley connector into the

retaining slot on the trolley . The ribbed side must contact the (Figure 1)

pulley.

15. With the trolley against the screwdriver, dispense the remainder of the belt

along the rail length toward the motor unit and around the sprocket

(Figure1). The sprocket teeth must engage the belt.

16. Check to make sure the belt is not twisted, then connect it to the flat end of

the trolley threaded shaft with the master link :(Figure 1)

• Push pins of master link bar through holes in end of belt and trolley

threaded shaft.

• Push master link cap over pins and past pin notches.

• Slide clip-on spring over cap and onto pin notches until both pins are

securely locked in place.

17. Insert the trolley threaded shaft through the hole in the trolley. Be sure the

belt is not twisted, and the ribbed side faces the rail.

18. Hold the belt at the trolley shaft as you thread the spring nut by hand

(Figure3) onto the shaft until finger tight against the trolley. Do not use any

tools.

19. Remove the screwdriver.

20. Insert a flathead screwdriver tip into one of the nut ring slots and brace it

firmly against the trolley.

21. Tighten the spring trolley nut with an adjustable wrench or a 7/16" open end

wrench about a quarter turn until the spring releases and snaps the nut ring

against the trolley. This sets the spring to optimum belt tension . (Figure 3)

22. Replace the sprocket cover. Refer to your garage door opener manual to

complete the assembly, re-installation and adjustment of your opener. NOTE:

Before hanging the opener, an additional hanging bracket is necessary for

stability.

23. Replace the old emergency release rope with the new, longer replacement

rope.

24. Reconnect power.
