Remove Garage Door From Trolley

How to replace garage door chain

To remove your garage door from the trolley, first, you will remove the fastener ring. You will pull this from the straight door arm that is connected to the trolley. Next, pull out the clevis pin. Now, remove the garage door from the trolley.

5

Lower Arms

Now, you can gently drop the arms down to rest on the garage door.

6

Disconnect Wall Control And Safety Sensor Wires From Motor

You can gain access to the control and safety wires in the garage door opener by opening the light cover. When you find the control and safety sensor wires in your garage door motor, disconnect them before closing the light covering.

7

Remove Garage Door Motor From Ceiling

Remove all of the nuts, bolts, and washers holding the garage door opener in place on the bracket. Once you have removed the last bolt, carefully lower the garage door opener onto a ladder before finally lowering it all the way to the floor.

8

Lower Rail To The Garage Floor

Remove the fastener ring and the clevis pin from the header bracket, and then gently lower the rail down until it is resting on the garage floor.

9

Separate Outer Trolley From Inner Trolley

Just slide the two trolleys apart.

10

Remove Shaft From Trolley

First, remove the nut and lock washer, and then remove the shaft from the trolley.

11

Pull Chain From Motor Unit Sprocket And From Chain Spreader

Now, you will remove the chain from the motor unit sprocket. Also remove the chain from the chain spreader.

12

Remove The Chain Cable From The Rail Window

To remove the chain cable, you will first remove the master link clip-on spring from the master link cap on the trolley. Next, remove the master link bar and cap. Take off the idler pulley nut and the lock washer, and then, pull out the bolt. Now, you can remove the idler pulley from the rail window.

13

Disconnect The Chain And Cable Assembly

Remove the master link cap and bar to disconnect the trolley shaft from the chain and remove the chain and cable assembly

14

Prepare The New Chain And Assembly

Take time to lay out the new chain and assembly near the place it will be installed. Lay them on the garage floor and make sure you have all of the necessary pieces and hardware.

15

Thread About 12 Inches Of Cable Through The Rail Window

Push the cable into the rail window, threading about 12 inches through.

16

Place The Idler Pulley Into The Rail Window

Install the idler pulley on the rail window. The idler pulley should be located behind the chain cable. Then, ensure that the mounting hole is lined up. Now, secure the idler pulley by inserting the bolt and tightening it with the lock washer and nut.

17

Connect Chain Cable

Now it is time to connect your new chain to the retaining slot by pushing master link bar’s pins up through the cable link and trolley slot. Next, you will push the master link cap over the master link bar pins and past the pin notches.

18

Slide The Clip-on Spring Over The Master Link Cap

Slide the spring over the master link cap. Then, slide it onto the pin notches until you are sure both pins have been secured.

19

Align The Rest Of The Chain And Cable Assembly

Now, you will lead the cable onto the idler pulley. Then you will thread the chain into place through the chain spreader and around the motor sprocket.

20

Connect The Door’s New Chain With The Trolley Threaded Shaft

To connect the new chain and the trolley shaft, you will push the master link bar’s pins through the threaded shaft mounting hole that is placed at the end link of the chain. Then, push the master link cap over the master link bar pins. Finally, slide the clip-on spring over the master link cap until it is on the pin notches.

21

Reinstall The Inner Lock

To reinstall the inner lock, thread the inner nut up the trolley threaded shaft before reinstalling the inner lock washer.

22

Adjust The Tension Of The Chain And Cable

To do this, use channel lock pliers to apply tension to the chain and cable and reinstall the outer nut and lock washer. You will be able to hand-tighten the outer nut. Next, make adjustments to the outer nut to position the trolley threaded shaft so the chain hangs about ¼ inch above the base of the rail at its midpoint. Tighten the inner nut against the trolley to secure the adjustment.

23

Connect The Rail End And The Header Bracket

Use the clevis pin and the fastener ring to attach the rail end and header bracket.

24

Attach The Motor Unit To The Ceiling Bracket

Lift the motor unit up and prop it on the top of the ladder before finally lifting it all the way to the ceiling bracket and securing it tightly.

25

Activate The Wall Control And Safety Sensor

On your garage door opener unit, open the light cover to access the wall control and safety sensor terminals on the motor unit. Reconnect the wires to the motor unit and reactivate the wall control and safety sensor.

26

Attach The Straight Door Arm And The Outer Trolley

Using the clevis pin and fastener ring, reattach the door’s straight door arm and outer trolley.

27

Re-engage The Door’s Trolley

Make sure the garage door’s trolley is properly assembled and functioning.

28

Plug In The Garage Door Opener

Once you have completed all of these steps, you are ready to plug your garage door opener back into the outlet, or turn the breaker back on.

29

Check To Ensure That It Works Correctly

Now that the garage door opener is back on, you can test the door and your new chain. If the door doesn’t close completely, adjust the down travel and cycle the door open and closed. Continue to make adjustments until the garage door closes completely. If it doesn’t open completely, adjust the up travel the same way you adjust the door to close completely.

Conclusion

Replacing your garage door’s chain isn’t the easiest task and should be done carefully, but if you have the skills and tools available, there is no reason you cannot do this yourself. No matter what the issue is, whether the chain is just old or it has broken, it is nice to save a few dollars by repairing it yourself, but this is nothing compared to the feeling of independence and accomplishment when you are able to solely rely on yourself to take care of your home.

Commercial Garage Doors

When you are shopping for a garage door for your home or business, it can be tempting to limit your search to residential door options. However, if you use the garage as a workspace, a residential garage might not be suitable for your needs. Commercial garage doors tend to feature more robust construction, making them appropriate for high-use garages. Additionally, they are available in a broader selection of sizes, which may come in handy depending on your needs. Commercial garage doors don’t tend to offer the number of design options as you can find in residential front doors. Often, the aesthetics are secondary to function, so you may have a hard time finding choices that include certain features like architectural panel designs or decorative glass inserts. However, that doesn’t mean that attractive options aren’t available, so you don’t have to completely sacrifice design when you purchase commercial variants. read more
