Please make sure you don't have broken springs first and that the door is balanced properly. If so you can replace the "Trolly" by disconnecting the arm from the opener, undoing the opener from the bracket that mounts it to the wall. This usually takes a 1/2 in wrench. Then swing the opener out far enough to slide the trolly off and replace it with a new one. Re-connect everything then re-engage the trolly.

THE OLD STANLEY UNITS ARE NOT WORTH FIXING.

You may look at the safety sensors. Try holding the wall button down. If the door operates with the button held down then it is the sensors. Try to align them to look at each other. If not you are probably looking at either replacing the sensors or the logic board. Thanks BB

I NEED THE MANUAL FOR MY STANLEY 8500.51 GARAGE DOOR IT WON'T CLOSE


Try searching around here to find similar or hopefully exact opener. Stanley no longer is in the garage door business, and the company that bought them out went bankrupt.
Good Luck

How do I put my chain back on a Stanley 8500 Garage door opener?


First you must make sure the sprocket on the garage door opener is spinning clockwise and reaches its limit and stops, you can easily put a pair of pliers between the #1 and #2 terminals on the garage door opener and start the sprocket spinning or just grab a remote and watch from the back of the unit (looking towards garage door ) and make sure it,s direction is clockwise, Once it stops you wanna loosen the chain enough so you can position the carriage which is connected to the chain and with your door closed send the carriage down far enough so that the carriage and the trolley both engage then all you have to do is put the chain over the sprocket and tighten up the tensioner that is located on the trolley...not to tight and not to loose is what you would want in an adjustment !....now since you already ran the sprocket in the down position your door is now ready to test ...when you press your remote or wall station the door will travel up, You have to do it this way , if you don,t ..you can damage the machine or your door ! Good luck and hope I was able to help you with your dilemma!

If you are talking about a garage door opener then you should disengage the safety lever so the door will go-up and down with little effort if it doesn't then you need to adjust the door untill it does. Hope this helps

STANLEY GARAGE DOOR OPENER mODEL#9105 OPENS WHEN NOTHING IS UNDER


Stanley has been out of the garage door opener business for over 15 years. I reccommend replacing these openers when they start acting up because it is so difficult to get any parts. There is a reason that they went out of business.
