Our garage door opener's old inner trolly broke off a piece where one end of the belt attached. Had multiple garage door company look at it, everyone wants to replace the entire system because ours is over 20 year old. But this is really the first time that the opener part ever had any problem. The belt itself was even totally ok. So after some research, I ordered this trolley assembly according to the part no. on owner's manual. There is even an option for delivery slot of 4-8am the next morning, which I chose. It was delivered before I got up so once got up, I just got working. The most difficult part of the project was actually to unscrew the nuts to take off the rail off the wall bracket so the trolly can be changed! I did have to switch the screw on the existing belt so it will fit into the new inner trolly (the old one was just a bit too thick). The provided spring was perfect too as the old one got expanded when it fell off the old inner trolly. This repair totally works! We have a functional garage door opener for just spending $37.14!
