Genie 36179R.S Garage Door Opener Trolley Assembly Genuine Original Equipment Manufacturer (OEM) Part

worked great

Offered a much less expensive repair that corrected a door opener that was having issues lifting the door.It comes without installation instructions. I'm mechanical so the install was easy for me.

Works well

Bought this to repair the one that originally broke. I was hoping it would quite down the door when it in operation but it didn’t but that’s not the fault of the item it’s my garage door itself. It’s pretty to install, only headache was having to pull the track away from the wall but was easily able to install once the track was loose.

The item was a perfect replacement for a 25 year old Genie Garage door Opener and installed easily in a few minutes. However, the unit broke with the same failure that others have noted below, the plastic flanges holding the until to the track broke after a couple weeks of use. IMPORTANT – I found that the upper limit switch was broken/not functioning, causing the carriage to slam into the rail end stop every time it was opened. I have little doubt that this impact is what caused this as well as the original carriage to fail (the original stripped) I’ve since ordered the upper limit switch as well as a second carriage. I don’t expect any further failures. Make sure your upper limit switch is functioning prior to preplacement.

The part is original to the opener so of course it fits properly. My unit is 11 years old so I would expect some wear and tear. I probably should have paid more attention to maintenance, but who does. Good part, well priced.

Great quality part and exactly what was needed to fix my garage door issue!

My Genie garage door opener went FUBAR a few weeks ago, and it became clear that I needed to replace the trolley, as well as the shaft coupler and the limit switches for both up and down extremes of the door. The original equipment trolley part is a few dollars more expensive that the generic parts, but I would recommend the OEM part because it has metallic teeth engaging the door screw, rather than plastic teeth in the generic parts. It is very easy to replace by dropping the door to the closed position and unfastening the door end of the screw rail, which is a single nut. Disconnecting the upper end of the door linkage from the trolley, releasing the old trolley, and moving the loose end of the rail off to the side a bit allows you to slide the old trolly off the end of the rail and replace with the new trolly (with teeth in the "disengaged" position). Reconnecting the loose end of the rail, re-attaching the upper end of the door linkage, and re-engaging the new trolley, and you are done! If you have to replace the trolley, I would recommend also checking the limit switches for both maximum UP and maximinum DOWN, because you may find that it was failure of the limit switch(es) that precipitated the trolley failure. It would also be useful to check the shaft coupler, but that is most easily done by dropping the power head and rail to the garage floor. You probably do not need to do this, unless after replacing the trolley and checking the limit switches, you find that the door either does not move well or sounds pretty rough. Once the power head and rail are on the floor, it is very easy to replace the coupler.
