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

Fixed my slipping garage door. Was very nervous we would need to purchase a new opener but this fixed the problem. Easy to install!

Easy to put on

Excellent quality would recommend Perfect replacement

Fit and works as it should

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.

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.

Worked perfect and reasonable price.

Works great

I didn't think this individual part would be available for Genie screw drives. Lo and behold it is. It seems to be of the same quality as the original. Just a tip, maybe your last one stripped because of lack of lubrication. I hadn't lubricated mine in years. The door sounded like a banshee when opening. Clean the threaded rod thoroughly when you put the new part on and apply high-quality white lithium grease in a strip from limit switch to limit switch on the screw rod. After I opened and closed it twice post-maintenance, the door sounded so quiet I couldn't believe it. I'm in Canada so I bought the extreme temperature lithium grease in a tube from Canadian Tire for about 12 bucks. Last part lasted 20 yrs with little lube. This one will be treated better.

Worked perfectly! Thank you!

When the garage door opener trolley failed I got this as a replacement. Seems fine so far.

This works great just turned out it was not the problem.

Everything was good and worked as intended. The quality is just like the OEM version. I'm giving it 4 stars because it was damaged on arrival. The seller should've put the item in a box and protected it with bubble wrap or foam. As you can see in the picture the item was inside a plastic bag that was placed in an amazon pouch. The corners of the unit broke during shipment. Luckily it didn't break on the corner that came into contact with the sensor so it's still usable.
