Great job. Very well done. I wish more instructional videos were made this well. Thanks.
Very useful vid! Sure it’s a couple of years old, but completely relevant for a lot of people for years to come. This is also the same part for my Craftsman opener. Super easy fix for a part which is honestly designed to fail. It took 20 years, so here’s to another 20 I guess!
Happy to help!
Thank you..
Wow, this is the best excellent video where you really simplified the replacement steps for this garage door carriage assembly! Excellent job and thanks a million for sharing! God Bless!
Exactly what I needed. Thanks for making this!
DAM!!!;YOU JUSY SAVE ME A A COUPLE HUNDRED BUCKS!!!! THANKS FOR THE GOOD VIDEO TIP!!!!!
Excellent video…thanks a lot!
If the carriage is not damaged, all you need to replace is the wear pads inside of the carriage. They are about $6 for a kit at Chamberlain.com
Very use ful video. Nowever, my quesiton is why the idle pully deeps breaking. Is there is an adjustment need to made somewhere along with the chain. your response would be much appreciative.
The end of the track there’s a tab that you need to pull up which prevents the carriage from running into it. Also you don’t want to overtighten the chain
Thank you so much I just replaced this easily. My only question is should I apply any grease around the trolley carrier? It sounds and runs so much better. Great video.
You can if you want to but it’s got the plastic runners inside the carriage that help as well (:
Thank you for your video. I just replaced the trolly/carriage assembly and I'm certain it went back together properly. However, when I garage door opens it only opens halfway. When I try to close it, it reaches the bottom and reopens and stops halfway. I have tried turning the force adjustment screw but doesn't do anything. Any ideas how to remedy? Greatly appreciated.
Must’ve been put in the wrong place, take the chain off, press the button and step in front of the sensors. By doing this the motor will reverse and go to the fully open position. At this point you bring the trolley to about the fully open position and re attach the chain.
From there you would just need to make minor adjustments with the limits. I know it’s a bit. More involved but this should fix your issue
@@GarageDoorGuidance Thank you so much for that last instruction. Worked like a charm!!!
Tab is still hammered in.
?
Great video! For the tab that you hammered down flat, should you pry it back up? Assume it's just a safety tab to prevent the carriage/trolley from hitting the wheel? This vid was useful for me as the top wear pad closest to the opener side on my GDO is worn completely away (very heavy large door) so it's opening very slowly now due to metal on metal. The other 3 wear pads look fine so will have to follow your video to replace that one wear pad...assuming I can find them somewhere (I'm in Canada).
Yes as it’s a stopper to prevent the trolley from slamming into the plastic idler pulley 👍🏻
where in your video will I find how the purchase the trolley and carriage for a Liftmaster garage door? I'm a subscriber.
It should be in the descriptions in each video, is this exact one the one you need ?
Great vid thanks! How do you evaluate the tension that should be on the chain. I have a very heavy door.
You want it to be tight enough that it doesn’t have a big sag in it ( small sag is ok ) if I had to equate it to something I’d say a slightly loose bicycle chain.
I have Chamberlain whisper drive door opener. The carriage Assembly is stuck the other end away from door and it is not moving. Now I have to manually close the door. Is this a same process that you just did to release the carriage? Your reply will be appreciated. thanks
Love the video. I'm not sure this is my issue though. I disconnected the door and cycled the opener and it works fine. With the weight of the single wooden door, the trolley gets out to about 2/3 (the last joint in the rail) closed and it looks like it's hitting something and trying to derail. The carriage bolts are in perfect condition and tight in the rail and nothing else has changed. I can't see anything with an impact mark on it. It just started with a small noise and now it's a big noise. Does this sound like the reason the trolley/carriage has to be replaced?
There’s a portion of the opening on those wood doors that does more damage than the rest of the ride because of the way it opens. It could definitely cause the trolley to strip out and need to be replaced
Sounds like I need to replace the trolley and consider some new, lighter doors. Thanks for the video and lending your expertise!
@@GarageDoorGuidance So, the part arrived and I spent about an hour on the job. All done and it works just like before. Since I had the ladder and tools out, I watched the whole thing from every angle with a flashlight on every moving part. It turns out that the bolt holding the pulley (axle?) on the tension spring cable was loose which allowed the pulley to ride up the framework then pop out. Ten seconds with two wrenches and the problem was solved. Let's just call this a $40 lesson in observation and inspection. LOL! The video still helped. I approached the job with confidence and the only painful part was the blow to my ego. Thanks again!
Is the carriage assembly replacement the same process on the belt driven opener? The clip on the side of the carriage assembly where you thread the bolt thru which is attached to the belt snapped off the carriage. Can you confirm the carriage replacement part is sold as one unit with the trolley assembly? I have an 10 year old opener - Chamberlain Whisper Drive Model WD962KD. Thanks
It is sold as one unit and yes it would be the same with minor differences in the trolley
question, before unplugging it, can I put the opener in closed position first? Second Can i use zip ties (Tie Wraps) to hold the chain in position at the gear end?
You can do both yes
Is it worth cutting the wires for the garage door opener and just splicing them together after you reassemble?
Which wire are you talking about exactly?
@@GarageDoorGuidance. I thought I was going to need to pull the opener down to do all of that. Thers wires for ghe paddle to open and close the door that are run through the rail. I figured it out a hot minute after I asked the question... thanks!
Hi, You mentioned that you'd leave the part number somewhere but I don't see it. Also tried looking at Home depot online and could not find it. Any chance you can point me to it?
Never mind. I found it. Sorry to bother you.
need to see what kind of tolerances, with the nylon glides in place that the carriage should have?????
What do you mean by tolerances ? How much space between them ? Or how heavy a load they’re equipped to handle ?
@@GarageDoorGuidance I am trying to figure out when the door glides are worn out. should there be no space between the glide and the rail? should there be .0006 inch space? what would be considered worn out and time to replace? when replacing the worm and gear shaft I found one of the glides missing so I replaced it. the other 3 looked worn but serviceable so didn't replace them. unit is of course quieter now with the single new glide.
Where can I order the trolley and carrier parts?
Amazons got some, but Google works too

when the garage door opens, somehow the chain goes on top of the trolley and grinds. making grinding noise. how can i fix it?
Are you able to send me a picture or video? Garagedoorguidance@yahoo.
Is the carriage changeable
Yes
I had to do a manual release on ours the other day after the power was out due to a storm. when I came back later to reattach it, the carriage was completely stuck above the spring . its touching the part with the bolts beneath the pulley. any idea how to get that lose so it can go inside the trolley? thanx!
Jeff Wald which part with bolts exactly ? is the plastic pulley broken?
@@GarageDoorGuidance hey brother, I just completely loosened the chain and once I took it off the pulley on the motor, that loosened it on the other side which allowed the carriage to slide again. Boom!! Back in business. thanx!!
