I am encountering an issue where the main screw attaching everything to the cylinder will not come out (Beginning at 2:25 in your video). I have tried everything and it just spins but does not dislodge from whatever it is connected to.......what are my options in this case as getting this screw out kinda affects everything??

[tedjar]

@DirtyPandaDC Either the top of the cartridge it screws into is stripped, or the keyway it goes into on the handle is mangled. I have no idea how that would be possible though. Try lifting the handle while unscrewing it, I think it's just stripped and that might help it start coming out. Otherwise, drill it out. The threads it goes into are part of the cartridge so don't worry about messing them up.

@tedjar The pivot mechanism of the handle has broken and can see what happens with the turning of the screw....and the entire cartridge is spinning. There is no leakage...so is this normal?? I can open the faucet but to stop the water I need to push down on the top of the handle.

In order to repair I need to remove the screw but have no way to brace the cartridge for resistance to remove the screw. Should I try pulling the whole cartridge out with the handle or just get a new faucet?

[tedjar]

@DirtyPandaDC THe handle should not allow the cartridge to spin independently. Since you need a new handle anyway, just cut/mangle/destroy it and get it off. Then you should be able to replace the cartridge. Check with Moen directly for replacement parts if you can't get them locally. Otherwise just replace the faucet, especially if the rest is not in good condition.

I am having trouble with the disassembly. All is fine until I get to the step at about 3:00 in the video, when you "loosen the locking nut". When I turn the locking nut more than one rotation, it acts as though it is held in place with rubber -- it twists itself back into its former place. I turn, it turns itself back. The more I turn, the more forcefully it snaps back. I'm thinking that perhaps an old O-ring is adhered to it underneath or something. Help!

[tedjar]

@levarfan Are you sure the entire center section of the faucet hasn't come loose from the base and you are twisting the entire center section of the faucet with the hoses and whatnot under the sink? I don't see what else would make it act that way....

thanks to this vid i knew exactly what to do, how to do it and what to expect. 30 minutes ago leak..now, no leak. Thanks!

Leaking and stiff movement in the cartridge and faucet arm - first thought, call the plumber; second thought, MAYBE I can do this myself - (never worked on a single lever before).

Found your video - bottom line, successful repair and wifey is happy.. Thanks for your help.

Thanks to your video I was able to repair the dripping kitchen faucet today. Your the man!

I'm sure you've gotten many responses like this (I haven't read the posts), but THANK YOU SOOOO MUCH!!! I'm good at taking things apart (and usually at putting them back together), but my locking nut was so badly frozen in place that I had become convinced that it was an integral part, and I would have to remove the faucet from the sink in order to get at the cartridge. Your video showed me the way, and now the faucet is not only not leaking, but works far better than it has for many years!
