How do I install a kitchen faucet loop clip on a Moen single faucet handle? Part number 0-3067.

SOURCE: Repair cartridge in Moen Monticello single handle lavatory faucet

After some additional experimenting, contrary to information I was previously able to gather, I discovered that the white plastic retainer doesn't (in this type of Moen faucet) actually screw off but rather is held in place by a spring clip inserted from the rear of the retainer (toward the wall side of the basing). Simply sticking a small screwdriver in the opening (approx. 45 degrees downward) and tipping the screwdriver toward the front of the faucet, snaps the spring clip out through the opening.
The plastic retainer than lifts off. Note: the flat sides on the retainer suggest that a wrench will be needed but such is not the case.

Finding brand specific replacement parts in stock for a 20+ yo faucet without a Mod.# is quite the task, implying that you would have to do a side by side compareson/inspection. If in fact that part is not obsolete.
Maybe you should consider replacing the entire faucet.
Good luck

The top pops off and there is a crew under it. It's all pretty easy but when you put it back together you have to do a tricky angle kick with the handle. Watch carefully as you take the handle off and put it on and off several times to see what is needed. If you do it wrong the handle sets on top of the black thing and doesn't work right, The cartridge in the faucet pulls out with difficulty if you have hard water. There is a little clip near the the top that holds the cartridge in. You should be able to get a repair kit that has the cartridge and new O-rings for the spout.

Replace the "O" rings that are behind the spout portion. You will have to remove the top of the faucet and pull up on the spout section. There will be a couple of "O" rings there. It is best to have Moen send the parts to you as locating the proper size "O" rings can be difficult.
