A guide to installing a 1234 cartridge in a two handle kitchen faucet that does not have a lower base plate.

Preparation:

The water supply shut off valves must be turned off- see article How to Turn Off the Water Supply to the Faucet.
Recommended Tools: Flathead Screwdriver, Needle-Nose Pliers and/or Removal Tool 14272 (You will notice two separate instructions listed below depending on the tool used).
The following instructions assume the handle and associated handle pieces have been removed. For additional details, visit solutions.moen.com and select the type you are repairing. The faucet guide will contain specific information on handle assemblies associated with that style of product.

Disassembly Using Needle-Nose Pliers:

Slightly push on the side on the stem extension (#1) that has five splines at the top (see Image 1). Use pliers to pull up and remove the stem extension (#1).
Insert needle nose pliers into the valve body (#4) so they are in the recesses in the cartridge nut (#2). Unthread the cartridge nut (#2). The cartridge nut (#2) will not unthread all the way out of the valve body (#4) so you will have to use the needle-nose pliers to pull the cartridge nut (#2) out.
Pull the cartridge (#3) out of the valve body (#4).

Disassembly Using Removal Tool 14272:

Use the removal tool 14272 to unthread the cartridge nut (#3). The cartridge nut (#2) will not unthread all the way out of the valve body (#4).
Using pliers, pull up on the stem extension (#1) which will also pull the cartridge (#3) and cartridge nut (#2) out.
To separate the stem extension (#1) from the cartridge (#3), slightly push on the side of the stem extension (#1) that has five splines at the top (see Image 1). Insert the end of a flathead screwdriver into this gap and gently twist the screwdriver to release the stem extension (#1) from the cartridge (#3).

Assembly:

Insert the new cartridge (#3) into the valve body (#4) aligning the tabs on both sides of the the cartridge (#3) with the recessed indentations on both sides of the valve body (#4)
Reinstall and tighten the cartridge nut (#2) using pliers or the removal tool (14272).
Snap the stem extension (#1) onto the cartridge (#3).
Rotate the stem extension (#1) to the "off" position (clockwise for hot, counter clockwise for cold) until it stops.
