Moen manufactures multiple different handle mechanisms with a threaded dome. The assembly process is different for each of them. This article will identify the differences and explain the assembly process.

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: 3/32" Hex Wrench

Now that you have the handle disassembled, you are ready to identify your Handle Mechanism. The easiest way to identify your handle mechanism is based on the interior parts that you just removed. See the descriptions below for assistance. 

Identifier:

• Handle Type 1: The inside of the Handle Hub (D) will be hollow with internal threads (Fig 1).  For instructions to reassemble your handle click here 
• Handle Type 2:  Unlike Handle Type 1, Handle Type 2 includes an additional piece inside the Handle Hub (D) (Fig 2). This piece is identified as the Bearing Ring (H) and will be either black or grey non-metallic piece. For instructions to reassemble your handle

1. Insert the Handle Hub (D) into the threaded end of the faucet body and rotate approximately a 1/4 turn clock-wise to lock into place.
2. Slide the Handle (C) onto the stem of the Cartridge (F).
3. Using a 3/32" Hex wrench, tighten the Handle Set Screw (B). Confirm the handle functions by rotating it in four directions. On/Off/Hot/Cold
4. If the Handle Plug/Cap Button (A) is included with your model, insert it into the set screw hole in the bottom of your handle and push into place.
5. Turn your water supply on, confirm that the flow is working properly. You are done!
