Today I picked up a spare kitchen faucet from someone gutting a 1976 Revcon. My faucet has a problem where you can't turn the spout so I wanted something I could use for parts if needed. This also gave me the opportunity to figure out what is needed to recondition both the kitchen and bath faucets. Turns out it's pretty easy and the parts are readily available. First I looked online and then went to my local Lowe's big box store and they had everything needed. The basic thing to know is that the faucets are made by Valley and when looking for parts they are considered the "old style". It appears that they used the same design for a lot of years. I spent under $20 for all the parts to do both faucets. The following assumes you have the original faucets. Click on the pictures for larger views.
Here are the parts to redo the faucets. Both faucets use the same internal parts. There is a cartridge assembly and seats/springs.

They also had new handles for the bathroom faucet but I didn't need one. New handles are available online for the kitchen faucet.

Here is the faucet disassembled. There is an allen screw holding the handle on, use a 1/8" allen wrench to loosen it. On the kitchen faucet the screw is in the back of the handle, it's on the front of the bath handle. Once you remove the handle, unscrew the top. This can be done in the coach. No need to remove the faucet.

These are the seals in the bottom of the faucet. There is a spring and a bushing below them. This is what seals the faucet cartridge to the water supply. Pull these out and replace with the parts provided. Probably helps to put a little plumber's silicone grease around the outside of the seals so that they move in the bores smoothly.

This is the new cartridge installed. Note the direction of installation. The parts I bought came pre-greased.

After everything is assembled, screw on the cap and then attach the handle. Turn on the water and check for leaks and operation.
