No, I'm the proud owner of a Pfister Ashfeild GT26- It's listed as 974- on 4YP and 974- on the parts explosion. 074, but the one I got was a lot smaller than it should have been.
974-Pfister is a cartridge made by Pfister. 0740 is compatible with the Pfister F-Series faucet. 529- 7PDS.
The Limited Edition is a newer version with a rubber boot.

This was exactly what I needed for my Ashfield line, model 5297YP, kitchen faucet, which is about ten years old. The cartridge's part number is 974, according to the parts breakdown. 074, and this is unquestionably the correct replacement (despite the addition of a 0 at the end of the new part). It's also worth noting that the color has changed from all-white to black with a white bottom (as seen). The problem I was having was that the faucet handle would occasionally slowly drop down and turn on the water (at least a trickle). So I needed a new cartridge to fix the problem with the "loose" handle. The old cartridge is on the left, and the new one is on the right, as shown in the photo. br>br>It was very simple to change this. To begin, turn off the water. Finding the right size allen wrench (hex wrench) to remove the handle is the most difficult part, but it's relatively simple (just put the wrench in the small hole on the handle and unscrew the screw that connects the handle to the cartridge end). After removing the handle, I unscrewed a cosmetic cap (upper left round part in photo) by hand, revealing the locking device (brass, shown on far right). That is removed with a large pair of pliers (grasp it "head on" on the two flat surfaces with pliers or vice grips and unscrew it). After unscrewing the locking device, simply remove the old cartridge and replace it with the new. I did have to use a screwdriver to remove the old seal (which is now a light blue on the new part but was red on the original part; see photo bottom left for the old red gasket that I had to gently scrape out of the internal workings of the faucet). Assembly is the inverse of disassembly - Replace the cartridge (it has two nipples that force proper alignment), tighten the brass locking mechanism (not too tight or the cartridge will be damaged), replace the outer cosmetic piece by hand, replace the handle, tighten the screw that holds the handle to the cartridge with the hex wrench, and you're done! br>br>In conclusion, I am ecstatic! Thank you for taking the time to read:.
The unit is identical to the original. The only difference is the color of the plastic.
Note: The screw stud to which the handle is attached is not included - By unscrewing the original, you can get rid of it. replace the old one with a new one and screw it in place. The handle didn't fit perfectly on the new cartridge; I had to push it in a little, which was probably due to the new one being microscopically larger; however, this is standard practice when manufacturing plastic parts! br>Make certain that ALL debris is removed. Before installing the new one, any dirt that has accumulated in the brass port is cleaned out. If anything is present, the silicone gasket will be torn or worn out. leaks more quickly br>I recommend applying a thin layer of petroleum jelly to the silicone seal on the bottom before installing it to ensure that it moves smoothly and seals properly. br>Ensure that the nut holding the cartridge in place is securely fastened, but not overly so. Before installing the trim nut, run a test with the water on to see if there are any leaks or seepage. get a grip on it Mine leaked a little, so I had to disassemble it and tighten it up again. br>FYI, very fine debris screens are located "inside" the "ends" of the water hoses where they connect to the faucet pipes below. br>Because I was unaware of this, I assumed the cartridge had become clogged or damaged as a result of debris from the replacement of my water heater. br>In fact, the screens are extremely clogged. The supply hoses from the faucet under the sink had to be disconnected in order to remove them. Then, using a small screwdriver, I gently yanked on the sides of the screens, one at a time, until they came out - to avoid excessive bending I couldn't have put them back in if I had bent them too far because they fit so tightly. are shaped perfectly. After cleaning them, I pushed them back into place with a new pencil, eraser end first. br>With replacement screens, I wouldn't be concerned about the removal as much. br>Now I'm in possession of an extra cartridge. understand everything there is to know about repairing a faucet! LOL!.
I'm a big do-it-yourselfer, but this is the first time I've ever replaced a cartridge in a kitchen sink. I'm embarrassed to admit my errors, but I hope this will be of assistance to someone. What you should not do. br>br>
1. Turn off the water supply for both hot and cold. To clear the lines, turn on the faucet and double-check that the water is truly turned off.
2. Remove the handle by loosening the set screw. (The set screw does not need to be removed. )br>3. Remove the silver dome from the picture.
4. Remove the retaining ring that is made of brass.
5. Remove the old cartridge from the computer.
6. It's halfway full of water where the old cartridge was. The cartridge will be pushed down by the brass ring. Replace the old cartridge, replace the retaining rings, attach the handle, and run a water test. Pat oneself on the back for doing a great job. Water should be turned off. Wait 5 seconds before continuing. Water sprays everywhere from the faucet handle, creating a mess on top of the faucet and in the cabinet beneath it. Is there a problem with this component? After all, it's made of plastic! So, what went wrong? Here's where I went wrong. br>br>Ok, this is where I went wrong.
- After removing your old cartridge, use paper towels or something else to soak up any remaining water in the hole.
- Next, make sure your old cartridge's gasket did not stick to the faucet body, as mine did. Remove the old gasket from the area where the new cartridge will be installed at the bottom. My previous gasket was not blue, but rather clear.
- The following step will be taken. I'm debating whether or not I should install this while the gasket is still wet. Pfister is contacted, and he advises using plumber's putty. No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no I'm in possession of a napa silo. Hmm, glyde in the garage. Ah! I have a tiny container of oatey silicone grease on my desk. I'm not sure if it's necessary, but I don't see how it could harm the gasket or myself. I used some of it on the gasket and the mating surface, which I wouldn't normally do, but that silicone stuff was like water, nothing like napa sil- glyde.
- While lubricating the cartridge gasket, keep an eye out for the two plastic alignment pins and where they belong in the faucet body. Install the cartridge and wiggle it right and left until the pins are locked into place. Install the brass ring, the silver ring, the handle, and test it. br>br>By the way, one of the things I'm supposed to rate with stars is "stretch," which I have no idea what it is. Because I have no idea what zero stars means, I gave it to you.
