Price Pfister diverter valve help

I am rebuilding a Crown Imperial (or is it Crown Jewel?) 3-handle tub faucet in a 1960's home. I replaced the hot and cold stems with 910-013 and they matched the originals. I replaced the diverter with 910-022 and water goes to both the shower and tub when the valve is set to shower.

When comparing the 910-022 with the original, the original is slightly longer. The difference in length is in the area marked in the pic.

I've seen post about using two sealing washers. I have not tried it with the 910-022 but the difference in length is about the thickness of a washer.

Can anyone identify the old diverter valve and hopefully provide a part number?

Also, what would it take to convert this to ceramic cartridges? Could I buy a 00131XA rough-in valve and swap over the stems, then buy a new trim kit? The valve body is behind a tile wall so I don't want to change the whole thing.

 

Your diverter stem is longer than normal. I checked old, new, and aftermarket 910-022 diverters and they are all like you're new one. Stacking
950-040 diverter washers will be your best option. I would use an adhesive to make these into a single part. If not you may have problems removing the diverter at a later time.
As for a ceramic disc cartridge the H/C are # 910-030. No ceramic diverters are available.

 

Thanks Marlinman! I ended up replacing the washer on the original diverter and re-installing. And thank you for confirming I have an oddball diverter. I spent hours on the internet trying to find a match with no success.

The weird thing is that I'm sure it's a Crown Imperial and the valve body must also be non-standard to accept the longer diverter. I can't believe Price Pfister made two versions of a valve body for the same model!

 

HJ, thanks for your insight! I may have the non-convertible Crown Imperial since it has the odd longer diverter stem. I'm sticking with compression stems for now and using the original diverter but I would like to switch to ceramic in the future if possible.

As an experiment, I gently closed the hot stem and removed it from the valve body. The distance from the mounting flange (not gasket) to the end of the compression washer is 1 1/16 inch (see pic). That should also be the distance from the flange to the face of the seat. I'm going to get a 910-030 and measure the equivalent distance.

I found a reference on the web to a special seat with a flat face used for conversions. It appears to be aftermarket and is advertised as "Pfister - Seat to convert to ceramic stems." Has anyone heard of these?
