I want to clean up this proportioning valve but before I open it up is there anything I should know... do's and don'ts; is anything going to launch across the shop to be lost forever? :Thud:
Any reassembly tips?
I referred to a factory diagram, there are springs in there ,just be careful in dis-assembly. But i could not dis -assembly fully. I believe a previous post covered this. I pulled mine off the car because it wasnt letting the fluid through. I luckily had another in storage from a parts car that works. Apparently they arent reproducing that model proprtining valve.
As your un-screw the caps the tension on the springs is released... Not a problem, have fun...
I've got an exploded view of that valve on my work computer. That will have to wait until Tuesday.
It's good that your lines are still attached. If they sit for awhile with no lines attached, they will rust up inside. Yours looks like it's in great shape. You can plug the ports and soak it in EvapoRust to clean up the outside. If the inside is rusted, you can soak it too.

With all the ports blocked off I glass beaded mine and then polished it with a soft wire brush on a bench grinder. Looks brand new! :bigthumb:
It looks like it does because I glass beaded it about 8 years ago and painted a clear coat on it which obviously did not hold up considering it has been in a box indoors since.
I will get some of that EvapoRust and start over. Exploded view would be welcome :bigthumb:

Here is the exploded view.
The bracket is riveted on.
Ok, I guess it stays then.
Thanks

My valve was sitting "open" for years. It was rusted up inside. I soaked it in EvapoRust which cleaned up the outside but the large valve assembly on the right side of the picture was rusted in. It came out in pieces. I soaked it again once that valve was out to clean up the inside. I was not able to get the brass valves out.(I think this was before I found the exploded view to see how it came apart) Since those were brass(and can't rust), I just left them in place. I found a replacement valve that I was able to use for parts...and replaced that valve assembly that was broken.
Kroil is pure MAGIC! I probably have a dozen cans in my shop.
I didn't have any problem getting the fittings out, but the large valve assembly was rusted in and I broke it trying to get it out. I didn't remove the brass valves because I didn't know how they came out. If you get those out, please share the process on how they are removed. I might take my valve back apart and completely disassemble it to make sure it's completely clean.
Maybe you just insert a small screw into the end of the brass valves to pull them out?
Got the big nut (only) off but had to use a different method than the C-clamp because the nut has a pin protruding through the center of it that extended beyond the outside edge of my box wrench.
Forgot I had a hand impact and it did the job with the valve in a vise. Again only the nut screwed out leaving the pin and valve still inside. Another overnight of Kroil and maybe it and the valve at the opposite end will give up up too. :dunno:
:wrenching:

I soaked the valve assembly with penetrating oil to try and free it up. Don't do that. It swelled the seal and it ripped. I'd soak the assembly in more EvapoRust now that the end fitting it off. :alan2cents:
Rut-row... damage probably done by now then. :( I was planning to get a kit for it anyway. Back to the Evapo-rust bath it goes then. :bigthumb:

Thanks. I have the replacement valve that I used for parts. I guess I can experiment with that one before tackling the original one. Sounds like it would be a good idea to completely disassemble the original since you found a lot of hidden sludge in yours. :bigthumb:
It makes sense. Thanks!
