Do the CA, WD and WD45 use the same hydraulic parts?
I have a CA and need (1) valve body for the hydraulic pump [has the lever attachment and the hose outlets], and (2) two hydraulic rams [about 14 1/4" long compressed]. I'm having trouble finding reasonably priced parts for the CA, and am thinking that if I could expand my parts search to include the WD and WD45 models, there should be a lot more hydraulic parts available for sale.

A lot of the B and C hydraulic components are supposed to be the same as the CA from what I have read. I do not see any similarities between my WD45 and CA hydraulics from the outside.

Dale, I 'think' the parts you are looking for are unique to the CA. The pump is similar to the WD/45 pump but not interchangeable. The rams are unique for sure.
I have some CA parts but quite a ways from you, Mike.
Edit; Google maps says about 600 miles.

you should be able to adapt WD or 45 cylinders ( or any) to the CA if you want... I wanted a larger cylinder for a B ( instead of 2 small ones) and i bought an old WD cylinder and acutally cut a few inches out of it/ welded, to make it shorter.

Like them all, but love the "B"s.

CA shares nothing with the B/C hydraulics. the Pump looks like A WD but sint the same WD Rams are several inches longer than CA ones but the same diameter.

I appreciate all the responses.
I have located some replacement CA hydraulic rams, but am still searching for a valve body.
The problem with my existing valve body is that the casting split on the nose end while running the PTO. It made a loud clanking noise, split open, then about a quart of hydraulic fluid came out. I assume that there was too much pressure after I removed the leaking hydraulic rams and hoses and capped the outlets on the valve body. I had the fluid reservoir on the 'full' marking so it probably was over filled with the rams and hoses removed.
I was wondering if someone could successfully weld the split on the valve body nose? I'm not a welder, so I'm not familiar with what can and cannot with welding cast iron. If you might happen to know, please let me know your thoughts.

Dale, it could possibly be repaired if you can't find a different one.
Paul Ohms has lots of CA parts for sale on yesterday's tractor. Here's a link to a pump; http://www.tractorshed.com/cgi-bin/photoads/classifieds.cgi?search_and_display_db_button=on&db_id=718978&query=retrieval" rel="nofollow - http://www.tractorshed.com/cgi-bin/photoads/classifieds.cgi?search_and_display_db_button=on&db_id=718978&query=retrieval
