Have a massey 50, rebuilt cylinder, but not control valve that sits on top of cylinder, where the two hoses connect, cant find any parts or a new one...now after complete restoration can't use tractor, leaks bad, dealers say parts are obsolete, have to get old stock somewhere or get used one, been a year now, this is a school project for our FFA program, ANYONE HAVE ANY SUGGESTIONS on how to get this parts fixed.
 
Have you taken it apart yet? What parts within the valve assembly can't you find? Some things like O-rings are available many places and the parts book gives dimensions.

Our local dealer couldn't find any sizes etc....they told me they can't get, I need the o rings, they had one seal for it, and the part where the o rings go on is a little pitted, but the o ri ts were shot and in pieces, hopefully the o rings will fix it, have any ideas, are there any other parts I am to thinking of
 
Just a thought but do you have a good plumbing store around they carry orings for plumbing pipes sinks and such and are good quality rubber might be worth a look.
 
Does this look like your control spool? This one is style on my 150.

IT manual stated to insert a pin punch into one of the hose ports to hold spool and unscrew linkage end. WRONG. I had to remove the seal (small chisel) and then there is a spiral snap ring behind the seal to hold the spring and spool. I had to use dental picks to remove the little bugger. The seal number is SKF 6741. On the other end is a dust cover, mine had drive rivets to hold cover. Just pry it off, it doesn't seal anything. There is an internal O-ring in the housing that the spool end seals within.

Hope this helps

I have a complete seal kit for M/F 50 steering cylinder and control. It contains 2 seals and about a dozen O-Rings. $59.80.
