706 hydraulic leak.

[young tractor]

Hi guys my son is looking at a 706 diesel. It has a hydraulic leak on the back of the tractor it the left round barrel in the picture. I haven’t been around IH stuff much what is it called and can I get a new one? Is it very expensive to fix. I look forward to hearing your advice

Control valves
The link takes you to the parts diagram. There are multiple Orings and seals in the assembly. The rings and componente are mostly availlable at the sight link. Jim

Jim has it for you. The detent pin or as they calll it the piston is the most expensive and is probably your leak but while it ia aprt might just as well do both valves and the poppet then they would be good for many years. I need to go through the ones on My7 806 if you take the valves off the tractor get the 6 orings that go between the valves there are 3 for each valve and both are the same so 2 of each will seal them up going back on.
