Hydraulic Control Valve Group, Restoration of the 1855 continues

Restoration continues on the 1855. This video is resealing the valve body that oil goes into after the hydraulic pump. There are 4 valves combined into this unit, the relief valve that protects the system from overload. The priority valve, which makes sure steering and brakes have pressure before everything else. The pressure reducing valve that creates a separate flow of oil at around 180 psi to feed the brakes and pto. And of course, the unloader valve that prevents pressure from building until the tractor starts, making for faster cranking speed and easier starting.
I didn't find anything obviously wrong with it, so this was an opportunity to put new seals in it before the paint starts flying.
