Hydraulics - guru needed - for 300U

Anonymous-0 · Nov 4, 2013

Hi all, I have once again developed a problem with my hydraulic system on my 300 U. It makes a horrendous screeching/growling noise, bogs down the engine, and then squirts me in the face with hydro fluid as it has AGAIN ruptured the rigid mount to hydraulic res. under the seat. I went through this last years and as per advice here, took it all apart, cleaned it all, flushed, installed new o rings and new fluid. And, installed a "new" rigid pipe robbed from a parts machine.
This machine has the regulator box in the rear and 1 valve ONLY.
I took the extras off last year.
I would appreciate somebody leading me by the nose through the fixing, cleaning etc.
I have the manual with good pics.
thanks in advance

I f you took off the regulator/pilot/control valve with the front valved you have found the issue. The system is not open centered. it is pilot controlled on demand pressure. Look to see if the valves removed contained the pilot and screen if so that is the issue. Jim
