414 Inter Hydraulic Problem

[R W]

Have a 414 Inter tractor which is losing almost all hydraulic pressure due to
the fact that almost all the oil is being dumped though the Slow/Fast control
port much this is caused by the absence of a piston & spring which are almost unobtainable.
Any opinions on blocking the Slow/Fast port which appears to be a bleed
off arrangment as far as I can make out, this should be easy enough done.
Thank You.

How about a needle valve. It can be adjusted from zero flow to off.

 

[R W]

A good idea if it could be adapted.

Is this a master flow control valve? Rockshaft? SCV? Loader?

 

[R W]

Controls 3PH only.

Not finding any good info on 414 hydraulics. What became of the original piston and spring? Can you send pictures of the manifold/casting of your flow control?

 

[R W]

The original spring & piston were missing when the tractor was purchased, have obtained a S/H spring & piston from a wrecker will fit them tomorrow.
Sorry am unable to post pictures.
