[AT] Super MTA Reservoir

Dick:

You can add an external two way hydraulic valve(s) anywhere between the pump
and the reservoir.  Just cut the pressure (3/4") line and the return (1")
line on the left side, put in Tee's and add the valve(s) - I did this on my
MTA just since the first of the year.

Re: the failed internal valve you didn't say what the failure mode is -
If it is failed closed - that is, you have no pressure on the output port on
the left side of the reservoir then no problem - you just don't have use of
the one way hydraulics.
If the valve is failed open then I guess you would have pressure all the
time on the output port on the left side with no way of shutting it off.
But the effect is the same - you just don't have use of the one way
hydraulics.
If the valve is leaking internally then the effect is probably still the
same (i.e., no good use of the one way hydraulics) with the addition that
the internal leaking would be acting like a "secondary" by-pass valve which
may be opening at way to low of a pressure thus rendering your' whole
hydraulics system useless.  This would be the only failure mode where I
would think you would have to open up the reservoir to get at the valve.

I have my reservoir off of the tractor at the moment (for painting) - so if
you decide you have to get at the reservoir valve I might be able to offer a
tip that will help

Good luck -

The hydraulic valve that is contained inside the factory reservoir on my M
is shot.

Can I pull the guts from the reservoir and use an external valve like I have
on my loader?  Or, do I need to put a new reservoir in as well?

TIA
