That's a sound and positive fix.
- - However it requires changing the dump valve, running a return line and
pump modification (replace the reservoir).
- - - - Later models of the OilDyne pump have a port between the two
pressure ports that dumps directly to the reservoir.
- - - - - - no reservoir changing needed.
- - and the pilot has to recognize the problem and intervene.
Obviously, I prefer a fix that does not require pilot
intervention - - fully automatic.

I have been following this thread and have
complained about many of the same issues.
I have the 235 set up with the
oildyne pump from 1987 . I removed the original dump valve and replaced it with
a Swageloc valve that has another port on it. I ran a poly line (no pressure)
back to the resevoir. I had the round metal resevoir and replaced it with a
plastic one that I purchased from Oildyne for about $45. I put a fitting into
the to of the plastic tank and the return line goes there. When my dump valve is
opened in addition to connecting the high and low sides together (still
pressurized but equal) mine dumps pressure back to the resevoir taking pressure
to 0.
No more carrying a 9/16 wrench to crack a fitting so I can raise the
gear.
The valve was about $60 if I recall.
This does not solve the
problem of the system building pressure when ambient temps go from cool to warm,
but it is a cheap solution that has worked for me...
