Valve screeching

[Jay4200]

The fitting in question is just a swivel adapter.

Right, is sure looks like a simple swivel adapter, BUT there is no reason for it to be there - so what is it actually doing?. The PO had the hoses going to male QCs to plug directly into a set of remotes on the tractor. The hoses are built to thread right into the cylinder, as the other one does. Puzzling.

It could be that they put a restriction in that swivel. Only one way to find out. I have not limited travel on a valve like I suggested. What I envision, would involve a little welding. I would take a short piece of angle iron and mount it to the valve mounting bracket running parallel to the handle travel. to that angle I would weld nuts above and below the handle so it would not limit the travel. Then i would use a bolt and another nut on each welded on nut to provide an adjustable stop for the lever. Once you get it adjusted, lock the bolts with the jamb nut. You would need to space the nuts you weld on far enough from the angle iron (shimmed out 1/4" maybe) to allow the bolt and jamb nut room to turn. Is that clear as mud?

Interesting idea. That would be relatively easy, although it would've been a heck of a lot easier if I had thought of it before finishing off the mounting arm/table that is bolted to the blower 3pt mount - I made that along with all of the hose/QC mounting hardware that I (*gasp*) bolted to my ROPS. I will admit, I have terrific hindsight.

Probably just as easy/hard is my idea to redesign the chute mount/slides so that the chute edges run against bearings instead of being jammed into a plastic slot. I should be able to nestle std wheel bearings into the existing guides - a few precisely-drilled holes and bolts, and the chute should run almost friction-free, which I am reasonably convinced will eliminate any future overpressure issues.

Never seen a setup like that.

Turns out that my Econor hydro setup (they don't use it any more) is used by Pronovost blowers, which have a good rep on this forum. I guess both Pronovost and Econors are belched out of the same factory - looks like the same blower to me.

It looks like they changed the design, as did Econor, but in feature photo #1, the stupid hydro hoop is in the background.
