Question about Kubota Third Function Valve Operation

[TripleR]

She must have worked for a different gummit.

I always have to laugh, well sort of a cross between that and cringe when I hear people talking about the highly paid government workers. I don't doubt they exist, I've just never met one and one sure doesn't live with me.

Thanks again to everyone who offered constructive advice, it has been helpful. I'm pretty sure it is the relief valve I'm hearing when the flow is overly restricted. That is why I opened the flow up some more. I'm trying to balance the valve operation while providing enough flow to keep the system happy.

As I said in a previous post I'm sure it has a lot to do with the fact that my grapple/thumb only uses a single 2" cylinder. When I built it I did not want to make the hydraulics so powerful that it caused other parts to break so I stuck with a single 2" piston. It has always been powerful enough to do what I want, but I may try a 3" cylinder to see if it slows things down a bit.

I still have the fall back of using the rear remotes which work great.

You don't want to pop your relief valve much, but a little bit won't cause issues. Popping the relied valve will heat up the oil & put a maximum load on the pump. But a 5-10 seconds of relief every 5-10 minutes or so won't be significant compared to normal hydraulic system operational heat generation.

I have restrictors on my TnT & hear relief kicking in when operating them. No issues here. I know FitRite sells a lot of em & I haven't heard any complaints or issues. Other than a few people drilling theirs out a hair wanting slightly faster operation.

Hi EZ

I had been looking fir a solid low hour 3240 cab for about a year before I said To myself, is that what I really want?

I kind this was a couple of years ago, but I wanted to know how you made out, and of you are still using the 3rd function with a grapple?
