FEL Build Questions.

That may work if you have clearance.

The new valve should have 3 ports. Pump, tank, and power beyond. Tank would be a third line that returns the low pressure oil to tank/reservoir. The tank port is typically only rated for a few hundred PSI, so if you try to feed another downstream valve (like your 3 point) from the tank port, you can damage the valve.

This is the design I'm basing it on.

Yikes! That's an ambitious goal. I figured you were talking about a trip bucket.

So this is what I found.

But your saying use the PB port and then have a return, got it. :thumbsup:

And the adapter just keeps me from cutting the steel line which I like.

You guys are all a wealth of information I really appreciate it.

Jaxs - Yea I need a full loader to dump into truck bed do some dirt digging etc. I know my tractor is small but she be mighty :laughing:
While ambitious yes, aside from the Hydraulics I don't think it is beyond my capabilities. The tractor was designed with a FEL optional from factory so it wont be beyond its capabilities as well. I have already built several implements and parts for it that get hard use so this is the next eventual step.

There exists an adapter for aux hydraulic circuit that is factory made.
A member "Bill" has duplicated them and he is usually on this site.

Pricy per say but not really out of line considering.
It mounts left rear in the 3 point area.
(have the OEM on my CUT) and use it for my log splitter.
The other option is another hydraulic pump driven off of the crankshaft pulley (as I have done). Again there was a factory adapter to do this.
Advantage is that the factory pump is somewhat slow for FEL usage and I used a larger volume pump making my FEL a pleasure to use.

I love the idea of using a separate pump and hydraulic system for the loader then I don't have to worry about cutting into my current system and damaging my three-point or starving the transmission or anything. I saw a bit about a front PTO in the manual I didn't delve into it very much. Can you provide some more information Insight on that please?

So a few minutes with the calipers and my brother is going to make me the adapters that mount at the pump.

Started mock up got the cross bar put together.

Tomorrow I hope to finish the subframe.

A few years ago, I built a loader for a Kubota B7000 I had at the time.

I also went with the separate pump/reservoir solution. It allowed me to use a slightly bigger pump to make things go faster, while also not messing with the tractor's hydraulics as they're not designed to handle a loader.

I machined a pulley that would fit right after the main crank pulley, then just mounted the pump on the side of the engine and run a belt to it.

Well works sucked so slow progress. Here is in progress and completed subframe.



And my brother got the adapter done.

I drove my pump off of the crankshaft using the factory attachement.(they designed it to run blowers etc so the crank can take it)
Problem will be that the crank bolt pattern is a 3 bolt affair and to make it well centered will be the challenge.
In my case (10 yrs back) I was able to purchase the part so that was easy.
I also used an universal joint to couple the pump to the crankshaft output thus eliminating critical alignment issues.
I simply fabricated a 'spreader' across the FEL sub frame to mount my aux pump.
My FEL reacts like a spirited colt vs the slow factory device and low factory pump CFM's.
Hey, over 10 years and absolutely no issues.
I am aware of many other tractor brands that use the front aux pumps for secondary hydraulics.

Just be sure to use a U joint so as not to harm the crankshaft front seal.

I considered going that route with a front pump off the crank. The pump cost was close to 200 plus extras. I decided getting him to machine the adapters for nothing was worth trying. And while it isn't the oem device it functions the same. If it's not quick enough I'll definitely get the pump.
