Adding auxiliary hydraulics to a 310C backhoe for a Okada hammer, please help

[Jaco1979]

Thanks for the input Scotty! I'll check back in here when I get the manual with some schematics.

The biggest pressing question is where and what (DCV) valve to buy- but I'm probably putting the carriage before the horse and need to be patient.

I have the rebuild of the hammer almost finished, waiting on seals from Hercules.

Okay so I bought a solenoid diverter valve that I can plumb into the machine. It states that it is capable of 26.4 GPM, The Deere manual says the tractor is capable of 26 GPM. The hose size that goes to the rear boom hydraulics is at least a /-16 size, 1" steel tube size. The valve I bought uses a D05 footprint and has 3/4 NPT inlet sizes. There is no flowrate for the D05 mounting plate, anyone know what I'm supposed to do here?? I mean I do need full flow from the tractor but it seems like this is a bottleneck in the system as nothing else is that small...

Thanks in advance...

That shaft in the pics looks pretty rough.

You might have better luck finding knowledgeable help on the Heavy Equipment Forum but some of those guys are members here as well.

When using the hammer it is better to have an aux. circuit with its own spool valve. I would not divert the boom hydraulics for this function. It may make it difficult to get the point unstuck.

The piston/shaft is not chrome plated on these so those are before and after pics, I've TIG welded some repairs with silicon bronze and machined it back to smooth.

Thanks for the advice, I'll try over there.

It's a open system so you have to divert oil from the loop to create pressure. It only diverts while 12V is energizing the solenoid to the diverter valve though...

Doesn't a 310C have two pumps? My 110 has two or three pumps. If you are tapping in to an existing circuit I would use the bucket circuit.

having just purchased a 310c i to am looking how to get some auxiliary hydraulics on it for a thumb/tree shear/grabber type attachment. i have an electric foot switch and hydraulic quick disconnects on the boom but nothing seems to do anything, there is a valve type thing under the machine that has a sylinoid on it that clicks when i activate the electric foot switch but can not seem to get any hydraulic flow or pressure from the fittings. thanks for any response/help

I’ve got a 310j that I intend on putting a thumb on. I’d planned on using a 12 volt diverter commonly used for grapples on tractors except I was going to use the flow from one the stabilizers so I have full control of the boom and thumb at the same time.
