Ok. I understand. any progress with the Kubota dealer on that bigger hydraulic pump.

In my Kubota shop service manual it says that in order for the hydraulic pump to be in good condition, the discharge pressure should be between 13240 to 14690 kPa ( 1920 to 2130 psi ). I don't suppose these specs could be converted into gallon per minute?

The type of oil I have in my tractor is a Walmart brand called TDH (universal tractor fluid)

Sounds good. Thanks Wolfman.

One thing that I noticed about this unit. You can tell it has barely been used. There is no wear at all on the bucket teeth and the bucket itself and no scratch on the boom and the whole unit has a nice black glossy finish but all the hydraulic cylinders have a rusty faded color as though the...

I should just hook it up to the tractor and see what it does and go from there.

I agree. It would be nice to know the GPM.

No worries my friend. I appreciate your help and devotion. Don't despair. No one is perfect and there was no harm done. The specs for the original gear pump ( CBN-E310 ) indicates Pressure is ( low 16 to high 20 MPa) and the Nominal Flow is 10 mL/r and Input Power at 6.58 kW, Max speed 2500...

I just cancelled the gear pump order. I don't know if I need it. The part manuel for this hoe indicates that it has a gear pump. Sorry about this info. I just checked the backhoe in my shop and I guess the previous owner kept the gear pump and the oil reservoir. He mentioned he was going to...

The backhoe is a Jinma JW-03. Recommended for 18-25HP tractor. Can't find anything about the hydraulic requirements on this but I'm still looking. It has a gear pump ( part # CBN-E310 ). There is allot of data on this part number when I look it up online. I don't understand the data but it is...

Thank you. I just ordered the PTO pump, a 5 gallon oil reservoir and an oil strainer for the suction port.

Thank you North Idaho Wolfman. I have a choice through Princess Auto 7.2 GPM 540 RPM PTO Pump for $500 Canadian or 20.7 GPM 540 RPM PTO Pump for $600 Canadian. I am leaning towards the more expensive one.

Sorry wolfman. I didn't realize I was answering to you. You are the one that helped me in plumbing the back remote onto my tractor. Thank you for that. I was able to do a good job there. You might be right about the PTO shaft size. I attached a female shaft to it and it fit even though when I...

-I measured the PTO shaft size on my L285 to 1 and 1/8 in. . The newer tractors are 1 and 3/8 in. On eBay people are selling adapters for PTO that goes from 1 & 1/8 to 1 & 3/8 - I installed a 2 lever spool valve as a rear hydraulic remote and the way I tapped into the system is By following a...

This is really good info. I did think about the PTO pump but my PTO shaft is smaller( I know that I can get an adapter) and the RPMs on the tractor's PTO is faster than the max on the PTO pump ( I could probably run the tractor engine at a slower speed ). All that said, I did not know that I can...

I have a Kubota L285. I have plumbed into the hydraulic system to install rear hydraulic couplers. My question is , would this tractor have enough hydraulic power to supply the operation of a small backhoe attachment? All comments and advice are welcome.

I have this project completed and I think it turned out pretty good. I am including pictures of it. Thanks for all the help.

Good morning. Today I am showing off the result of the facelift I did this past week on an old 3 point hitch blade I bought recently. It used to be red but had faded into a pink color so I decided to paint it black. I took it appart and sanded it down best I could before painting it. I then...

Thank you very much.

Thank you Wolfman. I took the plate off of my tractor and I will get one made. Do you think a valve with this description would work. Function 4-Position, 4-Way Type Two Spool-Float/Standard Max. Continuous Pressure 3,750 PSI Max. Continuous Flow 9 GPM Relief Valve Setting...
