Backhoe Need help with Bradco 6LD backhoe pump

Carrizokid · Jul 17, 2015

My hydraulic [PTO driven] pump bit the dust. I need help finding the proper replacement pump. I don't know what GPM is needed. It's mounted on a sub-frame on my Kubota B1550, it's pretty tight on space so it needs to have a circumference less than 14". Any assistance would be greatly appreciated.

If it is mounted on the subframe,.............does it hook up to your PTO? Any PTO hydraulic pump would do. Goggle your backhoe specs to find how many GPM it needs to run right. Then google PTO hydraulic pump and your needed GPM. This should get you in the ballpark.

"Bit the dust" is descriptive for sure, but doesn't convey if the pump might be rebuildable?? If there's brand and model number to look up, a repair kit might be cheaper than buying a new one - otherwise do as bindian suggests.

Rebuild kit definitely, if you can find one.

Thank you Brandi, I have a manual for the backhoe, but it's just a parts manual. So there's no information on the GPM requirements. I think that the pump that come with Bradco was not original. I'll have to clean it up, but it's beyond a rebuild. Gears have worn into the housing.

The pump's innards have worn into the housing. It's now scrape material.

Have you contacted Bradco? Someone at the manufacturer should be able to give you that kind of information about a prior product. They are a pretty good company from what I hear and it might take a phone call or two to find the right person but probably as reliable as it gets.

Grandad4, I was able to reach them just the other day and they emailed me the needed information. I just have to get back to them for a price. One place quoted a price around $1000 for the pump. After I regained consciousness, I started looking around. Still looking at this time. I need a pump that can produce 4 to 6 GPM at either 540rpm or 840 rpm. I think the previous owner might have Mickey Moused the setup. I'll get a few photos of the PTO area and post them, hopefully there's another B1550 out there to compare to. Mark

Bradco does "like" their stuff a lot.

Yeah, they do, but I also like their stuff a lot as well...my 511 has a 14gpm pto pump and runs the hoe nicely just above idle (around 1100 rpm). BobG in VA
