BH hookup ?

ditzel · Feb 25, 2008

Need Hydraulic help, big time.
Just got a woods bh6000, don't have a pto pump/tank, so I need to tap into tractor hyd.
Tractor already has a FEL from factory with 3 hoses coming from hyd. block- 1 into P, 1 into PB and 1 into T.
I installed two tee's, one into the P port and one into the T port and ran the lines to the BH. Also the bh has a pressure diverter valve on it.
The BH only works (real slow) while I depress the FEL raise lever.
What did I do wrong and how do I fix it?
Thanks
Tom

It's not working because you CANNOT "Tee" pressure lines. All valves must be plumbed in series. Hydraulic fluid is like electricity, it will take the path of least resistance, and that is not your BH!

You need to take a line from the PB port on the loader valve to the BH INLET, then the BH OUTLET to where the PB line is connected now. Plump in QD's so you can remove the BH, and make sure the lines are connected back together when the BH is removed as this PB line has the full flow of the hydraulic pump going thru it, and series damage can occur if it has no where to go.

Clear as mud

Thanks for the info, now it makes sense. I looked at some other posts about PB but it didn't sink in. The information you can obtain from this site and the folks on it is awesome.
Thanks

Say Ditzel, when you get that bad boy set up and mounted be sure to post some action shots! BTW, where abouts in NJ are you?

I will post some action shots as soon as I get to try it out. There is a pic of it now on the attachments forum under "bh6000 on mahindra 2615". I'm in somerset county, nj.

OK,
BH works but not real fast when tractor is running about 2500rpms.
Is this normal?
I have the hose from FEL PB going to BH in, and the BH out going tee'ed into the tank port on the block with the FEL tank line, and I plugged the N port(where the FEL PB was going to).
At idle, the BH doesn't move.
This is the way Woods says to hook it up in the manual.
Any suggestions appreciated.

KennyD,
As per Woods tech support, I hooked the line from my PB on the FEL to the BH inlet, and the BH outlet tee'd into the tank return on the tractor hyd block on the frame rail, also plugged where the PB used to go on the tractor hyd block.
The BH now operates, but at probably only a 1/4 of the speed that it should.
And at idle or 2000 rpm doesn't really make a difference.

Would changing the BH outlet to where the PB used to go on tractor hyd block on the frame rail instead of the tank return tee make a diffence?

Sorry I missed your last post...

I don't think that hooking the return line up differently will make a difference, but I guess it's worth a try...
What is you hydraulic pump on the tractor rated for? (GPM)
What size hoses did you use?

tractor pump is 7.8gpm and I ran 3/8 lines. I'm baffled cause the FEL operates normally, even at idle. the BH has a diverter valve for use with tractors w/greater than 5gpm. i'm wondering if that might be cause my problem
