JunKeBluB2 Hydro-Assit

[JunKeBluB2]

First I don't know if this will work the B2 is still on jack stands. Used stock B2 pump don't Know if I'll have enough flow for box & the cylinder but here it is. Got the cylinder (2" x 8"), hydraulic lines (pre-made), & fittings from Tractor Supply everything else I had on hand. Cost of build about $150. And if any of you have hydro-assist & can tell me how to bleed the system it would really help out. Thanks in advance!

First pulled the box



Box Dissembled



Box drilled now tapping



Holes taped (upper right & bottom center of pic)



Ready for assy.



Box assembled hoses attached



DRilling out flow valve



Everything back in



Blocks welded to axle & tie rod. Cylinder in & lines attached





This is my filler neck extension for xtra fluid capacity used 2" x 1 1/2" reducing coupling turned 1 1/2" side to about .010 press fit into pump filler neck turned 2" side to clear air cond. lines used 6" of 2" pipe w/ threaded adapter & screw in plug w/ vent hole drilled in center









Now as I said don't know if it will work or not but to give credit where I got build info check out this link.

very nice Ronnie!!! When I get my junk done, we will have to go to Gulches to test out each rig!!!!Chuck

[JunKeBluB2]

[krazybronco]

you are building one sick b2 man so glad i got to wheel with you

[JunKeBluB2]

just to let you know the hydro works great after i got it bled little slow at low rpm may drill out valve more. pump doesn't whine or steering doesn't lock up at half turn like it did.

[krazybronco]

sweet when i get 35s your building me a doubler and hydro assist you just dont know it yet

[blazinchuck]

Ronnie, I think you should get up with Matt and do some write-ups for BIIs in broncodriver mag :wink: .Really,Chuck

[krazybronco]

Ronnie, nice work, I love to see machine shop creativity at work. 8)
Realy, nice work. When I was at ford they had special bleeding procedures when replacing Ps pumps. In your case I think it fits.
With the truck on stands, fill the fluid res, turn the wheels lock to lock repetitvly. With out running the truck. If there is air in the system you can score the pump by starting it up too soon.
One of the big trucks(monster truck) I worked on had hydro steering and from time to time would bust a line. It was often necicary to crack a line too bleed the air out of it. Just watch the tefflon tape as it can leak afterwards.
The Ps pump in the BII isnt the best, I would try to switch to a GM pump from a C20(see my BD artical or Classicbronco tech articals) or an aftermarket pump. They also switch to ATF insted of PS fluid. This seems to work better at higher psi with less seal failure.
You also may want some more gussets on the tie rod where the piston is welded too. Lots of stress there.
Cant wait too see it in action.

THANKS FOR THE KIND WORDS GUYS BUT I'M NO TECH WRITER JUST DO WHAT NEEDS TO BE DONE AND THANKS BRONCOMATT FOR THE TIPS I'LL KEEP MY EYE ON THE TIE ROD BLOCK I PERSONALLY LIKE PS FLUID OVER ATF I DIDN'T USE ANY TEFLON TAPE AS A SEALANT USED RECTOR SEAL PIPE DOPE AS FAR AS A BLEED PROCEDURE I TRIED THE CONVENTIONAL METHODS THE ONLY THING THAT WOULD WORK FOR ME WAS A MODIFIED VERSION OF THIS
