JunKeBluB2 Hydro-Assit - JunKeBluB2 - 10-07-2007
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!
Ronnie

very nice Ronnie!!! When I get my junk done, we will have to go to Gulches to test out each rig!!!!Chuck
JunKeBluB2 Hydro-Assit - JunKeBluB2 - 10-07-2007
ok Chuck but mine's the junk & your's will be grade "A"
JunKeBluB2 Hydro-Assit - krazybronco - 10-08-2007
you are building one sick b2 man so glad i got to wheel with you
JunKeBluB2 Hydro-Assit - JunKeBluB2 - 10-10-2007
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.
JunKeBluB2 Hydro-Assit - krazybronco - 10-10-2007
sweet when i get 35s your building me a doubler and hydro assist you just dont know it yet
JunKeBluB2 Hydro-Assit - blazinchuck - 10-10-2007
Ronnie, I think you should get up with Matt and do some write-ups for BIIs in broncodriver mag :wink: .Really,Chuck
JunKeBluB2 Hydro-Assit - krazybronco - 10-10-2007
yeah the b2.org guys would love it

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
