47-55.1 Danforth Cross Member Install

[Hampshire]

Be careful with those specs from Borgeson & BTW, DWCSR has it right - the fractional spec, etc. is where it is at.

My first rack (2.5 "sport") with the Borgeson recuced pressure pump, hoses and metric hose adaptors (their spec) leaked at the rack - though possibly due to Borgeson sending me the wrong washers.

When I went with the 3 turn rack, I went with fractional adaptors and white O-rings from an outfit in California (similar to what Speedway sells). Works great.

Bottom line, Borgenson pump & hoses are fine, but don't follow their advice or use their adaptors - everyone but them has gone fractional.

Another pressure adjustment method....

I used the Borgeson 925102 Ford 79-97 rack to GM Type II pump and the speedway imperial fittings. -AN fittings are still imperial so the hose ends were ok. You will have to use the brass ferrule from the kit in the pump

So I need the hose kit and an adapter that goes from 9/16-18 to 14mm-1.5 for the pressure and 5/8-18 to 16mm-1.5 for the return?

The hose kit is correct length and angle on the hose ends with the wrong fittings for our rack

I used a the Borgeson hose kit and the rack fittings from speedway 9104047
The hose ends on the hoses are AN and will fit the speedway fittings.

fittings 9/16-18 to -6an and 5/8-18 to-6AN fittings.

You can get a ford pump or add the reducer into a GM pump. I don't now what ford pump you would need

Yes you were the one that put me on the trail for the 3 turn rack, I had forgotten your user name so I couldn't give you your due credit

[Coach529]

I have a rack and pinion and tie rod ends on the way, hopefull they will arrive tomorrow!!

[Coach529]

Still plugging away on this install.

Threw the motor in to mock up the rack and pinion set up.



The mounting on this rack was offset to the drivers side which makes mounting a bit more troublesome. I picked up some 4" x 4" x 3/16" tubing to make some mounts out of.

Scott suggests a 3" notch to clear the rack. This WILL NOT work with a Ford rack. I had to open up my notch to almost 6" to clear the Ford rack. Frustrating to cut apart something that was finished.



I had to remove some material on the passenger side of the crossmember to clear the rack. I got a little overzealous with the skinny wheel and sawzall.



mock up





Making brackets





Tacked in



Fit test. I did end up opening up the notch after this.



Both side welded in and the relief boxed in. I just need to rebox the bottom of the notch!!

That's just what I did on my install. In fact I would almost think I was looking at the one I did.

I had studied your install a lot before I started mine. Thanks for the tips!!

Has your customer had a chance to put any miles on?

Curious about his feedback on the front suspension.

Yes, with the new rack (3 turn) it drives great. I like it and he likes it which is the important parts. Thanks to the input of all the guys here that helped get it figured out I think this is the go to cross member for me in the future for AD trucks.

The truck with the Danforth front end and the 67-72 trailing arm rear makes it ride nice and handle like a newer truck similar to a 2000 up Silverado but smoother on the Interstate. I think with bags it should ride like a Cadillac

Turning radius is also very good

one last question. No bumpsteer issues?

[dwcsr]

none at all and I was afraid it may have but like I said it drives great.

Thanks for putting my mind at ease.

You'll be happy with it I'm sure.

I am right behind you on starting my Danforth install, so I am watching very carefully each step.

I may have to talk my son into bring his plasma cutter over when I need to notch the cross member for the R&P.

I am not going with bags so mine will be closer to what dwcsr build.

A plasma will definitely shorten up your build time......I should have NEVER started this project without one.

[Coach529]

Dave, when you tap the tie rod ends to 9/16 did you have to drill them as well? Or just run the tap through?

Thanks,

Mike

Great. Picked up a tap last night.

I am trying to buy some u-joints, but do not have access to my rack right now. Is the rack a 3/4"-36 spline?

[dwcsr]

Yes 3/4-36

[Coach529]

Frame is painted and the rack is in.





I screwed the tie rod ends on until they bottomed out and checked the toe in. Looks like I am about 1-1/2 too wide in the front.

I need to verify again tomorrow, but looks like I will need to trim the rack a bit.

[dwcsr]

As I recall I did as well but there is more than enough threads to do it
