Front Dana 60/61 swap

Postby slick » Sun Feb 19, 2017 10:20 am

Just picked up a 1990 Cummins 4wd chassis. I think I will eventually put my Crewcab on that frame . For now I'm thinking I want to put the 60 under my truck for now. I really want the disc brake swap. I have the master and booster from my 93 donor. My big question is the steering. Am I crazy to think I can turn this front end with my original manual steering box? I know I have to move the shock mounts, but I have also read that with the right components the original steering will work?
Thanks

I had a 78 W200 club cab with a Dana 60 front. I converted it to manual steering using a box off of a 72 Dana 70F equipped W200. The box was made by TRW. They are scarce.

Tire width (contact patch area) has a lot to do with how much effort it takes to steer. I had stock tires/wheels. It worked fine.

I sold the truck to a member (Doug) of the PW forums. He may still have the manual steering box.

I just reread your post. I forgot you're not talking 72-93 but Sweptline instead. What manual box to you have now?

Slick,
I think if I were planning on swapping frames later, I would leave the axle where it is. It is way too much work to just gain disks.
The short steering arm on the 60 ramps your ratio up a lot when combined with the long arm on the sweptys steering box (even a W arm).This makes for about an added 1/3 extra steering effort. There isn't enough room to swing a longer steering arm that could be sourced from a ford axle.

Cheers
Doug

Thanks Doug, I was hoping you would chime in. That sounds like solid advice. The follow up question in the future will be asking if I should stretch the Cummins frame or move everything to my Crewcab frame . I'm leaning towards grafting my 2 Cummins frames together..

I think you need to talk to the master in Hubbard Ore. for the answer to your 2nd question.I think Powerwagoncrazy has done it both ways. :thinking I assume you will be using a 6bt?

Through a lot of trial and error with castor and drag link angle it can be done. I'm using a rebuilt manual Red Head steering box (for my 62 W100). At first, I adapted a drag link to use manual steering with the factory box on the Dana 60 front. Steering was tough (285/75r16 tires) and had a good amount of bumpsteer (due to drag link angle). I ended up integrating the stock style sensing valve into the drag link and adding a PSC hydraulic assist cylinder (1.5" bore x 8" stroke). It works very well but looking back, if I was starting over, a frame swap/graft would be considered.
