The Mmarmon-harringtons used a Carrero front axle that was a passenger side pumpkin, with a T-case that had a passenger side front drive shaft. Putting it under the stock F-SD springs eliminated any clearance issues. Quigleys used a BW 1356 T-case and a D60 or D70 axle. Quigley put an adapter plate on the T-case in place of the tailshaft housing to mount the park brake. I'd love to find one of those adapters, as well as the Quigley 10-lug hubs for a D60...

 

The F-superdutys did NOT always have more springs. And More doesn't mean anything either.

Both of my F-superdutys had 5 leaf rear springs and 2 leaf fronts.

A set of springs from a F-superduty I put in my pulling truck were 8 leaf.

It was all on how it was spec'd out

 

FWIW my quigley conversion had no adapter plates just a large drum on the back of the transercase for the parking brake, which doesn't work I should add. Unless that's the adapter you speak of?

 

That makes sense brad. My front has two and my rear has more then a stock f350, which it should as it currently has a dump bed on it.

 

There again.. F350 cab-n-chassis could have multiple spring configurations depending on how it was spec'd out

 

Stock F350 pickup trucks is what I was referring to.

 

F-sd 4x4 conversion

 

Anymore progress? I just bought a D70 front axle, t-case, drum brake and driveshafts from a F-superduty conversion. Now on the hunt for a clean F-superduty

 

Where do you find these deals brad???
Lucky you.
What would you run for a wheel and tire combo.

 

Hi Brad,
No further progress. I don't plow any more, so it's not urgent, and it just hasn't made it to the top of the priority list.
Is the t-case you bought a BW1356? I'd love a pic and some dimensions of the adapter for the brake...
I have a diagrams & rebuild procedures for the brake, if you'd like.

 

A friend of mine called me asking if I had any interest. HE got the front axle from another guy who got it from a pick-n-pull. Then he went back and got all the tother stuff. Its good that people know I collect these trucks. LOL. Going to look at 2 F-superdutys today.

I'll get pics as soon as I have all the parts


Anyone know I I should get the leaf springs too? The fronts that is. Did they use different ones on the 4wds?

 

To my knowledge, the Quigley & Marmon Harrington conversions used the F-SD springs. That's why they sit so high...
The Carrero & D70 axles probably need the clearance. I know that a D60 will work with F-350 springs...

 

The dumbest thing I've done is towed my car trailer loaded drywall with my 04 Ram 1500. I wasn't thinking the drywall was as heavy as it was, but after getting to my destination I called the manufacture and got a weight and figured I had a little over 9k lbs on my trailer. It weighs almost 2,500 empty for a trailer weight of 11,500. My truck was loaded with tools and weighed 6,500... 18k combined... Oh and did I mention the trailer brakes weren't working? The brakes are a bit better with 12" disks in the front and 13" in the rear...

Now back to the thread, sort of... How common are 4x4 F350 chassis cab trucks? Someday I'd like to convert my tow truck to 4x4 and figured if I could get another chassis cab truck I could just swap the bed over. Otherwise I'd have to convert a 2wd frame to 4x4. I know that's been done before. All I'd need is the dually front hub adapters and a parts truck.

 

Here's a little tow truck ****. It's from the sales brochure that came with the tow truck I just bought. It states that the F350 frame is 3/16 whereas the F-SD frame is 1/4"

If I ever convert the tow truck to 4x4 I would also convert from the PTO drive hydraulics to a belt drive. They say you're not supposed to drive with the PTO engaged, but I don't know. Maybe it's a non-issue but I'm thinking I could do a plow and run it off the hydraulics and/or a front hydraulic winch. The rear winch, boom and wheel-lift are all hydraulic PTO driven.

 

The teal truck shown has 3 leafs and is a marmon herrington. STOCK F-superdutys have 2 leafs.

Pretty common. I have had at least 5 or 6 I lost count. Chances are the 4wds will be rotten. Ask me how I know.

Like I said, I have sad several F350 cab-n-chassis, F350 pickup, F250 picks and this will be my 3rd F-Superduty. ALL of them have a 1/4" frame. I don't care what that brochure says
