I know this might be against all things held sacred in Forddom but ... I am working on making a trike ... A friend gave me an F250 4x4 6.9L diesel for the drivetrain ... I would like to make it a dual axle setup for increased load capacity ... What I need to know is what other years and models used the same rear end ... I am on a sorta budget and would like to not necessarily get the second axle from a more expensive model ... I was thinking about getting 2 fresh matching 9 inch rear ends but that is a bit pricey ...
If anyone has any suggestions concerning possible trailer or motorhome axles that I could use instead I would greatly appreciate hearing them ...
Are you saying you'd have a motorcycle front end, some kind of midframe, and then TWO rear azles from a full size truck out back?
Most trickes would have something narrower than that out back, not to mention something lighter.
You say you want two axles for load capacity? how much are you needing to haul, and where would you put it on a trike? the axel out of that truck is probably good to 4000 lbs or so.
If you really want tandem rear axles for athetic reasons, then I don't think you need two D60's. Much cheaper to grab a couple of axles from a crown vic or lincoln. Actually, come to think of it, a Lincoln frame would be a great place to start for this project. It's already plenty long, so I doubt you'd have issues fitting a tandem axle in the rear. Plus, you can pick up early 80's town cars for dirt cheap and they'd have a V8 motor. A tandem axle trike with a 460 would be a sweet project.
The hardest part about a true driven tandem axle is the drive. Do a search on google since I can't remember the site, but there is a place that makes a gear box that mounts on the front of the first drive axle, and lets the power go straight through to the first axle, and also has a spur that sticks up and gives room to put another driveshaft to go around the first axle to drive the second.
I believe there is also a place who custom modifys the front axle to give an output on the back of it, to drive the second axle.
For looks purposes, just a dummy or bogie axle would probably serve your purposes without all the driveline engineering.
I was thinking of just driving the front axle ... I like the idea of 3/4 tonne axles because even if I never come close to their combined weight capacity they will last longer ... And if they match then I will have spare parts in an emergency ...
If I really had a wild hair I might consider putting super singles on it somehow ...
You'll have a hella time turning it unless you make the rear axle have the ability to
turn either with a actuator or just free trailing kind of like a dump truck air axle.
I would use a 4x4 front axle for the rear most axle and a transfer case turned in
reverse and clocked so the front drive is up on top, So the front drive shaft is low
and the rear driveshaft goes over and to the side of the forward axle. Or you could
go with rockwell axles and have a power divider lock. The ability to lift the rearmost
axle would also help when turning kind of like a cantilever trailing arm with airbags or
if you had a flat swap a tire from the rear axle and just carry the rear axle up with the
flat on it you would basically not have to carry a spare since you have two already
there!!
