1975 F600 Front Diff and Transfer Case
I am wondering if anyone has pictures of the front diff or of the t-case opened up or one of those “exploded views”.
Front diff is a ford 5000lbs and the t-case I’m not sure, I don’t know what these came with.
The trucks info (thanks to numberdummy):
F66 = F600 4WD (gas).
D = 330 2V Heavy Duty FT engine.
V = Kentucky Truck Assembly Plant.
V63764 = 1975.
158" Wheelbase.
F660 = F600 4WD (gas), 21700 lbs. GVWR
4B8
4B = Black Heavy Duty Vinyl / 81 = 81A Standard Cab.
P = Borg-Warner T-19 4 Speed Manual Transmission.
62J:
62 = Rockwell model F106 Single Speed Rear Axle / 6.20-1 / 15,000 lbs. Rear Axle Capacity
J = Ford 5,000 lbs. Capacity Front Axle with Power Steering.
21,700 lbs. Gross Vehicle Weight Rating.
A68009:
A6 = FoMoCo of Canada Ltd., Western Lincoln-Mercury Division, where the original selling dealer ordered the truck from.
8009 = Domestic Special Order number, truck ordered special by the original purchaser, not "bought off the lot."
It appears to have been converted to run ten lug wheels, super singles, military- Am I correct?
My front axles are Fds-75.. or 7500 pounds.. if yours really are 5k then they must be the predecessors to mine
My rears are the same as yours
Transfer case is rockwell
They are both in the heavy duty ford parts books
Bill has the parts diagram
There is a youtube video.. two part..on rebuilding the axle
The brake drums are gold and are no longer made.. protect them
Have fun..looks like a cool truck
You need locking hubs...

I’ll have to check if that axle has been swapped out then! I wasn’t told it had been when I bought it but you are right, it is running 53” military tires.
I'll post the 3 T/C pics in a following post...later today.
