Oh Shoot! Didn't know this!
Oh Shoot! Didn't know this!very true... BUT, they can both be easily wallowed out and replaced with a quality size holders, usually from boats.
I got to thinking. There’s a small block 4x4 ZF5 in an F250, but the tailhousing is broken. Why not take the 4x4 rear off of this IDI one and put it on the smallblockThe ZF with parking brake attached IS a 4x4 model. The parking brake attaches just like a transfer case would. But they are the diesel bellhousing and likely the narrow gearset with a mere 4.14 granny gear. I recently left one on a f Superduty
As long as its the same s5-42 or s5-47, it should work. Also, great thinking! Thats a true scrounger mentallity!I got to thinking. There’s a small block 4x4 ZF5 in an F250, but the tailhousing is broken. Why not take the 4x4 rear off of this IDI one and put it on the smallblock
So that’s what I started to do today. I was able to get the brake drum off, and removed the crossmember and all the bolts holding that tailhousing on. Unfortunately I didn’t have a dead blow hammer and I couldn’t pull it off, nor did I want to risk breaking it with my BFH, so I left it for next time. Hopefully some SOB with the same idea doesn’t screw me.
I did get the crossmember.
Now you’ve got me worried a bit. I’m pretty sure the F250 with the broken rear is a -47 because of the heavy ribbing. I’m not sure about this F-Superduty. Were there changes in the bolt pattern at the rear that wouldn’t allow the swap? I always assumed the reinforced case and maybe some better internals were the only real differences.As long as its the same s5-42 or s5-47, it should work. Also, great thinking!

I cant say for sure. They may mate up, they may not. Internals may have a bit different specs, leading to a different case half. If the F-superduty has an IDI, its not a s5-47. IDI was last used on early 94s and the S5-47 started in 95.Now you’ve got me worried a bit. I’m pretty sure the F250 with the broken rear is a -47 because of the heavy ribbing.

just get it anyway someone may need it and will pay up for it. You can do a JY test fit so they dont charge you extra.Now you’ve got me worried a bit.

The bore depth for the shift shaft to slide in differs between the -42 and -47, as well as the shaft itself. There is a deep and shallow bore, on the -42 the deep one is in the front case half, the -47 it is in the rear. You can run a -42 front with a -47 rear, but not the other way around.
Also, changing the tail housing requires a complete disassembly of the trans, it doesn't just bolt on the back end.
for diesel: Just to add to this, only a big block gasser will work, the small block is a few inches longer.
Lol i bought one, recently rebuilt, for 1800 bucks before i found the junkyards... But it came wrapped in a running f250!I know you can swap ZF5 internals from case to case. Lot of guys in the IDI world swap the wide gear sets in for better ratios. 4x4 zfs go for pretty big money. I see them listed all the time for $1800 depending what you can get them for I would snag them both.
Twas an 88 F250 with 351w and a ZF5, d44HD TTB, FF 10.25, a 99 chevy seat, open headers, and a big honkin cattle pusher. Eventually it will become a full on crawler, bobbed, dovetailed, SAS'd, exocage, flatbed thing. I did actually drive it home at 70 mph. That was about 5 years ago. Fun fact, it had brass bolts holding the trans crossmember in. Its a manual truck that someone used an automatic tunnel cover on and chopped a hole in it lol.maybe its a California thing, everything is more expensive here. but the few I have seen on CL have been in the $1800-2000. It is rare to find a running truck in that price range anymore. If you do, it is beat to death.
