Zf5 cross reference between IDI and psd.

Thank you!

I’ve got the T-19 in my ‘85 6.9 F250, and picked up a ZF out of an F450 with the parking brake. Initially I was going to use it and convert to rear discs, but when I saw how steep the reverse gear is in the ZF, I realized a transfer case would give me a real nice granny reverse when I need it!

I just emailed that guy on craigslist. I didn't see a transfer case on that did you?

I don’t think so, you should be able to find one for pretty cheap

Yes he said it is still available. See if he will ship for me. Might have to stick it on a small pallet

Yes, the f350 dump truck I worked on had that beefed up frame. Since you have a cab and chassis truck, your truck is completely oddball from the cab rearward compared to a regular dually pickup. The frame is more narrow, the rearend housing is more narrow, you have a large stack of leafs in the rear but they are narrow also. A pickup bed will not fit on your frame if you ever had that notion.

The little f350 dump I worked on was 4x4 also. If you take the other guys advice and install a tranny and transfer case, then you will 1/2 of the way to 4x4. Later on you could swap the front axle and have 4x4, though I am not sure what your front suspension looks like now. Does it have leaf springs or coils up front?

Yes, I feel the truck is an odball and that is fine though. Have not conteplated ever of putting a truck bed on it. But have thought about fabricating a custon utility bed for it. You're absolutely correct, the frame is very narrow along with the spring stacks. I noticed that trucks of late have much wider springs. That is the standard now I suppose.

Oh man!!!!!!!

I prefer the 42 ratios with a tcase. The 47 is supposed to be a touch stronger.

S42 ratios:
4.14, 2.37, 1.42, 1.00, 0.77, (R)3.79

S47 ratios:
5.08, 2.60, 1.53, 1.00, 0.77, (R)4.66

So that s47 has a higher 1st and reverse ratio. I will stay with the s42 trans.

So does the higher number mean that 1st and reverse are lowered geared?

Higher number means a lower gear. Also if you get the zf 4x4 tranny have him put it on a skid and ship it through Fastenal. They are by far the cheapest way to ship big items as long as you don't mind picking it up at one of their stores. I just shipped a complete 6.9l from Harrisburg, PA to Texas for $300!

Now that right there is some good info! Thanks for the heads up on shipping!

Tc, do you have a zf5 42 4x4 in your arsenal that you might part with? And if so how much?

Also, am looking for a spare 7.3 idi with low time (and if not low time, low abuse) that I can rebuild for an eventual swap out.

all the ones in the pic I consider "core" grade. you will need to rebuild them. i haven't put any of them through the gears while under power to say they are "good used" or needs rebuilding. the shipping will kill you as a result. To answer you question ahead of time, no I do not have the time to build a crate for it and send it through Fastenal.

I understand. This guy on craigslist has already sold the transfer case for the listed zf5 so I am weighing is it worth buying what he has and begin searching for a transfer case or just backing off and waiting for a complete tranny with transfer case. Or...... just rebuild what I have and struggle with the high geared reverse. Or rebuild my zf5 and bite the bullet and get a GV under drive/overdrive unit. Just not sold on GV's product for towing.
I have an F450 1996 14 foot flat bed with a 7.3psd with only 156k miles that I would use to trade someone for a good zf5 tranny and a spare 7.3 idi engine.
Am sold on the idi engine so may go that route.
What are your thoughts on that?
