Big round disc on back of transmission

[nyteshades]

Long story short, I bought another 89 f350 for the motor and zf transmission. This one is a 2 wheel drive. There's a big disc on the back of the transmission that the driveshaft goes into. Am I right in thinking this is the parking brake and the "regular" 2 wheel drive transmission just had a yoke on the tail shaft? In other words, the big round disc should unbolt and I can bolt my transfer case up to it? Right?

Sounds like it...I thought that was an F-Superduty thing only...hm.

I dunno man....I'll post pics tomorrow once I have the truck in hand.

Sounds like a superduty tranny. If it is its actually a 4x4 tranny with an ebrake bolted to the back instead of a tcase.

The tranny mounted parking brake looks like a drum brake on the back of the tranny.

the trans that can take a transfer case and the parking brake at the same time is indeed the 4wd trans. the genuine ZF5 for the superduty(88-97) has a deeper first gear.

By deeper, do you mean taller?

5.15 or 5.72 iirc

Am I right? Is this trans going to accept a tcase?

If you unbolt that disc and there are 6 bolts for it plus an alignment pin, then I would say yes, it's a 4X4 tranny.

You are correct

You can sell the park brake setup for a good penny if it works good, they are not cheap new.
