my ZF5 install
 

well just like the title says, time for the ol e4od to get the **** out lol

i didnt mind the e4od it was nice and everything only let me down twice (crawling low speeds up mountain trails and overheated) but after driving my 93 with the zf 5 i like having more control of things and more options for gears.

as of right now i have everything BUT:

*extended rear drive shaft
*new master cylinder???
*the 87-91 reinforcement plate (link thanks to ididieseljohn Terrapin Manufacturing)
*SMF from south bend (SOUTH BEND SINGLE DISC CLUTCH KIT FORD 7.3L IDI TURBO 1944324K | eBay)


im debating just using the stock DMF for now. any thoughts on this?

ill be starting this swap hopefully this weekend. just need to get it done before my truck hits the dyno...thats all im worried about

more pics to come

Don't get ahead of yourself. We have to put my lift on first!

Did you get the ZF crossmember? You need that.

How many miles on that ZF?

If is were me, I would go with the SMF. That dual mass will let you down, and I figure do it right the first time.

Yep have the crossmember, it came from a 1990 f350 CC with 180,000 mi that got hit and took some body damage. Is the DMF really that bad? I've never drove one with it. Might have to research it a bit more.

I figured the hardest part would just be getting the whole system changed to the zf. Dropping tranny isn't an issue so when I do want to get the SMF I'd already have all the hard stuff out of the way? I'm sure it would last a couple weeks?

Unless its old and worn out, the DMF should work.
I think a lot of people don't like them because they are expensive to replace. The engineers must have designed them for a reason, otherwise why would ford spend a lot of money to put them in?

I think a lot might have to do with how your use your truck. A DMF might not hold up to heavy towing like a SMF would. There is a slip clutch in the middle of the DMF to prevent tranny damage if the engine overtorques. If that slips and overheats, the DMF is useless, I had that happen to mine. However, I have no idea what previous use my truck had. It had a fifth wheel in the back, and was bought be a landscape company so could easily have been abused for 150K+ before eventually being bought by me.

I replaced mine with a new DMF (at a very luck bargain price) and have been happy. Lots of people go with SMF and have gear noise, lots have no gear noise. Do a lot of searching and do what you want, but my guess is the DMF will be just fine.

Thanks! The 91 doesn't see much load, only when someone gets stuck in some mud or snow then I give them a little tug.

How long do the trannys themself last? The guy said it worked just fine....but then again it was Craigslist...

Check for play in the DMF before you remove it from the old motor. IIRC Dave S stated that you should not be able to turn the starter gear part more than 5/8 inch, when rocking the motor back and forth by hand with the starter ring.
I personaly don't like the DMF, as it cost me a tranny on my 97 when the center bearing crapped out, throwing things out of ballance and it cracked the bell part of the ZF. That said the DMF on my 90 lasted around 135000, and it spent quite a few of those mine pulling a 20' stock trailer.

My F250 is still on the original clutch and flywheel..... is the DMF done? Absolutely :-X04 you should hear it knock when you turn the engine off, but never let me down for 377k miles!


I'm going back DMF as well, I've heard what that annoying gear rollover sounds like with the single mass, no thanks. Sounds horrible.

Mine still works great with 377k miles. Reverse not so much though, grinds alot sometimes. Been doing that for years though.

Never had any maintenance, and 1 and only oil change around 150k.

ok so update, got lil red sleds lift kit installed then had to go to work for a bit. looks like ill just run the DMF untill the clutch needs replaced then do the SMF. my 93 has rollover noise and loud shut down if the clutch isnt held in

pics tomorrow

SWEET!!!! Welcome to the ZF side of things!!!

So for the new master cylinder...what exactly is needed? The booster? Or the MC?

Or is this what I'm talking about?
