Completed my T-19 to ZF swap today!!

[Kevin 007]

It went pretty well, I did end up removing the starter and loosening off the exhaust on both manifolds to get the trans lined up. Redrilled for the trans crossmember, I used the ZF crossmember. Left the floor pan alone even tho I had the one from the ZF truck. It barely lifted and I had no need to modify the hole for the shifter. I used the T-19 stick/boot as I like it better and did use an extra sheet metal screw to hold it down snug where it lifted a bit. Used the slave that was on the truck....I hate compressing the rod with my hand and quickly trying to get it in place. So I used the hose clamp trick but that can be frustrating to. Driveshafts went back in no problem, the 1345 t-case bolted right up and I used the forward most mount on the ZF for the 1345 shifter. I left that hole in the floorpan alone also.
Only thing that I didn't get pack in was the darn flywheel dust cover/inspection plate. I will have to fight with it again tomorrow I guess.

I used the AMS 12'' clutch (07-131) and AMS solid mas flywheel (627325 I think). The rollover noise is not close to as bad as I thought it would be. No worse then the noisey TO bearing that was in front of my T-19. I think the rollover noise is worse from outside then inside the truck.

Anyways, Im very happy with the driveablilty of the ZF due to the overdrive gear. Im sure it will help out on the MPG's and less wear on the engine. My days without and overdrive are now behind me And im going to guess that it took me about 12 hours total. Thats not rushing but not lolly gagging either.

Sweet! Im glad you were able to use the 4spd parts. Is your truck a 4.10 or 3.55 rig? Im sorry but I cant stand 4spds in these diesels. 5spd all the way

Its a 3.55 rig so the MPG's should be pretty good with the OD. I don't tow anything more then 5k so I have enough power without a turbo to not need 4.10s

Regards

Awesome you'll really enjoy having the OD for sure.

Where are the pics?

Guess you got parts to sell now with the old trans/bellhousing??

Anyway have fun with the new transmission

 

[Kevin 007]

Hands were far too greasy for my new camera that cost so much that I don't even want to talk about it . Yeah I have all the T-19 parts, trans, bellhousing, flywheel (warped), clutch, crossmember. I planned to hang on to them but if someone is in need....I will have no problam selling them pretty cheap or trade for W.H.Y. Do you need any of it Al?

 

[riotwarrior]

Nope no need, however I'm always aware of whats out there

Still looking for Bronco diesel engine yet!

 

[Kevin 007]

Got the inspection plate back on, slipped in there no problem. I don't know what my problem was the first time around.... Maybe after laying on the ground fighting with transmissions for hours on end took its toll on me and I could no longer funtion

Also another thing worth mentioning is; the ZF clutch makes for a much easier pedal then the T-19 clutch. So im going to assume that its also easier on the slave and master.

 

[Kevin 007]

Ok im a couple thousand miles into it now and im still liking it. The lower hwy cruising rpms are MUCH easier to deal with then the direct drive T-19. I gained some MPG also but still have not figured out the exact numbers. The Trans and clutch seem to be doing just fine. One thing however, when im parked on a hill in 1st or reverse; the truck will creep a bit if the hill is steep enough. It takes much less of a hill to make it creep then with the T-19. So what does this mean? Weaker pressure plate? weaker clutch springs?

 

[NO_SPRK]

Hmmm.. since the first gears on both transmissions are so close im also wondering why it would want to roll. It wouldnt be clutch springs. And I dont see how it could be a pressure plate.

I have no idea

Yeah kinda strange isn't it. The clutch does not slip at all under load, I even pulled a travel trailer a ways just to make sure. And I do have a adjustable master cylinder pushrod and its not adjusted too tight as to partly disengage the clutch. So im also at a loss with this..

Bizarre that it would roll when parked on a steep hill. Something is slipping. Either clutch isn't fully engaging, pressure plate is very weak, or disc is totally oil soaked or otherwise worn out/broke. Any of these should result in slipping under load if it'll slip parked on a hill. Very curious to see what this turns out to be.

 

[Kevin 007]

I hope it turns out to be nothing . There shouldn't be oil soaking issues as everything was bone dry in there when I did the swap and no leaking. The disc is brand new and not worn. So maybe a bad pressure plate. Im going to keep running it and see what happens

Left the floor pan alone even tho I had the one from the ZF truck. It barely lifted and I had no need to modify the hole for the shifter. I used the T-19 stick/boot as I like it better and did use an extra sheet metal screw to hold it down snug where it lifted a bit.

Any chance of getting any pictures of the floor pan? Also, do you have a body lift by chance?

I tried putting the T-19 floor pan insert on my truck when I did the ZF conversion, and when the pan made contact with the back of the transmission, there was a solid 3/4" left to go before making contact with the floor. I might have been able to modify it with a BFH and get it to work, but I think the clearance would still have been too tight (I imagine that, if the insert's touching the transmission, that's going to transmit quite a bit of noise. I already had a ZF floor pan insert, so I just cut a hole for the 13-45 shifter lever and all's been great

What thread sealant did you use on the flywheel to crank bolts. they require a thread sealant or oil from the crankcase will leak past them. Those drilled and taped holes in the end of the crank flange enter the oily side of the pan so hot ol is splashing on them all the time. The torque is 47 lbs too.

 

[Kevin 007]

The bolts came with an orange sealant on them. I asked about it in a different post prior to doing the swap and folks seemed to agree that this was adequate. I put a couple drops of blue lock tight on the bolts, cleaned the female threads in the crank with brake clean and torqued to 47lbs
