351m / 400 transmission & TC options in early bronco
#121
got the floor patch in with the shift boots, works pretty good but will be taking the floor piece into line x to match the floor and help the heat and noise.
On the lookout for a bigger shift boot, will have to keep my eye out at the boneyard
so far so good, no issues and hope I dont have any in Moab in a few weeks

well after about 4000 or so miles the throw out bearing finally gave up the ghost and barfed its bearings out at the bottom of the inspection plate. I will have to pull the transmission off to see what caused it but i suspect its engaged just a bit too far and finally gave up.
I guess my two options are to cut and weld the fork so it angles back just a bit... or put a spring on the other end of the fork to pull it back off the clutch pressure plate. I am favoring the cut and weld option right now.
Any other ideas? The dodge bearing which i used (i think), seems like its the better option of the two to try as its thinner. I will check it against the other throw out bearing I bought...
Other than the throw out bearing its been a great swap so far. Consistently getting 14+ MPG, easier shifting and much easier on me and the Bronco when driving long distances.
I was about to pull it into the garage to fix the rear ARB as its leaking and suspect that its the seal housing or seals... have a feeling the line was installed short and not allowing the seal housing to move - which i guess its supposed to so will kill two birds with one stone

Glad it is working for you. FYI, the fork is really hard metal, so there must be a large force on it. Make sure you reinforce it.
I'm thinking your clutch may have done what mine did and took the seal out of the front of the bearing. The bearing doesn't last long then.

is the seal a little ring around the back side where the fork sits? i noticed that a couple of weeks ago it had separated from the bearing. I don't remember which throw out i used but will take a look, If i don;t have to modify the fork that would be great... I guess i will know once i get everything apart this saturday.

I pulled the transmission and swapped in the dodge throwout bearing. The old throw-out bearing basically disintegrated into its basic pieces. It looks like there was quite a bit of heat generated which could mean it didn't like riding the pressure plate all the time but as pointed out I think the clutch fingers also had a role to play. I would need CSI to really find out what went wrong as there wasn't too much left as you can see from the pics.
The new dodge bearing is a bit thicker and it does ride the pressure plate quite a bit. I drilled a couple of holes in the fork while I had it out and plan on putting a spring to back off the bearing slightly. It only needs 1/8" or less to stop it from riding the pressure plate all the time.. should help.
Crossing my fingers as its not easy to stuff that zf back in an early bronco with a 400, takes some creative engine strapping to tilt things..

The new throwout bearing is behaving itself so far. Have another 5000 miles on it or so, don't really know as my Odometer isn't accurate.
I would assume this has been posted elsewhere but Tim Meyer is now producing a kit for this conversion that includes a thicker flywheel...
