    Hi I'm in the beginning stages of starting a build. I'm not super familiar with the details of transmission mounting, etc.

    I have a Deutz air cooled 6L912 inline 6 cylinder which I measured the bellhousing mounting pattern to be SAE #3.

    I've also got a divorced NP203 from a 203/205 doubler project I was going to but sort of abandoned.

    I can get an 84 Bronco with a blown motor for free.

    My main question is which transmission would fit the motor? I gather any combo of SAE3 bellhousing, clutch, flywheel should fit together?

    I'm not worried about the trans being "refined" or OD or going over 50mph. Trying to build a bombproof rig to cruise around town and hit the trails.

    Personally I would try to find an adapter from SAE #3 to something else. Everything I've read says the medium duty truck transmissions rob power.

    I'm going to watch this thread out of jealousy lol! I'd love to drop a Deutz into my old well used K1500 just to be different. You've got a sweet project ahead of you!

    I've looked at the bellhousing area again and it looks like theres 3 housings bolted together. I'll try and write on the photos and post them tonight. The engine is still coupled to the generator head so I want to split the cases and measure all the different ring sizes and run the engine without spinning the genny windings.. It appears the one bolted to the block may be an SAE#2 which would make things easier since my Cummins project uses that size and I could use the Eaton trans.

    I really like the Eaton, I have a faceplated 6 speed behind my 3116. Use the clutch to stop and start, but that’s it.

    The flywheel itself looks like it might be 3 pieces. From left to right. The smaller diameter armature shaft, which is bolted to the thick rusty center section, which is then bolted to slightly smaller diameter shiny part with the starter ring gear on it.

    i am not sure how that would work bolting a transmission to the adapters. usually the adapter rings i have seen for say a SAE#2 to #3 are only a thin bolt ring to bring the size down. i am no expert though.

    what is the bolt pattern on the back of what you have labelled as bellhousing 1? it looks like what you have marked as bellhousing 2 is some sort of extra adapter. i don't think you can bolt a transmission to that.

    i can say, i really like my Eaton-Fuller FSO-6406 in my F350. if you do not need overdrive i have seen enough SAE#2 medium duty transmissions around in the couple hundred dollar range to make them easily viable. they may take a little more parasitic loss but they are WAY beefier and made to be rebuild able.
