Greetings,

Doing some brainstorming about using a spare 617 engine for another application. What manual transmission/bellhousings will mate to it?

Are any of the manual transmissions used in the Unimogs compatible?

Thanks for all comments,

That engine has been successfully applied to the 404 series Unimogs. I can't recall for sure if it bolts in or not. I am pretty sure you need an adapter. I am also pretty sure the adapter is easy to come by.

What transmissions were available for the 404? Any sources where they might be available in the States?

Howdy Bruce,
If you are going to hook your 617 to a Mog tranny my questions are; Are you going to use any other parts of the Mog?¿(frame, driveshafts or axles) Can you mention what other application you have in mind without giving away any secrets that you don't want to let out?¿ The reason I ask is the engine /tranny on the Mog is part of the structure along with the driveshaft and frame that hold the axles in place. Another unique thing about the engine/tranny is that the engine is connected to the frame by a bolt up front and the tranny is connected to a "clamshell" that is put over a cross member of the frame. (if you can picture that you are better than I am ) Hope this helps. If you can give more info I can ask some people that have done some conversions.

Considering using 617 as replacement for '52 military Dodge M37. Please see my post (today) in the Diesel Discussion forum. I'm concerned that the 4-speed manual trans used in the 220, 240-D type 123's might not be heavy duty enough.

I haven't been able to determine if there's any way to adapt the 617 to the original Dodge bellhousing to use the old clutch & trans.

Thought that a 'Mog tranny would be heavy enough.

I'd also be interested in hearing anything about using a 617 in a 'Mog, as I'm considering picking up a 404.

Howdy Bruce,
The 404 tranny is 6 foreward 2 reverse. The engines are the gas engines m 180 & m 130. The 180 has 90 hp & 120 ftlbs of torque. There has been discussions about the ability of the tranny to handle sustained speeds over 55 without damage. If you want a Mog with a diesel look at at any other model. The most popular is the 406/416. G-Man can comment on them better than I can. Adapting any Mog tranny to a non-Mog frame would be a major job. As they say anything can be done with time and money As for sources you are in luck. The one website you need is www.rockymountainmoggers.com/unimog.html
Go to the Mog links and look around. Several Mog dealers are; Michael Smith of unipaser, Sean Philyaw, Chris Elliot & Scott Ingham. Another great source is Eddie Runners Mog mailing list. I am trying to bring some of the people in that list to this forum. (so if you go there don't abandon us ) Hope this helps. Good luck in your search.

One thing that has been overlooked is that the mog has the transmission and transfer case built as one unit. One rather large heavy unit in the case of the 406/416. But even in the 404 it is all one piece. Frank is correct, it would be a real bugger to fit it to anything other than a mog.

BW,

I've swapped a number of manual 240D transmissions into Turbo Diesel 123 Series Mercedes and we've never had a problem with the trannys holding up. Like you I've considered staying with the 617 engines and putting them in everything else I'm interested in and I'd go the 240D tranny in an instant.

I've five 123s and all have been converted to manuals. Everything from 240D, 300D and 300DT. Go for it.

Although I do not know the specifics(ie numbers) one thing that has not been mentioned thus far is the fact that the Unimog transmission output is likely at too high an rpm for use in another vehicle without the Unimog axles. Unlike most vehicles, the Unimog tranny output goes through two reductions, the differential and then the hub gears.

Also, the connection to the tranny at the output shaft is not like most other vehicles, so an adaptor would have to be fabricated, this is not a simple fab and bolt- in job!

As was said before, if you got the money and the time you can do anything.
