This is a rear engine TC2000 8.3 Cummins with the MD3060.

You can see the coolant filter in the engine casting at the top rad hose.







This is a Thomas rear engine 8.3 Cummins and the Mt643.



The Blue Bird has strait frame rails all the way back to the bumper.

The Thomas drops the frame 5 feet from the rear of the bus to cradle the engine.

Both buses would be simple to build a hitch for. (This was a recent topic)

The Thomas has less room in the engine bay. This also means more room inside the living space.

Both buses are 1996 units.

Nat are they using conventional trannies and then a dividing box or?

To reverse drivetrain spin back to normal for rear end?

Never looked at one, have seen pictures of older v-drives???? I guess my question is how do they work?

I would love to put an 8.3 and a real auto in some day (FE of course) and if the RE are conventional rotation etc, might be a cheaper swap for me

I had just assumed the ring and pinion in the axle would be reverse cut, like those in the front axle of a 4x4 vehicle. My RE doesn't have any intermediate rotation direction reversal box. There isn't room! The drive shaft from the trans to the axle is only about 2-3 feet long.

Not all the Birds are like that. On the rear engine towing thread we learned that somewhereinusa's AARE and my CSRE Blue Bird both have a section of frame dropped in the way you described for Thomas -- these two samples, at least, don't have single-piece frame all the way to the bumper.

On a 4x4 the transfer case reverses the rotation between front and rear

If rear input is spinning clockwise at pinion, due to only having 2 gears or a chain etc, the front shaft spins opposite so it turns pinion counter clockwise

Do rear engine buses just have pinion on opposite side(left/right) to make direction change? Is housing spun 180* and .... Crap I need to research now..lol

I am curious

I agree, when we travel route 12 on outer banks mine w/5.9 will run 75.....any incline slows me down, tranny is big problem for me A545

True, that's why I mentioned in my post that those buses were both 1996
units.

IMO I'm confident that any rear engine bus won't be hard to build a good hitch for.

It's all in the rear pumpkin. Not sure yet what is going on in there, but on my list to find out.

So yes all rear engine buses with DT466, Cummins 5.9, and 8.3 use the same transmission as the front engine buses.

That's why the next 8.3 MD3060 combo I find is going in a rat rod with the engine completely exposed.

A little car and a tow bar to tow it with behind the bus. Or a small motor cycle, ect to go fetch things, scout out, get parts if you break down, ect. I hate being away from home in a strange place without transportation.

Others may chime in with the little stuff. However this topic has been covered about twice a month in recent threads in the hello section.
