NO WAY. First off a cummins wont turn the other way as in left hand rotation. Second, it is meant to run sideways with a special oil pan and other modifications internally. Cant be done period. |

Difficult at best and near impossible at worse. The 743 inch 220 Cummins is the same size and weight as the small cam/big cam 855 Cummins, which is very large and quite heavy.
May not physically fit into a 4104. Too long, tall and wide. Would need even more room for the turbo assembly.
Your pancake mill has a different oil pan, oil pump pickup and special rocker box oil squirter nozzles in each head.
These pancake mills were expressly designed for a pancake application, like on my Crown 10-wheeeler.
Conversion parts for an upright positioning are readialy available. Pancake parts are somewhat rare and more valuable.
Your 743 220 Turbo pancake Cummins may have more resale value to a Crown bus owner who wants to change out mills.
Your pan, nozzles, and oil pump will fit on a small cam/big cam 855 Cummins being used in a pancake application.
This means that one can find a good running BC 400 Cummins with Jakes out of an ordinarly older truck...
...and use your parts to convert the mill to work in a pancake position for a Crown Super Coach. This is what I want to do to my 250 BC Cummins.
That is to increase the power from 250 with no turbo to around 400 to 444 hp with a turbo and large intercooler. Problem is I have no money.
Sooossss, the bottom line is it would be nearly impossible to install a 743 220 Cummins into a 4104. To reverse the rotation of a Cummins requires LOTS of different and expensive parts.
The mill is also too big physically to fit into the existing engine compartment. Getting everything else to fit and work correctly would be...
...either extremely expensive or next to impossible. Bet you can sell your Cummins to a Crown or Gillig who needs a good repower. Good luck and....CROWNS FOREVER!!! Henry of CJ |

Okay,
Now don't all shout at once, but is it at all possible for any right hand turning engine to drive off the front of the crank instead of the rear flange? Seems to me that with a couple of keyways in the crank or a spline cut there and a custom hub mated to the driveplate/shaft/flywheel/whathaveyou, it should work fine as long as the front main bearings are big enough to take the strain. With an automatic, there could be less bearing stress as the converter is not attached there, but on the tranny in a V drive, is this correct?
This would allow any regular right hand rotational motor to be retrofitted into a GM Bus, space permitting, as it would be rotating the wrong way as far as the tranny is concerned.
With all the engineering talents about, I am sure someone can engineer it to work successfully.
Just an afternoon thought whilst I await more sand for my sandblaster...........

What about a reversing 730/731 transmission? I know some were made, so that they could run right hand engines. They may be scarce, though.
Also, many marine applications used one rotating each way in twin setups. If you run down the makes that were sold that way, you could find out which ones would work.
For what it's worth.
