I was playing around in the barn and was looking a one of my jeeps and notice the motor sits about 6 in"off center toward the drivers side. No wonder the Willys has a lean . Just thought that was interesting....... |

Too many jeeps.....GOT JEEP ?

Yeah, pretty crazty offset under there!
When I was installing the V6 I had to cut the transmission crossmember and move it towards the center mor. The bigger engine visually exagerated the offset

You restoration guys kill me !! See, there's a little more to this 'modification' thing than just a torch and a bigger hammer. (this is great!)
Now, figure out where the rear diff would have to be if it weren't.

Still funny though !
And yes, I agree, the reason for the 'lean' is built in.

So now...since the result of that design was the lean to the driver's side, what would have been involved, had they offset the motor to the other side? Rear diff would have to have been flipped, transfer case would have to be on the other side, etc....would it work if that had happened? Would everything have still cleared? (I'm betting that there was some other reason that the motor was offset to this side, rather than it having been an arbitrary choice.)

The transfer case isn't made to be "flipped".....but if you're asking would it have worked if it was 'designed' that way (i.e. motor offset to pass. side and transfer case drop to the driver side) then I guess it would have worked but it wasn't designed that way. They did change all that when they designed a 'straight through' transfer case...
I figure they were using stuff that was already 'designed'.
Jack, remember you have a driveshaft going to the front too so where would that differential be.....on the driverside.
I think they were just using something already basically 'designed' and fit it into the package they had.......just my opinion.

This is right to the basics of the design parameters. Roc has it right. The reason for the offset was to clear the engine for the front drive and still maintain required ground clearance.

It was a theoretical question Roc...I understand that things like the transfer case weren't designed to be mounted on the opposite side, but...what IF they had been? And the front end, etc. I was just wondering if the result would have then been a "lean to the right"...UNTIL, perhaps, the gas tank was filled, and only a driver got in, etc.
I suspect that you were right, and it was just a matter of "That's the way things have been done, so why would we change it?" <g> (See? I AM something of a "modified fan" too! <g>) Allen's right...it goes right to the heart of design theory, and having always been one to question things, and esp. if there's a "Better Way", I had to ask...(and that's what architects are supposed to do! <g>)

And how many months were the military Jeeps supposed to last by design? If I recall the story, it was fewer than 24.

That's probably a big part of it Sam.....but going with Jack's 'architecture', if I was designing it, it would make more sense in my mind (even if it was designed to always have a passenger) to have the weight 'designed in' to the passenger side. That way, with the offset driveline to the left with the weight of the driver, the load would be more centralized.
Now, Tony, see what you started, we're haviing to redesign the whole damn thing!

Yep, I agree, but now it's easier for Jack to stop eating all those peaches and cream. |

can't remember where i read it, i think over on the G503 in a thread.....but you might want to research the Willys MA, or Bantam BRC....
one of those had the exact same set-up as our 2A's transfercase, only that it was 180 degrees to the other side :)

Peaches 'n cream? Me, Sam? (Jealous, are ya? <g>)
Hey Low...there's a story that goes around every once in a while that has to do with how/why our roads are the width they are, or why train rails are a certain distance apart. I'm sure that you've seen it, but to remind ya, it has to do with the width of two horse's asses hooked up to a Roman chariot! Well, same sort of principle applies here, I think. If it was good enough for Bantam, or Willys, or whoever, it probably was good enough for something prior to their use of it, as well. Sigh. Sometimes, re-inventing the wheel is NOT a bad idea! <g> And yeah, Tony...it's all YOUR fault!!!! <g>

Another thought about a "mirror" (opposite) image to the drivetrain would be the clutch, brake, exhaust, steering linkages ect... They could at least put the gas tank under the passanger side.

Gary, they did on right hand drive models :) in one of the links of the LIFE pictures is a right hand drive 2A.... also, this summer Tom Wolboldt told me of a 2A in his home area that has a fuel opening on both sides of the tub, and he said the insert sure looked factory... well a few weeks ago, i came a cross a 1946 CJ2A for sale, and i will be damned if it didn't have a fuel opening on each side of the tub.....
anyone else seen one of these vehicles?
