Re: The Millicent Chronicles; two foot roof raise, big tailgate


What if you tied your island to one side? I'm putting my prep surface\combination eating bar\gray tank cover running from right side to the middle with a 2 foot path around it on the left (that corresponds to the emergency exit door). It lets the cook stay behind the counter, guests can sit and eat on bar stools facing the back of the bus to chat with the chef. Anybody complains about my cooking, I toss them out the emergency door. If I like them, I open it first.

Re: The Millicent Chronicles; two foot roof raise, big tailgate


That's roughtly what I had in mind in my first paragraph above -- where I talked about putting a bunk or luggage racks on one side of the engine. So far so good.

But access to the engine would require a lot of... tilting and lifting the kitchen counter and other furniture out of the way. And the heat and fumes would still be somewhat forward, definitely still in the living area.

With the engine in the back, access for servicing could be easy -- no restriction on size and shape of dog house. And with dog house removed, we would have 360 degrees access. I like this a lot.

Re: The Millicent Chronicles; two foot roof raise, big tailgate

In the drawbridge concept, you have a raised floor in the cargo area. What if you raised the floor like that, did NOT relocate the rear wheels forward, and put the engine in front of the rears but still in the cargo area (under the raised floor). Or does cargo stretch that far forward? Just need enough driveshaft to move up and down enough to handle suspension travel.

In my Carpenter, there is actually almost 2 feet over the engine before the metal containing the "engine bay". It is the radiator on one side that is full height. With the roof lift you have, I can see being able to clear the top of the motor as long as I was willing to be creative with the radiator.

If you move the rears forward, will you run into issues were it will wag a bit too much? Especially if you attach a trailer?

Re: The Millicent Chronicles; two foot roof raise, big tailgate


Millicent already has the axle quite far forward -- because she is a front engine 40-foot bus. When I talked about relocating the axle, I was talking about factory-built pushers.

But a guy could take a pusher bus and relocate the engine to in front of the axle -- and have a nice draw bridge! Again, he would have to solve the rotation issue.

As for Millicent, if the engine goes in front of the axle, then the engine will be in the living area. The rear fender humps start just a foot or so behind the bathroom. I really like the idea of putting Millicent's engine behind the axle. The radiator would be on one side, just behind the axle, and the intercooler on the other side! The only thing I would lose would be a side storage box.

Re: The Millicent Chronicles; two foot roof raise, big tailgate

Alas, Elliot. If you turn the axle around and mount the engine backwards you will have 4 reverse gears and 1 forward gear. If you could source a v-drive from somewhere you could leave the axle in its original orientation, run a shaft forward, and then back to power the axle. Unfortunately I think most v-drives capable of that kind of service are going to cost some serious dollars. But...you are a trucker and as such I know you know of trucking junk yards. A divorced transfer case is typical in 6wd medium duty trucks. You could turn the t-case around so the input faced backwards and then use the "front" output to drive the rear axle. You would most likely end up with a wonderful low gear for when the going gets really tough, a true neutral to protect the transmission in the event towing, and (the best part in my opinion) you could put the transfer case in "2wd" thus only spinning the "rear" output (which now faces forward) and use that as a power take off for whatever you can conceive.

Re: The Millicent Chronicles; two foot roof raise, big tailgate

If you turn the engine and rear axle around with the engine behind and the axle in "front" you will have 4 reverse and one forward gear. But if you then FLIP the axle so the left side is right and the right side is left, it will fix it. Learned that on an episode of "Junkyard Wars". However, as Elliot pointed out, there might be an issue because the connection into the differential is not centered. It would essentially be running upside down (would make it hard to fill with oil unless you get creative). I have no idea of the strength or issues of a differential running upside down though - anybody else have an idea?

Re: The Millicent Chronicles; two foot roof raise, big tailgate

Strength-wise it will be weaker. There will be some slight issues with thrust on the pinion bearings, but more importantly you will now be running on the coast side of the gears. This is good for about a 30% reduction in strength. Reverse cut gears used in a high pinion situation (as this would end up being) will result in a 30% increase in strength which is why the high pinion Dana 44 in an early Ford pickup is stronger (gearwise anyway) than a GM or Dodge Dana 44.

Of bigger importance is oiling to those already compromised pinion bearings. A person would have to get very creative with a gear oil pump or some sort of a slinger. Basically, the bearings are now above the oil fill level so there is no bath oil on them AND the the ring gear cannot be counted on to sling oil on them because of the pinion's location behind and above the carrier's axis of rotation.

Re: The Millicent Chronicles; two foot roof raise, big tailgate


Yes, perhaps I could have spelled out my thinking, and my question, more clearly. Obviously, if you simply turn the whole drivetrain around, you have simply made a U turn and are now traveling in the opposite direction -- with the head lights at the wrong end.

The diff is of the hypoid type, which is pretty much standard on all modern diffs. It means that the pinion is offset downward. This was a great improvement in early automobiles, because it lowered the drive shaft away from the passengers. A hypoid diff is also quieter than a centered pinion, and there is a mechanical benefit... which escapes me at the moment. (bed time!) But the offset is not nearly so much as on some automobiles.

So we have two questions:
Since the hypoid offset is fairly slight, could we get away with running it up-side-down? Perhaps with correspondingly higher oil level?
How do the factories handle this on pushers? I think I'll simply stop by the local bus barn on my morning bicycle ride tomorrow and look underneath a couple of pushers.

By the way, I took Millicent to that bus barn a few days ago for show'n'tell. They loved it.

V drive? Whoo-boy. Too much hardware!

[Stand by.... Reading new post from Experience....]

Right. When I crawl under a pusher tomorrow, I bet I will find a reversed pumpkin. In which case, the thing to do would be to purchase a pusher rear end from a wrecking yard and bolt it in.

Re: The Millicent Chronicles; two foot roof raise, big tailgate

The mechanical benefit of hypoid gears is strength. One gear is sliding into place as another is sliding out and the overall contact patch is much larger. Of course they have axial thrust to deal with whereas straight cut ring and pinion gears could, in theory, get away with simple ball bearings for radial suppose since there is no axial load.

Take a look, Elliot. I'm a little curious. I think there's a good chance you won't see anything different externally and that the difference might be in the cut of the gearset itself, most likely being reverse cut and having the pinion and ring gear flipped in relation to each other. It's no secret that early pushers had Detroits that spun backwards, but obviously that is not the case in more modern machines so something in the drivetrain is different.

Re: The Millicent Chronicles; two foot roof raise, big tailgate

yes,yes it will beinteresting to know what they do for drive axles in pushers, another option would be to shorten up the driveline as short as possible and then move the rear axle and engine back into the garage, you would have to consider weight and balance on the axles and of course a longer turning radius.
