Re: Which bus/motor would you get if you did it over?

looking at the pictures, it appears to be an inline 6 cyl detroit 6/71 or also known as 238hp 2 stroke, that has been adapted to run laying on its side, mostly oil pan/sump and return system mods. Detroit Diesel also used to modify the V6&8 2 cycle engines for use in the pusher transit busses with V drives to lay on their left side so thgat the heads and valve train could be serviced.

Once in a while, I ponder what it might take to convert a common modern engine. I agree, it shouldn't take a whole lot more than oil pan & pickup, and drainback. The drainback might be the difficult part, as I fear the valve guides would suck oil if they were submerged in a pool of it. The mounting should be straight forward crossmembers and brackets made from half inch steel plate. And the SAE bell housing patterns are circular, so the tranny would never know the difference. No more dog house! Yet the radiator could remain up front for best air flow -- the best of both worlds!

Re: Which bus/motor would you get if you did it over?

I think that modern engines are to tall and would be too wide to fit between the frame rails, 33" standard width, but I still havent seen the rulebook that says that you can't build a custom frame. so it becomes an issue of "you pays your money and you take your chances" kind of like a 23 inch roof lift with a monster monobrow.

Yieehah -- that means I'm in like flint!
We have a 1985 Caterpillar 3406 with a 13-speed sitting in the back of the yard where I used to work. The Old Man was keeping it for sentimental reasons -- his first brand new truck -- but I think he outgrew that.
Oh... the brainstorms!

The 3406 Cat/13-speed would be absolutely awesome, probably the finest drivetrain you could ask for. And it would haul that big crate like it was nothing!

AWSOME,

a 400HP+ 3406 with a 13 speed roadranger in Millicent, 100mph uphill and down fully loaded, yup AWSOME by any standards.

then reality kicks in, would believe 70 mph loaded and 9 mpg, just another 15 minuite project, and you would only need to extend the doghouse about 6 inches rearword and 8 inches taller, just minor modifications for a fabricating master like you.

Re: Which bus/motor would you get if you did it over?


Hey, guys.... Let's clear something up, just so nobody goes out and makes a fool of himself.

A Cat 3406 is a 14-plus liter engine and it measures on the order of twice the size of our bus engines. Installing such a beast in a bus... would fall in the category of putting a car engine in a motorcycle. Been done, but definitely not a beginner's project.

Re: Which bus/motor would you get if you did it over?

I was researching engines before buying our bus, & the good things I read about the DT466 made me decide that was the best choice, so far I haven't been sorry about my choice, for one thing it's wet sleeve!!!!!

and just to add fuel to the fire a 3406 is one of cat's smaller engines, it's available as a v8, 3408 or V12, 3412 in industrial versions.
