woops! had the intake and exhaust "valves/ports" backwards - thanks for the education! Kind of makes sense if I were to have thought about it a little more - pretty difficult to make jake exhaust brakes (common I believe on these for OTR) work without valves instead of ports (especially the...

Honestly, never had the chance to purposely listen to one (have probably been around a few without knowing it!) - they did not like the turbos? The original design had too close tollerances for "extra's"? Man - get one of these with a turbo or worse (better?) toys and they must have really...

If this is correct, it really is a simple system. Kind of similar to a rotary engine where the rotating "piston(s)" essentially sequentially "pass by" the respective intake and exhaust "ports" in a precise fashion. Pretty neat - no valves at all if I remember correctly. Dave.

True - according to the design basics of the 2-stroke Detroit, I think the blower basically helped "clear" the spent fuel mixture and possibly introduce the fresh mix for the next cycle. I think as the piston is pushed down during the burning of the fuel, the down-traveling piston exposes the...

HMMMM - lets take this a little further - Assuming the conversion to 1600/20's, minimum distance between axle centers would have to be about 5 feet (this is probably farther than the rears center to center, but the fronts have to clear each other in a turn - could always commit to max of...

Or you could always start with a 900 series 5-ton with the wide nose tilt hood. HMMMMM. push tge cab back and insert a "band" between the hood and firewall. HMMMMM. Heck - if you are going to push the cab back, might as well add a second front axle (8x8 anyone!). HMMMMMM.

I think that dropping a Detroit into one of the 5-tons is going to have the same "radiator problems" as the M35A3's with the same "narrow nose" - course you could always jack the cab and put the radiator horizontal like the LVS and HMMVEE (sp?) and Louver the Hood! Take a lot of jacking for the...

Not my field of expertise, but it sure seems that at one time they were putting Detroits in everything - must have been pretty adaptable and fairly reliable for the day to have such a following.

Sadly, rorybellows, you are probably more right than not. I have cought a few online videos of the HEMTT's being abused. Don't get me wrong - I have lit up more than a few of my tires in my many years pushing the pedals. But these were MY tires - smoking the rear 4 tires or seeing just how...

Thanks Guys. Just playing around with ideas for the future if the engine in my old girl is toast. Seems like they put different versions of the 2-stroke in everything until the EPA started looking for things to keep themselves busy. Back then we didn't have to pay to have the roads...

Do we have any Detroit Diesel Gurus on here? Just wondering what the differences might be between an 8V92TA intended for a vehicle drivetrain and an 8V92TTA intended for a dedicated piece of equipment (generator, pump, etc.). I know that there is probably (almost for sure) differences in the...
