Has anybody used a 2-71 Detroit gen set in a bus. I realize its going to be loud and obnoxious. What is the consensus? |

Years ago when I was the Port Captain for a marine constuctin company, we moved all of our Tugs,barges ETC from Alaska to Santa Barbara.
We had a brand new crew boat LIVE ABOARD with a 2-71 Detroit gen set. On the third trip into the harbor the harbor master informed me that the people living in TOWN were complaining of the noise of the generator and told me not to run it while docked here OR dont allow it to come in here!!!
I put aboard a small gas generator for just a few lights at night, that satified the harbor master |

Have you seen one of those units? You may want to consider the dimensions and weight before buying one. You would have one of the largest generators ever in a bus.
Consider the size of a 6/71 in a GM coach. Now imagine two cylinders lopped off the end of the engine. Also imagine 2500 lbs of generator and engine. By the time an engine mount is built around it, it'll be heavy.
Not to further pee on your parade, but the DD gensets are not wired for your needs. Unless you have something special located, most of the 2/71s are railroad reefer takeouts and are 3 phase.
Complicated to say the least.
The consensus is: not a good idea.
Unless you have special needs, find an 8 or 10KW Japenese powered diesel genset...Kubota, Mitsubishi (not Chinese), or some such item. They are a little pricy, but worth the effort. You don't want a generator that isn't ready to go whenever you want. Check with Wrico or Powertech.

The one that I'm interested can be wired for 1 leg of 120 single phase and weighs in at 2200 lbs on skids. The dimensions are big but I can get it to fit. I'm most worried about noise and vibration. Those are the points I'm interested in. I have the mechanics of it figured out. A 74db muffler is available for them from my research. |

QM,
JR is exactly right!
I would suggest you look in the archives, as these have been discussed adnauseum!
Yes, you can run one leg to ground and get 120V single phase.
No, a 74db muffler won't do a thing for the noise that comes off the engine. These run 1200 RPM, and go clack clack clack.
They are durable as heck, and cheap for a reason!

And you will only have one third of the rated generators capacity when connecting it for 120 volt output. In other words, de-rate it by 66%!

Ned,
Why not a 3-53?
2-71 = 68HP
3-53 = 101 HP
2-71 = 960 lbs
3-53 = 965 lbs
2-71 = 32L x 27W x 41h
3-53 = 33L x 27W x 35h
2-71 = 2000rpm
3-53 = 2800rpm |

Obviously you haven't ever had to listen to a -53 series scream. They give definition to a screaming jimmy!
Which goes back to the original question of the practicality of a DD 2-stroke power plant.
Outside of the loud exhaust and engine sound and the weight of the unit, 2-strokes are not known for being economical fuel users.
My step-father used DD 2-strokes as much as possible in his marine applications. Not because he liked them better than Cat, Cummins, or any of the others out there. He used them because a -71 series was a -71 series whether it had 2 cylinders or 16.
He only needed one set of injectors that would fit everything on board. Fuel and oil filters were the same. Governor and pump parts were the same. Pistons, liners, rings, and gaskets were the same. Plus, any place you went in Alaska you could find what you needed to fix a DD.
Unless you really want to tick someone off, I would definitely leave the 2-71 for someone else.

Oh yes I have, and they are noisy. I have had a few vehicles with 53's in them. One was a 1955 IH Skoolie that we turned into a 4WD using the running gear from an old Utility Company truck and added a 6V53T power plant.
I also had a 1962 Chevy 3/4 ton pickup with a 3-53, later a 3-53T.
A friend had a mil. surplus Gamma-Goat with an Aluminum 3-53.
Loud? yes, but not as loud as some of the aftermarket exhaust systems I hear going up and down the road everyday.
(By the way, the pickup had a 609 Road Ranger for a transmission and would achieve 23mpg empty and 18 when pulling a fully loaded 30' hay trailer.
Much better than any Chev/GMC product I've ever had with a gas motor.)

Sounds like a winter project Put the 3/53 or 3/71 in the van. Then it might not quit and "charley" would not have to ride the HONDA back.
Then i could join the hot rod group on the mck board.
