A bnut type question

[maria-n-skip]

On e-bay there is currently 1-46,2-48's and 1 - 52 GMC buses for sale. The one that has peaked
my interest is the 48 closest to Montana. Bad engine (just the start I'm sure)

So the question is what are the dimensions of a 6-71? I have a spare L10 that if possible I might
want to put in.

   Probably just dreaming.

   Thanks

Hi folks, don't forget the Scenicruiser for sale in WA.

Skip: The 6-71 in a GM bus will be a left turning engine.

[maria-n-skip]

Jack,

  Can't seem to find it....do you have the link or number?

   Oh my that doesn't make good soap  :0   Thanks Stan

the 3751 has a very tight  engine compartment.  the only way something other than a 6-71 will fit is if it is smaller  or exactly the same size.

there are a host of other issues as well that would preclude most from taking on   a project like that

Tekebird,

   I could go with my J.D. 150 hp. (a little light for what I would want) or go with a JD 210 hp.
but the left hand rotation thing really brings up a quagmire of hurtles. Ag engines are fairly
cheap and easy to work on. My case 501 engine is too big and my cat d333 is really to big.

I seem to always forget about DD engines that do Left hand rotation. I have nothing against
DD but I tend to stick to things I at least know how to rebuild.

Thanks
Skip

Jackhartjr,

  I would have never looked under "Collectibles > Transportation > Buses, Taxi Cabs"

   So I suppose if nobody can find it will it make minn?
  You know you can get it and I will store it for you

A 6-71 is 54"L X 29"W X 39"H and weighs 2190 Lbs. (Estimated)

A 6V71 is 41"L X 39"W X 48"H and weighs 2010 Lbs. (Estimated)

By contrast,
a 6V92 is 41"L X 39"W X 47"H and weighs 1960 Lbs. (Estimated)

A 6V92T is 41"L X 39"W X 52"H and weighs 2005 Lbs (Estimated)

Or,

An 8V71 is 47"L X 39"W X 51"H and weighs 2310 Lbs. (Estimated)

A way to get around the LH rotation problem, you could use a ZF transmission out of a Gillig or a Neoplan Transit.

Just being helpful.

Hi folks, don't forget the Scenicruiser for sale in WA.

Why do they have to have these so far away?

[maria-n-skip]

Green-Hornet,

   What I told "Jackhartjr" applies for you also. Buy it get it here K buck is their price on delivery.
Plus I promise not to take it to WM to scare the tourists with an air horn in the middle of the night.

  Of course before the wind up all the pre buy stuff is advised.

Unfortunately in a 3751/4151, your limiting factors are every direction, Bernhart bus in PA did a repower on a Silversides some time ago...long process and I am sure was into the 25k+ range and had major engineering

Dallas: Does the ZF transmission have the right angle for a bus that old?

[TomC]

The 6-71 and L10 are close in demension, but you'd have to run the L10 with a reverser gear, or switch to a ZF transmission.  The only engine swap I've seen on a 3751 is using a Series 50 with a V730 Allison, and was an extremely tight fit.  Personally, just rebuilt the 6-71 into a turbo with air to air intercooler, you would go from 220hp and 600lb ft to 300hp and 900lb/ft torque-or 50% more torque!  Makes for a good performer.  Good Luck, TomC

[maria-n-skip]

Stan,

    If memory serves ZF makes a couple of diff configs for the 500 series transmissions.(EcoMat)  80 deg left hand and 80 deg right hand.
    Ok I looked it up don't trust my own memory.

Dallas thanks. I printed out the dimensions and put it in my bus book for future reference.

TomC
    That is always a good option. 900 lb/ft is a remarkable amount.

Tekebird
   that is probably where I got the idea to begin with of course I didn't remember the money range. If I remembered the money
   and what I have spent on my bus already.........well I just won't go there
