This time I'm gonna print out the answers -- with all the info my '06 manual it doesn't have a listing of the GVWR nor by axel -- can some one pass these along to me again. Also I don't suppose they had such a thing as a GCVWR back then (to include things towed -- brake and drive train limits I'd guess) but what might that be also for he 4106. If it matters any I have #1750 4106 (is it a bus nut sign when we have out vin numbers memorized?) -- Thanks Jerry

front axel, 12,000 lbs,
rear axel, 20,000 lbs.

I had to convince the DMV that there wasn't a listed GVW given in 1964.

AS you have dual axles , with 4 tires on each you could load the rear to 20,000 on each and the front to the usual 12.000.

The truckers road books frequently list the state limits .

The BIG no no is running a 20,000 lb BRIDGE with 52,000 coach, Lots a $$$$$ if you get caught.

IIRC, dual axles less than 10' apart, centerline-to-centerline, have a limit of 34,000 lbs. Over 10', it's 20,000 lbs. per axle.

That translates to 46,000 for the Scenic (34 + 12)

hmmm.
what do they (greyhound / gm) use for passenger estimates when building these things?

off the assembly line she weighed (empty)
front axle 8053 lbs
rear axles 21,480 lbs
total 29,533 lbs.

add to that
fuel (180 gal @ 7.3 lbs / gal = 1314 lbs
coolant (23 gal @ 8.33 lbs / gal = 192 lbs
47 pass @ 200 lbs (a bit less than the average 75th percentile average weight) / per person = 9400 lbs

29533 + 1314 + 192 + 9400 = 40459

seems awfully close to the weight limit you mention, *especially* when we haven't even begun to talk cargo. (345 cubic feet in the bays, + 190 cu ft in the package racks)

not saying your numbers are wrong, just trying to clear things up in my head :-)
thanks,

Well, in 1953 the average American did not weigh 200+ lbs! More like 150.

We also need to decide if we are talking about the vehicle weight bearing capacity (52,000lbs) or what the road laws allow (46,000).

I have a friend who is a blacksmith who has carried all of his tools & stock North & South following the race circuit for more than 20 seasons in his 4104. The '04 would be 20,000 & 12,000 = 32,000 lbs by axle capacity. He boasted that his '04 weighs over 49,000# and he has never had any sort of chassis failure!

Try that with a yellow schoolie!

Tradionally, buses were never weighed! When I was a Kansas road cop with portable scales, one of our first drilled in instructions was: NEVER stop and weigh a bus or RV, we waved them by the fixed scales as well (Imagine deciding who the passengers were that had to be off loaded to become legal).. I know my 4905 conversion was overweight by legal definition. It was all the wifes fault, darned dishwasher, washing machine, dryer, etc, etc.

Kevin -

Back in the mid-'60s, I had to pick up a couple of relatives at the San Jose, CA Greyhound depot. They arrived on a packed NB LA > SF Scenicruiser, and when we went to the side of the bus to claim their luggage, I was amazed to see four 8V71s sitting on pallets in the baggage bins, with luggage stuffed all around them. I asked the driver about it, and he said he saw them often being shipped from one maintenance facility to another, but only in the Scenics and Buffalos, as their bins were tall enough for the engines to fit.

I've often wondered what these things would have tipped the scales at, loaded like this. . . after all, an 8V71 is around what, 2200 lbs?

Feel like crunching these numbers?? :-)

I don't know what a 8V71 weighs, but when I put one on my trailer, the trailer acted like it weighed more than my Super M Farmall. I think they must weigh a lot more than 2200#. I can't imagine hauling 4 of them in the bays!

Legal limits are there to give the road engineers something to design to. Almost any farmer can tell you that he has doubled the mfg load rating without killing his truck. But that does not mean it is safe to do so.

Like FF said, it cost money to move & stop excess weight.

i've heard a lot abotu the "4 8v-71's in the bays of a scenicruiser" thing, including talking to a driver that hauled 'em.

according to detroit the engine weighs 2345.
call it 2400 in "shipable trim" i.e. palletized, etc.

so there's another 9600 lbs...

yeah,
her weight-off-the-line was 29,533 empty, and i'm trying to stay under that. (probably won't make it, but i'm going to try :-))

i pulled out 37 of the seats and the stock ac pump, so i have about 5000 lbs of stuff i can add in. for the most part i'm running a really open floor plan, so that'll help. :-)

i'm pulling the 8v-71 and the 4 speed spicer out and putting in a series 60 (14L) and a 10 speed eaton autoshift, but i'm not sure what the weight change will be there.

i still have to weigh all the stuff i pulled out of the bay under the factory bathroom, (the steel tanks, etc) since it won't be going back in.
*sigh*

getting ready to pull all the roof panels and insulation out to sprayfoam it...

Down through history....

buses have had pretty much the same horsepower in them as the trucks, and had pretty much the same brakes underneath.

Bus drivers, in carrying a supply of witnesses onboard, moderated their bad behaviour on the road, had to drive smoothly, staying out of the kind of trouble that a truck driver can get into, since no one was screaming in his ear and complaining to management as he pulls wild stunts.

And a bus driver feels downright naked, plainly right out front in the potential crash, the truck driver can think he will hide behind the hood.

Add in that buses regularly and religiously see the mechanic, and that trucks are more likely not to....

Buses, loaded to the gills, kept up with traffic better than trucks and stayed out of trouble for some fairly accidental reasons?

Buses are overloaded. yesterday, today and tomorrow.

Now, whether the liability of personally running overloaded will look good in the courthouse, if the wrong thing happens.....

Keep those insurance coverages high and the premiums paid!

happy coaching!

Well stated. As a former member of the bus driver's community,
we always considered ourselves above the "truck driver" status;
We carried the world's most precious cargo: Human lives. And
we tried to do so, in the most perfect manner.
