  HI all;
      The folks at B&B coach got me hooked on buses before they moved
       to LV.   Really helpful and gave me more info than I could digest
       at that time.   Long time ago, but I have a bus today.  (MCI)
                                                Merle.

Gotta love those CLIPPERS. That first one doesn't really look all that bad but then again, do any CLIPPERS look bad? Smiley
Wish I could have one of those too. I would stick a FORD 6.8L V10 in it with and automatic or a CUMMINS with automatic. But that's just me.

In 1984, I was in the US Navy for a grand total of 5 weeks so it hardly qualifies. I wasn't really motivated, out of shape, and had developed a very huge blister on my foot that made walking let alone marching next to impossible. I fell so far behind, I was falling apart and they gave me a separation. I was happy as can be to be out and had nothing but contempt for the military afterward for several years. But as time went by, I gained much respect and appreciation for our troops. They certainly would not have benefited from a 20 year old turd that couldn't do anything right so it all worked for the best.
God Bless our troops and never forget our vets and their families of those who are no longer with us.

Oh yeah-that's going to work well?! I can only imagine the collisions and people freaking out when it goes overhead


Well people were famously freaked-out by escalators when they were first invented. Probably happened with elevators and revolving doors too. People learn to get over their freak quickly enough.

Slightly different topic but kinda related - my Dad used to work for a company that built cranes and parts for oil rigs (spent some time in Texas too), and a few weeks ago I sent him a link to a Youtube video of a bridge-building machine which totally freaked HIM out. Another example of how the Chinese are often way beyond the West in engineering imagination and ambition, and their willingness to back-up that imagination and ambition with money:

I road on a Scenicruiser from basic to ait. Got on about midnight and walked up steps to upper level.Might have been only pass. That's about all I remember. Didn't have interest in busses then. When I was a kid, I remember liking the smell of diesel fumes and when you saw a Greyhound back behind you, it wasn't long till he passed the car you were riding in. Most roads were 2 lane then.

I want to watch the first video of it operating under non controlled conditions. I thought we only  had that type of futuristic designer.

What rpm is it shifting at? Some adjustment can be done at governor weights and springs if all the shifts are at same rpm. If just one or to are too high or !ow, then there is adjustment at the shift spring plugs if they have the stepped p!ugs; otherwise, shift spring/s need tweaked or changed. Trimmers and modulator will effect shift harshness. The 700 series use a governor just like the Hydramatic at400's used in GM cars and trucks in 60 through the 80's, just about twice as large though. Allison sold valve bodies for them set for different shift points or speeds according to engine governor settings. Don't know how much of that stuff is still available.

So I am now thinking it is the transfer pump.

I checked all ECM circuit breakers and I have good power all around.

When I look at the fuel delivery pressure reading on the VMS display while cranking, it's reading zero.

I see fuel come out at the secondary when I crank, but it's possible that it's just not enough pressure for the ECM to run the injectors.

If I had a way to put 20psi or so of fuel to the inlet side of the secondary I could confirm this. My last test involved filling the bowl on the Davco and leaving the upper cap loose while I cranked. There's enough fuel in that bowl to get the engine running and yet it is not firing. I see the fuel level in the bowl lowering, but very slowly; the bowl holds maybe a quart, and in perhaps 20 seconds of cranking about half of that has disappeared, probably right back to the tank via the return.

BTW, I have no way to put air pressure to the tank -- too many openings. But, really, this problem can not be between the tank and the Davco -- there's already enough fuel sitting in that Davco to run the engine. If there was an obstruction or an air leak between the Davco and the tank, it should run fine until the Davco empties, and then and only then should it quit. That's not what's happening here.

Anyone have a line on a rebuilt fuel pump for an 8V92?

The HT740 that was installed behind my Cat 3406B is what they call a soft shift. The way it shifts is-1st gear is all torque converter, then to 2nd still in torque converter, then the torque converter locks up in 2nd. When it shifts to 3rd the torque converter unlocks during shifting then locks up again once it is in 3rd. Does the same from 3rd to 4th. I also have a manual switch to lock up the torque converter if I want continuous lockup from 1st. It shifts very smoothly. If your transmission is shifting at too low an RPM, maybe a simple adjustment on the throttle modulator is all that's needed. The modulator should be in full open position at full throttle. Good Luck, TomC
