How not to check tri-power
« on: December 02, 2017, 10:29:27 PM »
I did something really stupid, but I'll give the details in hopes that it keeps someone else from doing the same thing. In my defense, I was home with a bad head cold and decided to go play in the garage.  I'd been meaning to confirm that the tri-power on my '60 Eldo was operating, since I don't really notice a surge under brisk acceleration.  I attached a vacuum pump directly to the vacuum pot, started the car and moved the throttle rod well forward.  Then I applied vacuum.  Guess what!  The front and rear carbs work great!  The engine screamed, at least for the few seconds before I shut it off.  I had forgotten that the front and rear carbs are either full on or off; there is no in-between.   But these few seconds were long enough to pop off the fan belts and actually cut the the generator belt.  Today I got a new gen belt and installed the others.  The engine sounds ok, although there is a fierce vibration, apparently from the water pump pulley wobbles like crazy when the engine is running (but feels solid when the engine is off).  Is it possible that my stupidity resulted in a bent hub/water pump shaft?

David,
  Did you get a Time Slip at the end of your Run?  ;D  I doubt you did any mechanical damage......If something broke, it probably would've happened anyway if you put your foot to the floor, except there was no load on it. Think of it as a "Dyno Run"......

I've done some doozies too. It always makes me feel better typing it in here so that someone else doesn't do the same thing (at least that's what I tell myself anyway)

Agreed. Some days I should not even look at my car, in order to spare it and myself the resultant carnage and embarrassment that sometimes follows. Fortunately the CLC forums then provide a saving lifeline when I do mess up. Clay/Lexi

David,

Actually your test was a great idea and you would have seen the linkage move with the engine off.

I can't see how this would have bent anything but if you need anything I will look through my parts pile for you.

Yes, OH! Yes - been there.
There is consolation in knowing you're not the only one or alone - and that we were all in First Class on the Titanic - LOL.

However, your 60 has the fan hooked to the clutch, right?
Doubt you bent the pump shaft - but you'll find if so when the car bleeds out.
If the fan belt thrashed around and broke it could easily have snagged the fan blades and tweaked the clutch or at least change the pitch on one or more of the fan blades = vibration smoothing out at higher RPM's.

Have, fun,

I took things apart yesterday, and the pump shaft is definitely bent, and there are no vibrations when the engine is running with the pulleys off.  Seems odd that the pump shaft would bend, but the pump was an aftermarket pump installed by a shop in Las Vegas during my ill-fated trip to last year’s GN. They told me it was beefier and higher flow than original, but in tracking down pump options, it appears to be the “Falcon” pump that is sold various places online.  It may well be beefier, but if it’s got cheap guts, that could have facilitated the shaft bending.  I still have the original pump that failed in Vegas; I am going to send it off to Arthur Gould for a rebuild.

May want to investigate a progressive linkage set-up.
