Does anyone have a part number for a duke water pump with a metal impeller?
I don't want one with a plastic impeller as they are known to be inferior. (The plastic impeller often works loose from the shaft and then doesn't do anything.)
It's for an '84. I suspect the pump itself is the same for all years. (The '87-'88 dukes have a different pulley.)
While we're discussing pulleys, what is the best method of removing the pulley from the old pump and installing it on the new pump?
So now I've got a few things to do to this car...
1) Drop the cradle to fix whatever is preventing the clutch release lever from moving. (I suspect the clutch fork isn't positioned in the throwout bearing properly.)
2) Drill out a broken starter bolt which has snapped off in the block.
3) Re & re the timing cover to pound out a dent that is rubbing on the timing gear.
4) Replace the water pump which is dripping coolant out the bottom weep hole.
Will it ever end?

I bought it as a "project" five years ago from a fella who had put all "aero" trim on it including an aero nose and bumper (with twin exhaust cut-outs). He also had just put the engine/tranny back in but couldn't get the clutch to work. He gave up and I bought it. It's been sitting in my yard (unstarted) ever since. I've finally gotten around to working on it (since most of the bugs have now been fixed on my '86 GT).
The duke runs fine in this '84, I've just got to fix the problems that I inherited from the previous owner (most of which are listed in my first post).
I have discovered though that the more I dig into this car, the more I realize that some people (ie. the previous owner) shouldn't be allowed to work on cars!

I don't think there was a problem with plastic impellers on duke water pumps -- just V6's. I think all duke water pumps have a cast metal impeller. You may have to also replace your cam timing gear if the cover was rubbing against it. It's made of phenolic (a fiber resin material), and can't take much abuse.

If that's the case then that's good (for anyone with a duke).

I don't know if you saw This thread, but I posted a couple of images of the dent. Here's one...
You can see the dent's not very big. I'm hoping it was just barely touching the gear.
Yes it will end,when you get you a Toyota or a Honda. I read here somewhere " Welcome to the madness"
Im sorry but that is just ridiculous. I have an 84 Iron Duke and it is running clean as a whistle, you cant even hear the motor at idle, starts up every time and is just as reliable as any honda or toyota. My car runs and drives like a 2000. Its all about how the owner maintains his car.
"welcome to the madness" applies only to the stock V6 2.8 motors.

Now that I find hard to believe! Let me explain...
To track down the "screaming" that turned out to be a dent in the timing cover rubbing the timing gear, I used a mechanic's stethosope. Just for fun I tried placing the metal bar of the stethoscope all over the engine to hear different sounds.
When I placed it on the intake manifold I could hear a loud rapid tick ticking sound. It's a sound that I identify with every duke I've ever heard running. I continued to place the metal rod all around the engine until I finally narrowed down what the heck was making that sound. It was the gol' darn injector in the throttle body. My gawd that sucker is noisy!
Just mine is a auto
