Re: [AMC-list] Water Pump Noise 232

Well I'm glad it's resolved. Those sort of things seem to happen more
now. Like that exhaust manifold I had, it was simply 1/4" too long,
and that was that. Had to notch the end bolt flanges.

I wonder how much cast iron is on spacecraft? Any at all?

I spoze you could have just driven it until the extra metal WORE off!

AMC made the  block JUST a llittle bit fat and the water pump impeller was JUST a little bit fat.  So there was JUST a little interference between the ends of the blades and the block casting right on one of the bosses for the hold down bolts.  I checked the diameter of my pump and it was .035 inches greater than the diameter of the pump I removed.   These ain't spacecraft.  AMC wasn't NASA and neither was some unknown aftermarket water pump maker.    2 minutes with my Dremel tool cured the problem.   I considered getting another water pump because there is just a little runout on my current pump shaft, but Kragen's wanted $54 for a rebuilt pump.  My Rambler mentality took over and I let Mr. Dremel cure the problem.
