Attached is what happened to my '54 rare power steering water pump 2-groove pulley. First day I drove the car!! Anyway, no other damage except wallet for a roll back charge for 100+ miles.
Micrometer indicates 0.063" or 1/16" thick on the stock Hudson pulleys; extremely thin. The pulley next to the broken pulley is the stock single groove pulley; same thickness.
Am replacing this with the pulley in the 2nd photo. It is larger in diameter but no interference and belts line up as per the '54. Will turn things slower but will try anyway. Do not know what car it came from. The thickness of the new pulley is 3/16"--three times thicker~~~
Purpose of this post: perhaps you should carry a spare pulley. But suppose after 60 years fatigue is inevitable. I have no use for the single groove pulley--PM.
Moved to "Hudson" sub-forum.
235 cu in Chevrolets (circa 1955) used a thin-faced pulley with a reinforcement plate added inside that in effect made the face (what cratered on yours) thicker. Resembles yours a lot, sez me.
This is mot a whole lot of help right now, but you may find another pulley, and maybe someone has seen something like the Chevy reinforcement plate on a Hudson pulley.
Good luck.
Chevrolet water pump pulley.
have another pulley but don't know what it was from; no interference; larger tho~~~ 3/16 thick.
This applies to all cars from 1932 onwards. It pays to check regularly that there is no squeaking or movement when you grip the fan. The main problem with Essex 6's from 1924 to 1931 was the fan blades breaking off, similar to the pulley. Very light construction, and liable to either do serious damage to the radiator top tank, the hood sides, or your face if you happen to be looking at it when it breaks off! Also not unknown for the fan blades to break off on later models as well, so the old "eyeometer" every now and again pays.
RIHARD YOU SAY IT COST $100 FOR THE ROLL BACK TOW AAA MEMBERS GET FREE TOWING I HAVE THE BETTER PLAN IT WILL TOW ME 4 TIMES A YEAR FOR FREE UP TO 100 MILES 1 TIME 300 MILES A GOOD BUY IN MY BOOK
Shouldn't you be posting that under "items for sale"?
Also, and by way of illustration, Model A Fords came with a 2-blade pulley welded from two pieces of thin steel to resemble a nice propeller. Those have a way of deteriorating internally and cracking - they can wind up with their fundamental frequency (in their deterorated state, appearing sound)in the range of the engine vibrations.
Result: Death and violent destruction. They have a way of exiting through the hood or radiator. Happens a lot, especialy on restored cars.
Any time one has a thin fan blade or whatever, be critical of its soundness. Cracks are death.
I recommend looking in the GM parts bins for a replacement pulley in this case.
I bought two of those recently to use on two of my engines. They are about perfect. With a regular waterpump shaft you just need a 1" extension available at any parts store. They are a smidge closer together than the pulley but I dont think it will cause any problems.
