The original pulley cracked and fell apart.  Need to replace it, problem is, the original one is 3.5" in depth and EVERYTHING I find on line or at parts stores is under 3".  Of course, my belt won't line up with this application.  Does anyone have an idea where to find or why my pulley is different than every catalog calls for?

there are DOZENS of different water pump pulleys...

can you examine the pieces and see if you can find a part number that was stamped into it..

that will make your search a lot easier..

i am taking that you have the 283 with a short water pump... verses the longer water pump that was installed in trucks starting in 1969...

these are right from the AZ site..


since you have the pulley off the water pump... please use a mirror and write down the casting number off the front of the water pump and post it...  i might be able to find my water pump catalog.. as they all have casting numbers in them for identification..  but you could also go to the parts store and see if they have a catalog so you could reverse cross what the water pump application is.. so you know what the pulley application might be...

please... also.. you might want to start the engine.. and looking down from the side.. see if the crank shaft pulley is running true..  not wobbling..   when the pulleys wobble.. and its usually the crank pulley or damper.. it will either crack the water pump or crack the pulley as the belt tension changes with each rotation of the crank...

Wow... with a very red face, never even looked for a number stamped into the pulley.  On the outer body of the pulley, there is the number 3711 52.

Will look for the other things you mentioned...

I have the 235 inline 6 cyl.  There is a number stamped on the water pump... 2171.  That's all I could find except for the Made in USA (which you don't see much any more).
