235 water pump and pully Question

I am sticking a 235 into my Chevy truck. And i know you need a shorter shaft water pump. Now different places sell them, but at a lot higer cost. And the onyl difference is the length of the shaft and the pull. I am able to cut the shaft myself and press the plate on it. But i want to know if anyone knows where i can get that pully? That is the only part that is different. Does anyone know the size of the pully itself, and then i might be able to find one off a different vehicle.

Thank,

there was a discussion on either ChevyTalk or Innliners about this a couple weeks ago. I want to say a 55 pulley will do the trick, but check the archives to be sure.

The short pumps come with the right pulley.
You could also use the cheaper, more available, long pump and just move your radiator about 1/2". It will be better if you water pump goes bad in the middle of nowhere

 

Before short water pumps were available commercially, I put a '58 235 in my '53 Chevy, and pressed the hub back on the shaft to within about 1/4 inch of the pump body and used a pulley from a '63 283, and it lined up fine with the crank groove.

 

Sweet thank you very much. Thats exactly what i was looking for. Do you know if any other years share the same Pulley?

I used a Ford pulley on mine. Find a pulley that has about the same diameter, but isn't as deep as the stock 235 long pulley. You'll have to press the hub back, so when you put the pulley on, it will then line up with the crankshaft pulley. After you've got the pulley lined up, you can cut off the remaining part of the shaft, but leave about a half of an inch to align the fan blade with.

 

I may have one in the garage off of my 235. If you spring for shipping, it's yours for free.

the small block V8 engines used that shorter pulley from somthing like 55-68...

 

Falcon/Comet 144-170 water pump pulley is my favorite. When pressing flange deeper on shaft, pull the plate from the pump & support the shaft-don't push on the housing or it'll bottom the impeller on the plate. Also be sure not to push flange down too far or the fan will hit the harmonic balancer. Check alignment several times during job ...

Found it. Let me know if you want it. I don't have any use for it.
I'd rather give it to someone that's trying to restore a ride rather than have it become part of a Toyota bumper one day...

 

I don't know what year engine you're working on, but be aware that the pump in the picture fits up through '54. In '55, the front of the block was redesigned, and uses a different design pump. The two designs do not interchange.
