Do all water pump pulleys with the 4 bolt pattern have the 4 holes sitting the same distance from the center? |
In seeing your example image I'm changing my advise.
I would figure out the diameter that meets your needs. Then I would go to a local auto parts store with your pulley and measure/compare it to a mechanical fan's bolt pattern. This would tell you if common fans, like say a chevy or ford v8 fan has the same bolt pattern. If they do then you know which ones from places like summit would work.
If its not the same then call summit's tech support line and explain all of these requirements and size specs to see if they can find one to meet your needs. I believe regardless of how common your bolt pattern is, that they will be able to point you to finding a solution.
I still think it would be worth buying a pulley before making one. Though making one would not be a big deal now that I've seen your image above. Figuring the load the pulley needs to deal with is the only issue with making one. Programs like Solidworks can calculate the stress load in that application, and thus tell you how strong the pulley would need to be, and all the thickness specs, etc.
