this is the end that usually breaks, the only thing holding this from spinning is the little bit of surface area around the bolt. once it spins it loosens the bolt just a little bit and causes the pulley to woble then it breaks off. as you can see ours is one piece.
You really need to have the shafts coated, I assume your using chromoly steel thats been normalizied. If so, you still need to heat treat them, then put a surface hardening coating on them. Because it's steel, it will corrode extremely fast and the 6mm bolts will not be able to hold that load. So you can make new pulleys, and go to 8mm, which I think would be beneficial if you don't harden and coat the shaft. But we also found that the typical seal will not live as well on chromoly unless you can find a PTFE type seal. Another reason for the surface treatment.

we have broke alot of quad rotor whipple blower snouts which caused us to not be able to finnish poker runs, so we decided to design our own. we made them out of better steel, bigger shaft, the end that usually breaks is the pulley side that is bolted on, we made that all one piece so it can never break, then on the other end the stock one is just pressed on with no splines and just a little bit of texture to keep it from spinning, but we have had those spin off the shaft too, so we splined that end so it could never break loose. we also have had the bearings sieze up, so we are using higher rated bearings. here are some pics of ours and the stock one.

wondering with all these great sugestions, and the awareness of whipple "knowing" these items, why they were not done previous .....just a thought.
And I have still seen the quads have problems, even late models as of a few months old for what its worth

thanks, we just had alot of these break and cost us a pokerrun, so we were going to have some made for ourselves, but decided to have a few more made incase anyone else needs any.
I do know that our part will not fail, yes i'm sure that will make it find the next weak link, but maybe we only needed alittle more. they did work some of the time, and I dont like the small bolts for the pulleys or the dowel pins but I wanted to make this an easy bolt on upgrade.
