I appreciate the feedback and understand the advice about heavy grease helping to prevent fretting and failure of the splines. The stripped hub was dry as a bone. Still wondering if anyone has opinion about the small amount of engagement on the pump input shaft. When taken apart after the failure, the 3 inch coupler was 2 inches over the drive shaft and only 1 inch on the pump input shaft. when the drive hub splines gave way, the drive shaft would have been free to move toward the engine and leave very little engagement of coupler to pump shaft. I am trying to better understand what happened so I can hopefully prevent it for happening again. I am probably overthinking it and missing the obvious. The obvious is new hub and shaft coated in neverseize will keep the assembly stack-up in place between the 2 points. Thanks
