Am I missing something here? Im trying to pull off powerhead and getting locked up on something. My brother and I were attempting to manually pull it off. Following OEM manual steps, all nuts and bolts are removed and when we pick up, we get a visual of the shaft ( about 1" total),, but seems to lock up. This week I'll borrow a cherry picker from neighbor to save the labor, but I still feel its locking up on something?!?!??!? Thanks,, Joe
