Default 17 Pathfinder oil pump.

I am working on a 2017 Pathfinder 3.5 VQ35DD. Upon disassembly, I realized the Gear that turns the bottom mounted oil pump is only held in place on the crankshaft by the torque of the main pulley bolt, against the timing gear, then against the oil pump gear. No keyway, no pins etc. Can this possibly be right? 2 slick surfaces pressed together with a bolt to turn a gear? Meaning if the bolt was the least bit loose, the oil pump would not turn. I can find no info on this, the parts diagrams do not even show that gear or chain that drives the oil pump. I am perplexed. Thank you for any info.
