Tightening these is always scary for me. I usually tighten them lightly - and I know thats not a definitive term - and then let it sit and come back to it and hit it a little more. Typically, I still have other work to do on the pump at this point so doing it slowly over a few days is not a big deal.
I'm usually shipping these, so I'm using lock washers too. I usually have the pump on a skid by this point too. Nice to lay the pump back down once I feel its tightened well, and then back up, see if anything shifted or changed under the movement. Then tighten straight up again if needed. I dont like tightening if its not sitting up, seems like a bad idea. Keep repeating up and down placement of the pump until nothing is changing or moving on me.
The vibration in shipping is so horrible on nuts and bolts, vibrating them loose AND the pumps are usually laying down for shipment, which sucks even more. If I wasnt shipping be a whole less worried about getting it right.
