What do you mean by right tools? I'm using angled feeler gauges regular socket set and I have a craftsman max access ratchet and socket set I use to tighten the lock nut so I can keep a flat head screw driver while tightening it. I checked the clearance before and after tightening the nut. Thanks for the tip on turning the motor I'll remove them when I do it tomorrow.
Do you mean bend the feeler gauge?
