No it doesn't. Just keep the ring spanner on the adjuster nut.This assumes that you hold the locknut still while adjusting the clearance - that wasn't specified. It also assumes that they were torqued properly the last time. Too much assumption for my liking.
It is a locknut and it will tighten back down to exactly the same position whatever is done to the adjuster screw.
If you don't believe me take off your rocker cover and give it a try because you obviously can't visualise what I'm saying. Would it be too much for me to assume that you are capable of removing the rocker cover?
