Re: Raw Water pump unscrewing pulley wheel

It looks like a Nyloc nut so it's probably a RH nut so turn it C-clockwise. LH nuts usually have a notch in the hex of the nuts, so check first.

You are right. Turning it counter clock will loosen the screw.

Thanx for your help

Right hand threads, " lefty loosy, righty tighty."
Facing the work.
The opposite for left hand threads.😉
