I can confirm the bump head is a left hand thread. Turn CCW to undo it. Could be seized with rust in the thread.
Hi CM,
Thanks
Shouldn't that be turn clockwise to undo it. as it's a left hand thread.?
I was out at Bunnings and saw replacement head and knob in plastic bubble pack. It shows OFF and arrow pointing anticlockwise....
Meaning that the thread is right hand thread..
It's confusing...........
I think this is why people overtighten them, AND as they are bump knobs, bumping on the ground wears away the arrow.... and confuses the matter. I couldn't find an answer on product descriptions.
cheers.... I'll have a wine and think about it.
