My guess is yes. I tried taking mine off by holding the retainer nut and turning the 18mm hose nut with an 18mm flare nut wrench to the left and the craftsman wrench broke. So I'm assuming it must be a left handed thread. Perhaps someone with more experience will know for sure.
The simple answer is left handed threads are the opposite of right handed threads. If you have heard the old adage "Righty tighty, Lefty loosey" left handed threads are the "Lefty tighty, Righty loosey". Left handed threads are used for keeping counter clockwise rotating assemblies from coming loose.
Standard right hand thread.
In plumbing we use BOTH right and left handed threads depeng on the useage Toilet handles for example are left handed threads threaded rod used for clevis hangers and riser clamps are right handed threads
no, threads are right handed.
they are right hand threads
If the grass exits the right side of the deck, then the threads are normal right handed treads. If the grass exits the lefts side of the deck, then the bolts thread are left handed threads.
Standard rh threads
the crank pulley bolt has standard threads.
No
I doubt it.
Judging by the video of someone using the starter to break the bolt loose the threads are regular right handed threads
