Is the 348 crank bolt standard thread. not reverse.
Yes, it's right hand threaded (ie, lefty loosey) To remove it, many of us use an impact wrench, although use only as much pressure as needed, and if it doesn't loosen right away, I wouldn't overdo it.
Yep. I just did mine on the 355. 6ft breaker bar and it wouldn't budge an inch. Impact gun and it was off in 2 seconds.
