it could get damaged from forgetting to take pto out, then driving, 10 rpm is the max usually.
If your in reverse then hit something it could get damaged.
If u joints are worn
IN my case who ever put installed previously didnt have correct backlash setting. they had only 4 gaskets between pto and trans. U need a kit that comes with a spacer that is 3/4" and 4 gaskets then your good that the reason my bearing from pto ended up in trans
THANKS GUYS ON THE CONGRATS
THIS MORNING BLEW TWO hydrolic lines then a back tire on Grapple truck. At end of day my trailer tire on bobcat trailer blew. Did a job right after the contractors were there I guess. Looks like they dropped a box of nails in the drive way, seen nails as i walked up the drive to get paid or get back the $700 I just spent on tires and hoses
