Unloaded a heavy beverage load this morning, unhooked, hooked back up when empty, brought the empty here. Now I can't get the jaws to release and beating on the adjustment bolt isn't working either. It looks like one of the jaws bent somehow.
I've been noticing it's been getting harder to pull the release arm but I thought it was just me getting weaker from being sedentary compared to my previous jobs.
How does this happen?

Definitely bent. Have you tried setting the trailer brakes and putting the tractor in reverse against the kingpin before setting the tractor brakes?

Got it out with a pry bar and some patience. Definitely needs a rebuild and I'll be down for a day. Fortunately it's just the jaws and shims and I should be up and running again soon.

My fifth wheel saga continues.
The rebuild did not last and it seems I lost some parts going through the mountains on I-26.
Handle won't pull. One of the pneumatic cylinders seems to have lost what was holding it on.hope not dumb twucker Thanks this. -
