JD 790 lower arm attachment

kirbydale · May 23, 2021

I can't find anywhere if this lower 3pt hitch arm's sheared pin is a standard cat 1 pin or something different. The top sheared off and the sway chain came off.

Here's the normal side. I've no idea how to approach this repair without jacking up, removing wheel and seeing how it's put together but am hoping someone can tell me before I make a bunch of trips back/forth to shop/tracsupply/home.

and here's the sheared side

Help me obi-wan. You're my only hope

I should add it appears not only to have snapped off the linchpin but 'opened' a gap during turning, allowed the sway chain to fall off the shaft....only to come back together. Hard to believe but I have no better explanation.

I must add that it has two shafts, one per side. Not one long one.
