Road master Falcon linchpin issue

[Sursavage]

Hi everyone. We have a 2017 Thor Windsport 31s. We bought it used in 2018. Not too many issues except the hydraulic pump on the leveling system went out. Extended warranty paid for repair.
However in hooking up the Jeep Patriot with Roadmaster towing system the small linchpin that hooks into large towing pin came loose from the ring that locks it down. Can’t get the ring back onto the small linchpin. It’s too hard to pull apart.
Anyone have ideas? You can tell we are not handy.
Thanks Mary

You need tools, screwdriver and vicegrips.
Or tie it on with string or better, use a viptie, then get a new one at any hardware store.
