Video Transcript for Fulton Wedge-Latch Cast Head Coupler Repair Kit Review

Today we'll be having a look at the Fulton Repair Kit for Fulton Wedge-Latch, Cast-Head Couplers. Part number F670801. Now, our coupler repair kit here is a very cost effective and simple solution, letting us replace all the critical moving parts on our coupler assembly that can become worn out or damaged. It's a lot cheaper than replacing your entire coupler assembly, which is typically welded onto your trailer. It saves you time, it saves you money, and it gets you back on the road quickly. Now, this coupler is off of a trailer right now so we can easily flip it over to manipulate and show you what's going on. Now, since this is a brand new couple and the rivet would have to be cut off, we won't be doing that, but we'll explain how everything works.

Right here on the side, you can see a rivet head. If you had an angle grinder or a cut off wheel, you could cut this out, draw your pin out and then that'll free up your pivot point here. That rivet that we removed, that's what our new bolt and nylon lock nut replaces. These are a half inch bolt and a half in nut. Now, we'll open this back up here.

If you see right through here, you can see the end of the roll pin. Once you drive that roll pin out with a center punch and hammer, that frees up your threaded rod assembly from your latch. Your latch assembly, right here, would lift straight up off your coupler, and that will leave you with your ball catch, your threaded rod, and your spring. In order to remove those, you'll take your coupler and flip it over. You would just pull that straight on out. We have your new threaded rod already threaded on.

You want to make sure that your pin hole here is threaded on so that it's horizontal like this, longways. Drop on your new spring, drive it back into the bottom. Flip your coupler back over. Your threaded rod will be sticking up through the coupler. Drop it on like so.

Drive your roll pin on through the threaded rod. Once you have that all the way through, you would secure it where the rivet was with the nut and the bolt right here. Then, you would have a functioning coupler again. That completes our look at the Fulton Repair Kit for Fulton Wedge-Latch, Cast-Head Couplers. Part number F670801.

I normally get local parts but they were all back ordered. etrailer had my part in stock and got It to me right away. I will be using them again.


WoW.....where do I start???? George @ etrailer has been the best to work with.. the part that I ordered keep coming up as back ordered and the wait was LONG.. but nothing to do with etailer cause it was still in production so out of their hands...But I was keep in the loop at all times. Never just dropped cause it was a small order.. George treated me as if I had just spent a Million bucks..not just small amount that I had.. So if your in the market for any Trailer Parts shop etrailer First cause it will be the Last place you will need to shop...
