How to Install the Dutton-Lainson Class II and III Couplers Repair Kit

Today we'll be looking at a repair kit for Dutton-Lainson class 2 and 3 couplers, part number DL13970. We are using coupler DL13835 for demonstration purposes, but it'll also work with DL13897, DL13847, and DL13800. Here's what our coupler repair kit comes with. We have a new handle latch to operate our coupler itself. We have a new ball latch, 2 new springs, a nut, and a plate to hold our nut in place. It's a tool-free installation.

You don't need any tools at all to install this, and the reason you'll need this kit is over time, your ball latch can become worn out and not grab onto your ball on your ball mount very well, causing your trailer to run the risk of popping off your mount on your truck or your tow vehicle. Never a good situation. Sometimes our latches can become damaged, and not latch into place properly either. Now, we clearly have this off of a trailer for demonstration purposes. That way we can show you all the inner workings inside of it and how all the functions operate. More than likely when you're doing this repair it's going to be attached to your trailer, so for safety's sake, make sure you chalk your trailer's wheels before you begin any repair.

That way you don't run the risk of the trailer running over you or causing property damage. We'll begin our repair by first removing our old pieces. We lift up on the latch, flip it over. We'll push down here, back the nut off, set the nut aside, let go, take our plate off, take our small spring off, flip it over, pull off our handle assembly, take our large spring out, take our ball latch out. Take our new assembly here, slide it in, place our spring on, slide our ball latch into place, put the small spring on, our nut catcher. Now throw the nut on.

All right, there should be good. Now we can test the operation and make sure it latches, and it does. It'll wrap around our ball here, securing our trailer to our tow vehicle. The replacement kit even comes with a pin lock to make sure your handle doesn't accidentally release and uncouple your trailer from your truck. All you have to do is just insert that like so, and as you see, you can't open it now, so it's a nice safety measure there that's included with the kit.

Now that our coupler's been repaired, all you have to do is pull the pin, open it up, and we can hook up to our tow vehicle again, and we're ready to hit the road. That completes our look at the Dutton-Lainson coupler repair kit, part number DL13970.
