Video Transcript for Bulldog High-Profile Latch Repair Kit Installation

Today we'll be having a look at the Bulldog high-profile latch repair kit for heavy duty cowl lock couplers, part number BD054200. This kit also features a replacement cap spring, that if you only need that, it can be purchased separately as part number BD500354. This kit works on couplers such as part number BD028386, which used a 2" ball. We have our new latch here, a new clip, a new keeper clip, a new bushing, with 2 keeper washers, and our new spring. The reason we want this replacement latch kit is in case if it ever becomes damaged, we can easily replace it without having to weld on a whole new coupler to our trailer. We have a couple tools here today. A pair of channel lock pliers, and a flat-head screw driver.

This should be all you need to perform this repair. You may notice we have a coupler off to the side here, not actually attached to the trailer, just so it's easier for us to work with and show you how to replace these parts. First step, we'll pull our pin out, like so. Set it aside. Pull our latch back here, pop out this clip with a screw driver. We'll work the latch or the clop on out.

Now you have a couple options when you're replacing this. You can either cut it off and remove it multiple pieces, or you can slowly work it on out like this. We'll set it aside. Now we need to remove our handle. To do that we'll pop off these clip washers, once you have it off, set it aside.

There's a second one of those clip washers underneath. You can get that one off as well. With that off, set it aside. Push your pin off, remove our handle. We can flip it over and remove our spring. Use the screwdriver.

I'll take our spring on out. There's a pocket on both sides of it that it sits in, one there, one right there. We'll push the spring in place, one pocket, and push it down in the other one. Just like that. How we'll flip it over. This is the main reason while you're replacing this here, is in case our handle was to get damaged for some reason and our coupler operation didn't work properly. We'll put our handle in position, put the new pin in, flip it back over. We'll install our two clip washers. Push down on them and they'll clip into place. We have one started. Get it the rest of the way, we'll squeeze this together a little bit so our pin comes our more. We have one started, all the way on. We'll start the other one. With those both fully on now, we can get our new clip in here. Start one side, work it on up. Now when we pull back on it, we can push in our lock there, slide it back in place and our coupler is now secure over our hitch ball. We'll take our clip, push it in. Now our handle's locked position and our couple cannot come undone from our hitch ball.

I know this is a small part, but it makes a big difference when your trailer has it missing. My hitch now pops open as it should when I slide the collar back, and I no longer have to keep track of a screwdriver or pry bar to pop my hitch open. It has greatly simplified the process of dropping my trailer. 600854

Product was as advertised and arrived in normal shipping time. However, for the application this spring is way to light weight which is why it was probably missing when I bought the trailer and it did little if anything to help hold the latch open. Not a great value for the money 579457

Perfect fit for an older hitch. Very strong spring. Works perfectly. Package was lost during shipping and they sent another out quickly. Great customer service. Would definitely recommend this to anyone and will be shopping with them in the future. 573307

Product looks just like the OEM ones. They are painted black and fit perfectly. Great and much cheaper option than purchasing a whole new coupler. They are individually packaged which makes them easy to store and each package has the part number on it so if you work in a shop it makes it easy for the other techs to know what part number to expense out. 572920

The spring works well, it has popped out once or twice, but I found it and put it right back in.

I damaged the spring moving the trailer with a tractor. I didn't even think i could get one but etrailer had it. fast shipping and great service on everything i have purchased from etrailer. I live very far from any city and can get parts faster from etrailer than actually driving to the city and finding out no dealer has in stock what i need. Thank You etrailer 476275
