Review of Titan Trailer Coupler T4747220

Today we're going to review part number T4747220. This is the Titan zinc-plated break actuator, with the electric lockout for disc breaks. Has an 8,000-pound weight capacity. Now this hydrolic actuator will syncronize your trailer breaks with your tow vehicle breaks. It does feature the electric reverse lockout. If I swing it around here, you'll see the solonoid valve, right there.

This will let you back up without actuating the trailer breaks. Also has this built-in shield that will help protect that solonoid valve from the elements, and also from getting damaged by running into it. This actuator does have a unique roller design. There's a roller right up here, and one down here. This type of design witll reduce resistance during telescoping of this front part of the actuator.

Helps create a straight-line movement. Made of a sturdy, durable steel construction. It will help resist bending and any jackknife situations. It is a heavy-duty coupler. Has a zinc plating, which will provide corrosion resistance, and it is a bolt-on installation. You can see here, at the bottom, has the holes in it.

What you would do, this channel right here, . This is a 3-inch wide measurement. This fit's designed to fit on the 3-inch-wide channel tongue of your trailer. Then you would just bolt it, using these existing holes, here. They should match up to holes on your trailer.

If they don't, you would need to drill holes, to attach this. Also, it includes this break-away kit, which is included. You can see, this is a steel cable, attached one end to the handle on top of the actuator. The other end is attached to a steel hook. Now this is a safety feature. It is required on trailers with hydrolic breaks. Basically, what you would do, when this is installed on the trailer and you attach it to a hitch ball on a tow vehicle, then you hook your safety chains from the trailer to the tow vehicle, also; what you'll want to do is, right where you hook your safety chains, you want to attach this hook from the break-away kit. What this will do is, in a situation where this would come detached from the hitch ball, normally the safety chains would hold it into place, until you could pull over. What would happen if the safety chains weren't hooked, or if they did come free, what would happen is, this safety cable is a little bit longer than those safety chains; what happens if the safety chains don't work, it would pull this cable, which would activate this handle, move this handle forward, and that would activate a rod which would go into the master cylinder and apply the break pressure to the trailer, and lock up the breaks. By chance, if this come detached, and the safety chains didn't work out, this would come into play, and lock up the breaks, to keep the trailer from running away. Also on top of this actuator, you probably notice, there's this plastic cap that you can just unscrew. That will give you access to the master cylinder to put fluid in, and also to periodically check the fluid level. Now this does also have the lever in front with the ring on it. This is what you would do to open up, to hook up to a hitch ball. Just pull up on that ring, which would unhook it right there. That will allow you to flip open this lever. Then with it open like that, it's ready to attach to a hitch ball. Basically, what happens is, right in here, down in there, there's a wedge that when you activate it, when you put it on the hitch bolt and then push that lever forward, until it locks into place, you'll see in the inside, that wedge will move up against the hitch ball and hold it. I'm going to open it, here. I'm going to show you. I got an example right here of a 2-5/16 hitch ball size that this actuator would fit on. When you attach it, it would slide right up in there. Then with it up in there, you let that lever down, you hear it lock into place. That wedge came down, and it's locked onto that hitch ball, so it's not going to go anywhere. Then when you want to detatch it from the hitch ball, you just lift up on that ring, and then pull that lever. That will move that out of the way, and your hitch ball will come right out. Very simple hookup. The application for this actuator is disc breaks only. Again, I mentioned it fits just the 2-5/16 ball diameter. Does have a capacity of 8,000 pounds, a maximum tongue weight of 100 pounds. Just to show you the underneath, real quick, here's where the hitch ball would attach, right in this section, here. You can't see it, but there's actually a . looks like a shock absorber, but it's an actuator that would be used when this is compressed, to apply the breaks. You see the master cylinder, right here. Again, we mentioned the solonoid valve here, for the electric lockout. This is actually installed in the back of the master cylinder. Then your break line would install into the solonoid valve. Basically, what happens, just briefly, to tell you, on a surge break system, what this is, this section here, will slide on those rollers I mentioned. What happens is, when you apply the breaks in your tow vehicle, . This is hooked to the tow vehicle; decelleration will occur, and the momentum and weight of the trailer will move it toward the rear of the tow vehicle. What happens is, it compresses that, and when it does that, that actuator, which is right down in here, underneath here, it will telescope, and it will apply force to this master cylinder, which in turn, will supply that hydrolic pressure to engage the trailer breaks. This is basically how the breaks would be applied on a surge break system. Again, the selectric reverse lockout, what this will do is, this will allow you to back up without activating your trailer break. If you need to back up with the trailer hooked up, you don't want to go backwards and have the breaks be applied. This reverse lockout basically, what you would do, you'll see it has two wires to it. One wire is a ground; the other is attached to the reverse light circuit on your tow vehicle. Once it's wired up, then when you put the tow vehicle in reverse, it will send an electric current to here, which will then block the break fluid from going to your break lines. That's how it will keep your trailer breaks from being applied, when you go into reverse. To use this electric lockout feature, you do have to have either a 5-pole flat, a 6-way round, or a 7-way wiring harness on your tow vehicle. When you do wire this, the wires, it doesn't matter which one's which; they're both black wires. You just have to hook one to the ground, and one to the reverse light circuit. That should do it for a review of part number T4747220, the Titan zinc-plated break actuator with the electric lockout for disc breaks. .
