Video Transcript for Titan Brake Actuator T4842100 Review

Speaker 1: Today we're taking a look at a Titan Adaptor Kit for swing away brake actuators. This unit adapts your Titan swing away actuator for use with a trailer tongue that is three inches by three inches, or three inches by four inches. It works with brake actuators T4839000 and T4839100. For a three inch by three inch trailer frame, you'll need to use two of these adapters. For a three inch by four inch trailer frame, you'll need to use one of the adapters.Installation hardware is included, and when it comes to the measurements of the adapter, we're looking at a thickness of 1 inch. Measuring in this direction, it's about 2 and 15/16 of an inch.

It's almost 3 inches. And edge to edge going in this direction, it gives a measurement of 4 and 1/2 inches. With this part number you get one adapter kit.That's going to do it for today's look at the Titan Adaptor Kit for swing away brake actuators.

One of the bolts escaped from it's wrapper (very thin plastic baggy surrounding it all), but was loose inside the box so no problem. Haven't installed it yet (waiting for the main product to arrive, this was just an adapter, but so far looks fine. 280333

  • Replacing Swing-Away Brake Actuator on 2010 Mastercraft Boat Trailer
    As long as your 2010 Mastercraft Boat Trailer is equipped with a 3 inch x 5 inch tongue and weighs less than 7,500 pounds when loaded the Titan Swing-Away Actuator # T4839100 that you were looking at will work great as a replacement. This particular unit maintains the swinging function you had before for easier storage and the electric reverse lockout lets you reverse the trailer without the brakes engaging. If you happen to have a 3 inch x 3 inch or 3 inch x 4 inch tongue you can actually...

  • Replacement Surge Brake Actuator for Titan Aero 6000 for Disc Brakes
    A Titan Aero 7500 will fit in place of your Titan Aero 6000 but the only one available for disc brakes is the Swing-Away Actuator w/ Electric Lockout # T4839100. This fits a 3" x 5" channel tongue but can fit a 3" x 4" or 3" x 3" with adapter spacers kit # T4842100 or # T4842100 accordingly. If you are looking for more of a traditional actuator then you can use either the 7.5K # 099-175-20 (with 3" distance between bolt holes) or the 8K # T4747220 (with a few different bolt holes).

  • Will the Swing-Away Actuator T4839100 Work On a 2007 Sea Ray 230 Trailer
    The Swing-Away Actuator part # T4839100 that you referenced works with 3" wide x 3" tall, 3" wide x 4" tall, and 3" wide x 5" tall trailer frames. Therefore, if you have one of these three frame sizes then the actuator will work for you. However, if you have either the 3" wide x 3" tall or 3" wide x 4" tall then you will also need the Titan Adapter Kit part # T4842100 (Qty. 2 for 3" wide x 3" tall and Qty. 1 for 3" wide x 4" tall). I think you meant to say that you have an electric lockout,...

  • Replacement Master Cylinder for Atwood Actuating Coupler for Drum Brakes
    For your Atwood Brake Actuator w/ Manual Lockout - Drum Brakes - Black - 2" Ball - Bolt On - 6,000 lbs # AT82543, the master cylinder you need is the Replacement Master Cylinder for Atwood Trailer Brake Actuators - Drum 85841 (which has been discontinued). So you will want to check to see if it is the actual cylinder or just the gasket that needs replaced. Let me know as I'm happy to assist.

  • Recommended Disc Brake Kit For 2013 Magnum Trailer With 3500 lb Axles
    For your 2013 Magnum trailer, I recommend the Titan Disc Brake Kit and Swing-Away Actuator w/ Electric Lockout - Single, 3,500-lb Axle # T4843300. This kit will include everything you need to convert one axle to a braking axle. I recommend using the Bearing Buddy Bearing Protectors - Model 1980A-SS w/ Auto Check - Stainless Steel (Pair) # BB1980A-SS with this assembly, but everything else you need unless you need an adapter for your trailer tongue which is # T4842100. If you have a...

  • Replacing Swing-Away Surge Brake Actuator Master Cylinder Or Complete Actuator That Is Leaking
    You may only need to replace the master cylinder depending on your actuator, but I would need to know the manufacturer and model to see if we have the replacement parts. I've attached a link to all our replacement master cylinders to assist. If you want to replace the actuator, I recommend the Swing-Away Actuator w/ Manual Lockout - Bolt On - Drum - 2" Ball - 7,500 lbs # T4839000. If you have disc brakes we don't currently have an option, so you would need to use a disc brake rated...

  • Replacing Brake Actuating Coupler on Boat Trailer With Folding Tongue
    Although we don't sell frame tubing, I do have a solution that would work for you. Instead of the Titan # T4500600 actuating coupler you looked at, go with their swing-away actuator, part # T4839000. This is essentially the same actuator you were looking at, with the addition of a hinge. For a 3x4 trailer tongue, you'd also need one spacer kit, part # T4842100.

  • Hinge Dimensions of Titan 7500 Swing Away T4839000
    The dimension from the center of the pivot pin hole to center of standard pin hole on the # T4839000 is 3.207 or 3-16/64 inches. This Swing-Away Actuator is designed to fit a 3 by 5 wide channel tongue. If you have a 3 by 3 inch channel tongue or a 3 by 4 inch channel tongue, you can use the Titan adapter spacers # T4842100 to allow this actuator to mount.

  • Can a Fold-Away Trailer Tongue Hinge Kit Work with Hydraulic Surge Brakes
    You can use a fold-away hinge kit with a surge coupler but you will need to replace the hard brake line with a flexible hose like # T0777300 that you have referenced. For fold-away drum brake applications use # T4839000. For a 3 x 4 inch tongue use 2 adapters # T4842100.

  • Availability of a 2 to 3 Foot Fold-Away Trailer Coupler Hinge with Attached Coupler
    If you are needed a coupler and tongue that is already attached to a fold away hinge, we have # T4839000 for hydraulic drum brakes. This coupler will fit a 3x3 tongue using 2 of the spacer # T4842100. The pivot length is 21-1/2 inches long. But if you are looking for a 2 to 3 foot extension to the tongue you have, you will need to have a qualified welder in a machine shop of shop that works on trailers fabricate an extension for you. The work should be professionally done if you go this...

  • Are Adapters Or Conversion Kit Needed For Titan Brake Actuator Folding And A75 Easy Loader Trailer?
    I can't find any information on model number A75, but we can tell if you need any adapters by a simple measurement. If you measure the pole tongue of your trailer and it is 3x5 inches, no adapter is needed for your Titan Swing-Away Actuator w/ Manual Lockout - Bolt On - Drum - 2" Ball - 7,500 lbs # T4839000. If it is 3x3 inches, you will need two adapter spacers # T4842100. If it is 3x4 inches you will need 1 adapter spacer # T4842100.

  • How to Determine if the 7,5K Titan Swing-Away Actuator Will Fit 2005 Ranger Reata Trailer
    Could you send me a picture of the actuator on your 2005 Ranger Reata and any part numbers for the current actuator? I don't know what specific actuator came on your trailer but the Titan Swing-Away Actuator # T4839100 is a bolt-on installation that is compatible with 3" x 5" wide channel tongues. If you have a 3" x 3" tongue you need 2 of the adapter # T4842100 and if you have a 3" x 4" tongue you need 1 of the adapter # T4842100. This actuator does have the electric lockout, fits a...

  • Where to Install Titan Swing-Away Actuator
    The part of the Titan Swing-Away Actuator T4839120 that actually pivots is 21-1/2" long. You can cut off as much of your trailer tongue as you like and since the actuator pitots 21-1/2", that's how much space you will save, minus whatever you have remaining of your trailer tongue that you did NOT cut off. Please keep in mind that for a 3"x4" trailer tongue you will also need a 1" Spacer # T4842100.

  • Parts Needed for Disc Brake Conversion on 2000-lbs Axle
    In order to determine if a disc brake conversion kit is compatible with your trailer, you will need to know what bearings and seals are currently on your hubs. The Kodiak Disc Brake Kit for 2000-lbs Axles # K2HR2D fits on spindles that use an # L44649 inner and outer bearing, as well as an inner grease seal with a 1.500" diameter and an outer seal with a 1.987" diameter. You'll want to pull your old hubs and check your existing bearings for stamped numbers on the back to verify which bearings...
