Today were going to take a quick look at the Titan weld on Coupler for two and five sixteenth balls part number t1755000. This is a weld on coupler designed to be used with trailers that have three inch wide tongues. Well take a measurement here of the inside width and well get our three inches. The coupler has an overall length of about nine and half inches. Its finished in a gray primer so you can come back and paint it whatever color youd like to match your trailer. It has a gross trailer weight capacity of 21,000 pounds.
The latch system is a little bit different than on many other trailer couplers. Theres a safety release here that youll have to pull up in order to open the latch. To close it all you have to do is pull it forward. You do want to make sure that the safety is set properly. When the safety is down in place in the slot the latch cant come open until you pull this.
You can also use a coupler lock here to secure it and prevent the safety release from coming up that way youre guaranteed that the trailer cant come uncoupled while youre pulling it down the road or you can prevent theft while its in storage. Now well show you how the system works from underneath. Inside the ball socket area theres a piece of tubular metal here that fits around the back of the ball. Well pull our safety release and open the lever and you can see that piece of metal move back and out of the way. As we pull the latch forward it drops back down into place.
Now weve got a two and five sixteenth ball with us so well show you how it works with the ball. With that piece of steel there we cant get the ball in. Well open the latch and our ball fits into the socket. Now well close the latch and that piece of metal moves forward and fits around the backside of the ball. Now our balls secured and it allows travel for smooth towing behind the vehicle.
Thats it for a quick look at the Titan weld on Coupler for two and five sixteenth balls part number t1755000.
Today on This Old Boat Trailer we are going to rebuild the hydraulic actuator on here and we are going to be using part number 85841, the master cylinder itself, and then we are going to use a master cylinder replacement cap part number A87478, and the cable push rod replacement kit part number 85852, all from Atwood. The first thing we need to do is remove the old master cylinder itself. This is going to require taking off the cap which we have already done. We have disconnected the line back here already and then we can see our factory line, lets disconnect that and then we are just going to undo these four bolts right here. There is probably going to be some leftover brake fluid in there so it will be a good idea to wear some gloves or something. We are going to pull out the back and then underneath there is a little push rod you may want to pull away from it too to help knock it out. 01:09
Today on This Old Trailer we are going to install a brand new coupler using part number 2836AT from Master Lock. This is going to be a three inch wide coupler on it and in between here is going to be three inches wide and it is going to use a two inch ball. The first steps involved are to remove the old coupler. It has been on there for awhile. It is rusted so take a couple of wrenches to it and maybe we will get lucky and we will actually break the bolts and get it to come loose that way. This little stand right here got bent back, probably pinching the coupler, so we are going to take that one apart too. Obviously this is rusted in place so we are going to have to persuade it off. 00:59
Today we are going to show you how to replace a hydraulic coupler. In this case this one is damaged and is going to get replaced by a totally different model. First thing we are going to do is actually drain all the fluid from the master cylinder. And what we are actually going to do is open up one of the wheel cylinders and pump our fluid out and into a holding container. All right we will go to the wheel cylinder now and attach a rubber line to the bleeder valve and get our container ready. What we will do is take the cover off our bleeder valve here and we will go ahead and open it up. Okay, here we just take a rubber hose and just slide it on to the bleeder valve itself. All right and then we will just run the other half of the hose into an empty container here and start draining the fluid out of the master cylinder.
