Today were going to take a quick look at the Fulton Coupler with hand wheel latch part number f3080317. Fulton covers this coupler with a limited three year warranty. It has a gross trailer capacity of 5,000 pounds and its designed to be mounted to trailer tongues that are two and seven sixteenths inches wide. Its a weld on design so when you mount it to your trailer you want to weld full seams along the length of the coupler and here at the back. This is a hand wheel latch which is a little bit different than the typical trigger latch. To open the latch system youll depress this lever and rotate the hand wheel counter clockwise.
To secure the latch to a ball youll release this and as you tighten this latch will start to ratchet along with the notches in the hand wheel. Ill show you how it works from the underside. Heres the wedge that secures to the back of the ball. Ive depressed the release and as I rotate the knob counter clockwise the wedge drops down and out of the way. With the latch released I can start tightening and it will pull tight against our trailer ball.
Now weve got a two inch trailer ball with us today so we can show you how it works. Slide the ball into place. As you can see weve got it loose and it comes in and out freely. Once you have the coupler sit on the ball as you tighten the latch it pulls the wedge against the ball until you cant get it out. Now you do want to make sure that its tight enough.
That it has a good, snug, secure fit around your ball but you dont want to tighten it up so much that itll bind. Again well depress the latch, rotate the wheel counter clockwise and the wedge will drop down and we can free the ball. Thats it for a quick look at the Fulton Coupler with hand wheel latch part number f30980317.
This Old Boat Trailer: Master Cylinder Installation
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
This Old Trailer: Installation of a Trailer Coupler
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
Replacing A Hydraulic Coupler Demonstration
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.
