Today were going to take a quick look at the Fulton A-frame Coupler for two and five sixteenth balls part number f44314r0303. Fulton covers this coupler with a limited three year warranty. It has a gross trailer capacity of 14,000 pounds. Again its designed to be used with two and five sixteenths inch balls. We're going to take a quick overall length measurement here and we get about 13 inches. The coupler is designed to be used with standard 50 degree A-frame trailer frames.
Theres a cut out here on top for jack with threads on a standard three bolt pattern for securing the jack. Now were going to show how the mechanism works. Right now our latch is closed and our ball would be captive. To release well pull this trigger and flip the latch up. Doing this opens the wedge here at the back to allow the ball to move freely.
When it moves forward the latch comes down and grabs the backside of the ball securing the coupler to the ball. Up on top theres a hole here that you can use for a coupler lock to either prevent theft while the trailer is being stored or to insure that the latch doesnt come undone while trailering down the road. As you tilt the latch up the hole lines up with the cut out here on the mount allowing you to re-insert your coupler lock or pin to hold the coupler open. Now well show you how it works from the underside with an actual two and five sixteenth ball. Well grab our latch and open it up, insert our ball into the socket and let our latch close.
It grabs the back of the ball and allows rotation for smooth tracking behind the vehicle but the ball cant come out. Again well open the latch and we can remove the ball. Thats it for a quick look at the Fulton A-frame Coupler for two and five sixteenth balls part number f44314r0303.
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.
