Today were going to take a quick look at the Fulton A-frame Coupler for two and five sixteenth balls part number f44305r0500. Now Fulton covers this coupler with a limited three year warranty. It has a gross trailer capacity of 10,000 pounds. Again its designed to be used with trailer balls that measure two and five sixteenths inches. This coupler comes unfinished so you can paint it or finish to suit whatever needs you have for your trailer. The latch mechanism works by pulling this release trigger on the bottom side of the latch and lifting the handle up.
As you do this the wedge inside our coupler is pulled up and away from our trailer ball releasing it. Now back up at the latch well you see theres a hole here to secure the lock and prevent it from opening while trailering down the road but itll also prevent theft. When you open the latch the hole lines up with the cut outs in the top of the mount so you can re-insert that pin and keep the jaw open while your hooking or unhooking your trailer. Its designed to be used with 50 degree A-frame trailers and it has a cut out and threaded holes for mounting your jack. Now weve got a two and five sixteenth ball with us today so we can show how the coupler works with the ball.
Well pull up our release trigger, open the latch and we can fit our ball into place. The latch closes and the wedge moves down securing the ball. It allows free movement so the trailer will track nicely behind the vehicle but it is captive and wont let the ball out. Well lift up our latch, the wedge moves back 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 f44305r0500..
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.
