Today were going to review part number fhdpw340300. This is the Fulton Fold Away Coupler hinge kit for three inch by four inch trailer tongues. It is a weld on application. This hinge kit will let you create up to a 48 inch fold away tongue for your trailer so that your trailer can even be stored in the smallest garage. It is designed to be used with achewaters our standard couplers. This is a weld on installation.
It is made of a sturdy steel construction. It does have a raw finish. The pivot bolt, which is this right here, and the pivot pin and clip are included. Now this hinge kit is not for use on aluminum trailer frames. The part is made in the USA.
I mentioned this is for a three inch by four inch trailer tongue. Basically the measurement would be three inches wide and four inches tall. This part does have a five year limited warranty. Basically the way you would unlatch it is you would just pull the clip, pull the pin out. Now while this is on your trailer your tongue will fold away to the side of the trailer.
Now Fulton does recommend when installing this male casting which is the part that has the center casting right here that this should be attached to the stationary part of the trailer tongue. This part here, the female casting part with the arms on both ends, that should be installed on the fold away section of the tongue. It can be mounted this way or 180 degrees to fold this way. They do recommend that you should always install this male casting to the stationary part of the trailer. Now just put your pin back, secure it with the clip and youre ready to go.
Now the capacity on this is rated up to 7,500 pounds. The actually capacity will vary depending on the pivot length of your fold away tongue. Basically when I say pivot length what that would be is where your coupler is you would measure from the center line of the coupler ball to the furthest pivot hole from the coupler which will be this one right here. That measurement will determine the weight capacity of this hinge kit. If you use the maximum fold away portion that you can use on this would be 48 inches. If it measures 48 inches from the center of the coupler ball to this furthest pivot point then that would give you a weight rating or capacity of 4,000 pounds. The minimum would be is if you measured your pivot length and it was 27 inches then that would give you your maximum weight capacity of 7,500 pounds. The best thing to do would be to go to the product page for this part number. Youll see at the bottom of the page well have a chart listed. That chart will list whatever the measurement of your pivot length would be. It would should you what the weight capacity would be for the hinge kit at that length. Again this is covered with a five year limited warranty. Again that should do it for review on part number fhdpw340300.
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.
