Today were going to take a quick look at the Bulldog Collar Lock Coupler with high profile latch part number bd028462. Now Bulldog covers this coupler with a limited five year warranty. It has a gross trailer weight capacity of 12,500 pounds. This is a weld on application designed to be directly welded to the tongue of your trailer. Its compatible with three inch wide trailer tongues. Well take a quick inside width measure here and theres your three inches.
The coupler has an overall length of about 16 and a half inches. This coupler uses a collar and hinge jaw system for securing the ball. Included with the jack is a pin that goes through our release lever here. To open the jaw well need to remove that pin. You can also instead of using the pin use a coupler lock sized for this hole that will not only prevent the latch from coming open while youre trailering down the road but it will also help protect your trailer from theft while its being stored.
Now to open the coupler well lift oru latch and as we lift the latch it pulls that collar back. With the collar back our spring loaded hinge jaw can open up. Theres also a lip on our jaw that will hold the collar back open while your hooking or unhooking your trailer. To close it well close our jaw and we can let our collar slide forward. Now weve got a two and five sixteenth ball so we can show you how it works with an actual ball.
Well grab our latch, pull our collar back and the jaw pops open. Fit our ball into palce, close our jaw and our collar will pop back into place. Now the ball is completely captive but it moves freely enough to allow nice tracking of the trailer behind the tow vehicle. Well release it and then we can remove our ball. Thats it for a quick look at the Bulldog Collar Lock Coupler with high profile latch part number bd028462..
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.
