Replacing A Hydraulic Coupler Demonstration

Demonstration Of Replacing A Hydraulic Coupler

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.

And so to pump this out what we are going to do is actually we are going to use the actual breakaway lever right here to actually do the work for us. All right we will go ahead and put our cap back on. Then we will go ahead and take off our connection to our master cylinder here. When pumping it dry that will keep the fluid from coming out and ruining the paint. All right and then the next thing we will do is just unbolt our coupler. All right next is we are going to do a quick test on our new coupler. Now we are not going to use the same one as before. We are going with a different model. So basically you want to take an inventory of what is going on here. It is going to use two existing bolts already in the frame. We are going to drill the third one back here. So it looks like we are going to have to get rid of this zip tie here. And also we will have to modify our brake line here to wrap around into the back of the coupler itself. All right, with our two bolts then, we will just go ahead and tighten those down.

All right next we are going to go ahead and use a 1/ 2 inch drill bit for our 1/ 2 inch bolts. And we will just use this bit just to mark a hole in steel. All right, from our 1/ 2 inch bit we will go up to a 3/ 8 bit and just work our way up. Next what we are going to do is we are going to hook up the hydraulic line. Just pull out the little dust cap there. And then our line, we are just going to have to manipulate it just a little bit to make the curve. Just as long as you do not put a kink in it you will be okay. Okay, once it stops about an eighth of a turn past, that usually does it. All right, double check your lines. Make any adjustments as necessary. Okay.
