Well, I thought I’d make a quick, simple upgrade and do this E350 master cylinder swap. What a nightmare. It’s always the “simple fix” that turns into a huge mess.
I got the master cylinder, and the correct adaptors according to this thread:
E350 Master Cylinder Install In YJ!
Those adaptors are wrong, or I have the wrong Master. Not sure. And I ran to 3 different stores to get the adaptors that wound up being wrong. I only got one adaptor originally, figuring I’ll find the other one later. Then when I got home I saw JCs thread above and thought “cool NAPA has them, I’ll be rolling today”. Got to NAPA at 4:05 to discover they closed at 4. Found them at another orielly 10 minutes further up the road. Then to find they didn't fit when I got home.
That’s not the problem. Even with line wrenches, I can’t even get a single line off the master. So I said screw it I’ll unscrew from the prop valve. Nope. Can’t even unscrew them. So then I tried to unscrew the lines leaving the prop valve, nope not happening. So, my line wrenches are just some cheapos from the parts store and they are deflecting. Tomorrow I’m getting another quality set, if that don’t work I will destroy them with vise grips and have to replace the front 2 hard lines, and the hard line running to the rear. I have a local place, Alliance Hose & Fitting, so I’m gonna have to run to them and get them to make new lines to go from this MC to the prop valve and possibly make me a new rear hard line.
I originally thought this was gonna take less than an hour. Before I got frustrated and walked away I decided to put my new head lights in to make me feel like I’d done something at least.
