Keep blowing oring on clutch line at master. Can't find new line or used locally...
1991 yj 4.0 5speed internal slave
Replaced me clutch master (for the second time) and keep loosing pressure where the high pressure line joins clutch master. I removed the roll pin and replaced the rubber o-ring. Put it back together and my clutch felt great for about 3 pumps then the pressure let loose at the o-ring again..
Should I.. Replace the master again? Or the high pressure line (with quick connect in the middle... What is wearing out here? Thx

Reason: Not well represented
This is the third master I have used ... All have been metal. I thnk the problem is the fitting on the line itself. Where the oring it, .. Almost like the roll pin isn't pressing the line in firmly enough, or as if the oring is letting fluid by... And I changed the oring once today to see if it made any difference and it didn't. I'll have a used high pressure line from the wrecker by tomorrow afternoon.. I hope it solves the problem.
So I went to the wrecker near my home that contains the majority of jeeps around here. Not a single clutch line matched mine... Roll pin fitting at master and quick connect near the slave.
My new question is there a yj clutch master that uses a standard threaded brake line style fitting AND has the same hydraulic cc transfer as my clutch master?
This would allow me to just line a solid clutch line from the new clutch master bypassing the quick connect and attaching to the line hanging out of my slave cylinder? Some of the yj tubs I saw at the wrecker has clutch masters that had threaded fittings. I don't know which year they were or whether they were 2.5 or 4 liters.. Or for internal or external slaves... (It was dark .. All I had was my phone for light
Anyways. Today I'm going to buy a slightly thicker oring and see if it holds..
I also never really mentioned.. I did put on maybe about 200 km before the oring failed on the new master.
My pervious master (also metal ) leaked on the engine side, not the plunger side. It could have been leaking from the oring then, but I never looked that closely.. At $50 or whatever it was for the m/s I just went and bought a new one...
I also don't want to change to an external slave right now so that's not an answer for me
It's possible the line is slightly off. The idea of scrapping the push-in line with the roll pin is interesting. Using a metal clutch master, you could thread the hole and place a hose fitting in it, eliminating the stock configuration. Hmmm..
Fill in your Jeep forum profile for your vehicle - Thanks!
I couldn't find a replacement clutch fluid line when ours was leaking. I had a steel braided one made at a local HoseMan shop for about $90. No issues since.
Maybe I wasn't pushing the line into the master far enough before driving in the roll pin. I'll have to pop it apart again and look at the fitting to see if this is possible for if the roll pin to go through the hole when the line in not pushed in far enough.
Can do.much else until the stores around me open tomorrow .
Possibly found a used roll pin style line an hour away from me. Going to grab it tomorrow and try it first.. Then I'm going to go for the threaded master (4.2 setup?) unless someone tells me it won't work . Thx
