DodgeFan01 Posted March 16, 2010 Share Posted March 16, 2010 Hey guys, I have an 88 2wd 2.5 manche and I am looking to replace the clutch master cylinder. I have seen a lot of guys on here replace them with newer year models which require new mounting holes. Is there an advantage to replacing with a newer year one? I really don't feel like having to do much modification, I just want my truck running again, but I will go through the trouble if there is something to be gained. Thanks for your time.

HellCreek Posted March 16, 2010 Share Posted March 16, 2010 Hi, Adam, You will be amazed at the difference a dual diaphragm booster and newer master cylinder will make. Yes, it is worth the trouble. By the way, I used the same mounting holes as my old booster. Tom Link to comment Share on other sites More sharing options...

I'm glad you pointed that out because I was gonna add to what Tom posted. :doh: Link to comment Share on other sites More sharing options...
gambit4000s Posted March 16, 2010 Share Posted March 16, 2010 There does not appear to be any advantage to upgrading the clutch M/C, if you have an internal style clutch slave, I would swap to an external style if it failed. A simple replacement and fluid change/bleed is about as far as you can/need to go. Link to comment Share on other sites More sharing options...

Thanks Gambit, I just know that I've seen a few guys put one from newer jeeps on their manches and didn't know if there was a reason or if it's just because our cmcs are hard to come by. I think my jeep still has the internal slave, although it's been 7 or 8 years since I've been in there. My jeep came with(and still has) the four speed pos, however I picked up a 5 speed(I believe it's an Ax5) which will be going in soon so if it would be to my advantage to do an external swap on the slave, that is something I'll have to look into doing. Thanks. Adam :cheers: Link to comment Share on other sites More sharing options...
Eagle Posted March 17, 2010 Share Posted March 17, 2010 The only reason I can think of for changing is that IF you are changing from an internal slave to a 94+ external slave, when you buy the 94+ parts the new master, slave and connecting line come all together as an assembly, pre-filled and pre-bled. As to functionality, I seriously doubt there is any difference. Link to comment Share on other sites More sharing options...
