I sussed out the last bits of my manual transmission Master and Clutch slave uograde/replacement.
Long story short - I hate the 'lubed for life/sealed/prebled/unserviceable' shit that you get from the parts stores... Because they are idiotic. No fluid is good forever, and bleeding a system is just not hard.
So I bought a Dorman MC and SC, separately. Intwrwstingly, there is no seperately-available clutch hydraulic line available for the application. However, there are fittings available (-3 JIC and - 4 JIC, as you like) to go in place of the normal barbed fittings which slide into nylon line and roll-pin in place, allowing you to fabricate a nice, massively-overkilled, hydro line for thr system. I'm using -4, because I couldn't find -3 with field-replaceable hose ends (ie, I want to be able to have 6' of line in the back of the jeep and fab a new line in the boonies, if I need to. Not thet I expect to - this hose is good for something like 3000psi, and I'll be sleeving it in heatshield sleeving for heat and abrasion resistance.
Unfortunately, I forgot to order 45deg and 90deg (and maybe a 180deg, to make the final turn into the SC) adapters, so I won't be able to do it this weekend. But I'll spend that time helping my son get ahead of his XJ's overheating issue, by installing a flex fan and spacer in place of the factory clutch fan. Also, will finalize my plans for the (electric) cooling fan bypass circuit... I want the aux fan to run for 5 minutes after he turns the jeep off, so that it will help address the vapor lock issue he is having at present. It's just a good idea, honestly, so I'm going to do it to all of our Jeeps (90 and 97XJs, 94 ZJ, and 05 KJ)
I *may* just lay in a separate circuit, with a coupler for a 1/8NPT thermostatic switch in the upper rad hose, and that controlling a relay separate from the ECM entirely. This would be allowed to activate any time the coolant in the upper hose got above 200, so it would activate on and off as convection flow circulates in the engine after shutdown. I ran my S10 like this after installing a 350 and it worked great. Not sure yet.
