My OEM clutch MC is showing signs of leaking around the boot---again!
Happened a number of years ago, causing untold havoc with my electrical system.
Anyway, back then ended up buying a replacement from local Jeep dealer. Didn't pay any attention to bore size, just bought one for an "88 Laredo, 4.0, with Peugeot trans".
Did notice that my pedal has to be on the floor, literally, for the clutch to fully disengage.
I've since installed a Chevy with an NV4500 trans, along with an external slave cylinder with a 7/8 bore; I still need to go to the floor for disengagement.
Now that I need to replace the MC again, I wanted to determine my options, considering fitment and bore size; I'd like to get as close to 7/8" as I can.
I've perused a number of on-line suppliers, and get mixed info on bore size for the '88. I was not aware that more than one size existed.
Some examples of what I've found: Dorman CM39645; 1.063 (1-1/16) and made out of plasic. Dorman CM106439; .813 (13/16). From NAPA, NNC39645; 7.75MM (Huh? that's .305, or less than 5/16). From Kragen, CM113830; .8675 (11/16). From Rockauto, a number of different suppliers with no sizes given, and a couple that duplicate the above info.
Can anyone shed any light on MC bore sizes for the '87-90 XJ?
