Hydraulic Clutch Conversion

After wasting time and money on cheap Nissan parts...
I am 99.9% certain now that the master cyl (13/16 bore) and slave cyl from a 1985 Jeep CJ or Scrambler (7/8 bore) will do the trick and allow the use of the stock fork. The slave is at O'Reilly for $18.19 and the master at advance is about $57. Part #s CSA11956 and 39738 respectively.... Have to fab a bracket for the slave and get your flex line figured but no big deal. The push rod will be rather simple 3/8 bolt or all thread cut and rounded at proper length. Just figure out your pedal travel and geometry and it's a done deal. I'll document the new setup with pics...

Here are some new pics of the Jeep parts and a hose I had made. You can have a hose made that will reach all the way but I wanted to eliminate the possiblity of a spongy feel from a long section (32") of hose.

The Cherokee master has the side to side mounting flange and I believe the Scrambler master has the top to bottom style. The Cherokee unit has a different style slave flange than what I used here which is the Scrambler unit that by the way is only $20.00

The mounting detail of the slave unit. I did grind for header clearance on the bottom of the barrel end and for mounting bracket clearance on the inner bolt hole ear. The adjustable actuator rod is just a piece of 3/8 all thread with one end rounded and polished. If you have a really stout pressure plate a grade 8 bolt may be substituted. I also borrowed the adjustable plunger rod from the Nissan unit to expedite the installation.

The master cylinder mounted. Much easier to run the steel line with the new outlet location.

The jeep slave installed. The alignment is not perfect but it functions perfectly. There is a trade off on push rod alignment and bleeder clearance on the starter. If using a later model starter you can roll the slave position in a bit more and have a straight shot on the fork.

Notice the addition of gussets on the bottom of the bracket. While bleeding the system I noticed the bracket was flexing a bit so it received a trip to the welder.
