Pinto Hydraulic clutch
westf27 - 12/7/09 at 04:49 PM

As suggested earlier I could go hydraulic to achieve a more suitable clutch operation.The main objectives are to achieve a reliable and light pedal pressure.It has been suggested to use the Rally Design pull slave cylinder,which looks good but not sure how it works.


The threaded rod I assume is the pull part,the rose jointed end could be an option to power the cylinder,as is the threaded inlet ? .Mounting this to the engine so that it moves with the engine/transmission must be possible ?.Any suggestions ?

i want to have a look into this as my clutch is unbearably heavy at times!

what reservoir would you fit etc?

how would you mount it?

surely you would have to adapt the rose joint end to attach to the clutch release arm somehow.

after digging around,it appears the rose end is the fixing point and the threaded end is attached to the clutch arm

There is a diagram here

how would you do the rose joint end?

i take it the opening on the side is for the clutch fluid the top is the bleed.

would you use a master cylinder like this?

will ring them tomoz and find out.Looks like a good idea though.

Recently fitted one of those on a GTM with a K series engine, used an old mini master cylinder and it works a treat. Sorry for the messy picture but I swapped the ends around and used the rose joint as the anchor point. Rescued attachment slave1.jpg

dingz, how have you secured the unit? can i see a bolt into the chassis at the banjo end?

and i can also see that the fluid inlet is on the block side which is a pain in the ar$e!

how have you got around this?

Here is another shot, there are 2 ports at 90° one is the inlet the other the bleed they are interchangeable so you just need to position/rotate it to suit. I guess you could fit it like that gold one in your picture but you would need some sort of flexible compliance mounting so the alignment is ok. Rescued attachment slave2.jpg

The rose jointed end in your picture attaches to the piston, so should ideally attach to the clutch arm. If you fixed this end to a bracket and the other end to the clutch arm, the entire slave cylinder would move when the clutch was operated which you probably don't want.

Thats why I swapped the ends around, the non rose joint end has a nice half round ball just the job for fitting on the clutch lever. looks almost as though they have been just been assembled the wrong way around. Threads are 5/16" unf
