Can anyone post up a link or thread detailing the clutch actuator removal ? I've tried to search for this after reading into it a bit in the "Weight Loss Sticky thread". Any pluses or minuses to this mod ? I'm installing a Tilton in the coming weeks and shouldn't need it with the clutch release bearing they use, and have read that it's 30-40 lbs!?

 

Anyone ? Keep reading about this mod but having a hard time finding any hard research on the process.

 

onelove,

I had it done for me, so I am not exactly sure how everything was done, other than the accumulator was removed with the lines that ran to it and there was some capping/plugging of outlets involved and new lines/fittings required for the new closed system.

I did this conversion in order to eliminate the over-assisted, vague feel of the OEM clutch set-up which bothered me from day one and it worked great. My tech installed the 993 GT2 slave, corresponding master cylinder and a 993 fork lever, which is a mirror reverse of the 996 lever. It was a fairly involved process, but with great results.

Here is a picture of the old (996) fork and new (993 GT2) slave. You can see the opening where the 996 slave was located to the left. This opening must be sealed. I have the accumulator in a box and it does not seem to be anywhere near 30 Lbs. - going from memory, I think it felt like about 10 lbs - of course it would weigh more with all the fluid in it and the lines, etc.




For comparison - Here is a picture of the 993 GT2 slave (installed) and the 996 slave (sitting on case) that was replaced. Also, the case has to be tapped for the non assisted slave. I believe the holes are there, but they have to be threaded.



Hope this helps.

 

Thank you John D. for the explanation and pics.
My slave has been progressively going out. It will not hold pressure between
engine starts. After the engine is started you feel some assist.
With the Sachs 4100lb pressure plate it feels quite stiff even hard.
My main concern is possible miss shifts, with the intermittent assist,
I don't know exactly how much pressure is being applied. Would this
situation be a candidate for the conversion?

 

Silver,

The conversion I did is quite involved. It would be a lot easier and less expensive to repair your system than to copy my conversion. That said, it depends what you want...if you desire the non-assisted clutch, you should check out the EVO kit for comparison. They recently introduced a kit and it may be easier than what I did and maybe not - I don't know the details as to how it works. The approach my tech took is well designed and lightweight, but a lot of work. I would highly recommend it, but I believe it would cost upwards of 2K to have done. There is considerable increase in pedal force - I got used to it quickly and don't mind it at all, but you have to be OK with that aspect of the conversion. If you are in heavy stop and go traffic every day, it would not be the best choice. I don't have that issue (heavy traffic) and I feel my non-assisted clutch action is perfect. Your signature says "future protomotive"...I spoke to Todd about this after I had it done and he said he has done it the same way, so that may be someone to discuss it with...
