Clutch pedal too soft/no feel? Remove the helper spring!

Paul_S · 11-07-2011, 03:59 PM

What a fantastic mod! I've just done mine tonight by torch light!

Here is my DIY write up with full pictures

Did mine today. Had a bit of trouble pulling the pin out after I got the retainer off. Ended up scaring the pin from the pliers and had to take the grinding wheel to the pin to smooth it back out in order to get it back into place. The feel is much better to thought.

If you take a look at my guide (the link is in the post above yours) you'll see you can use a screwdriver to lever the spring assembly up - that way you take the pressure off the pin and it slides out easily.

I know it's a bit late for you but I hope that helps someone else.

It took quite a bit of googling to find this thread, but I'm glad I did!

First off, I want to say many thanks to the posters in this thread that have done the legwork and research to figure out the characteristics of the stock spring. It appears the dimensions are still the same for my 2012 application.

Unfortunately, it appears I missed the boat by a few weeks (months?). I recently bought a G37 6mt sedan. Only had it for a few days, but can't get over how vague the clutch is. Removed the spring which resulted in much better feel. Given that it's a new car, i'm not to thrilled with leaving it out altogether. So, to remedy the issue and save a few bucks, I started a group buy over at the myg37.com site - For Sale Group Buy - Clutch Pedal Assist Spring for 6MT - MyG37

Just did mine today and wow, what a difference. Great low priced mod that really works.

Thanks!

did you bench bleed it or dry install?

Jsolo · 12-24-2011, 01:28 PM

^^Did you bench bleed the master? Did the clutch behave like this before it broke/wore out, before the repairs? If it's a completely dry system, you need to thoroughly bleed it.

Jsolo · 12-30-2011, 07:13 PM

^^Next time you guys use this procedure, snap a pic. I'm having a hard time visualizing. I just pressed the pedal all the way to the floor and was able to easily get the bottom pin in.

ronaldr911 · 12-31-2011, 10:04 AM

^ Dont think I'll be taking the spring back out again - but basically the pin felt too big for the hole (thats what she said). So I had to force it a bit by putting one side of the vice grip on the back of the pin and the other side on the hosing for the spring and squeezing it in there.

UD` · 12-31-2011, 03:46 PM

Just finished replacing the spring. Big thanks to Vaughanabe13 for his DIY. It helped a lot.

I must say that this is the best mod ever. Nissan should use this spring standard on the 370Z.

Jsolo · 01-01-2012, 10:55 PM

I do wonder why they went with such a stiff spring. Maybe too many complaining that the clutch requires too much effort.

ronaldr911 · 01-02-2012, 06:50 AM

Seems to require less effort almost - i notice the difference when the clutch is traveling back up, it does not kick and push its way up and you just have to guide it gently back up (feeling the points that it engages) rather than fighting to keep it down and from springing back up so quickly. Its easier to drive than the stock... no idea why they went w/ such a stiff spring.

I did mine months ago and would never think about going back. That being said, have any of you gone to the dealer for service with that spring in? did they notice or say anything about it
