Clutch Spring Removal to Aid in Linear Pressure

[Cueball]

Have you read this entire thread? This didn't just start with the '15 year model.

Yes, and to the best of my reading no one qualified in auto repair has confirmed. Plenty of opinions though from backyard mechanics. One inch of extra play with the spring removed is a lot.

no extra play in mine

When I was still in Fordland (Dearborn), MI, I got to speak to someone responsible for the clutch and transmission design/testing for this car. He was very interested in my feedback about the clutch spring removal and basically said that the spring is there to meet the Global requirements for lower pedal efforts. Never once mentioned anything to worry about. Again, the weight of the pedal itself is not remotely enough to hydraulically actuate the clutch and put any pressure on the TOB.

Did you miss this?

Perhaps.:headbonk:

There was no additional play for me. There is a slight wiggle with the spring just like without it.

There. I have had the car three days and am already taking stuff off of it. Night and day difference.

I'm a qualified tech and I can say that as long as the clutch master cylinder piston doesn't move inside the cylinder bore as a result from removing the spring there's no way the throwout bearing will move towards the pressure plate fingers causing premature bearing wear.

So anyone to confirm that the clutch master cylinder piston indeed doesn't move inside the cylinder bore as a result from removing the spring?

Sorry I had to ask. :cheers:

This is my 2nd manual car, my 1st being a 350zwith a very light pedal. Just removed the spring and the pedal doesn't really feel stiffer to me? Odd but definitely better response on the clutch. No more jerky shifts

Did this last week after having the car for 5 months. Should have done this before leaving the lot. Much, much better. More "feel" for initial bite and the only jerk is what sits in the driver's seat.

My parents just drove my car for about a 20 minute drive with a cold start and no hard driving. When I entered the car to drive to work I noticed the clutch pedal was engaged about 70% of the travel. I lifted the pedal back to normal position. Is the clutch spring suppose to help from that happening?

The spring has been removed for less then 50 miles

WHOA!!!

I gave it another whirl focusing on this piece instead of the spring itself and it was much easier.

I fully depressed the clutch with my left arm, pulled the spring assembly using the piece indicated above until it hit the brake pedal. It still wouldn't come off cleanly at this point so I slowly released the clutch pedal keeping the spring assembly in the palm of my hand. That way, it flies into my palm rather than the into the nearest eye ball.

Thanks!

Looking at this from a mechanical designer's standpoint, it seems to me if one could easily remove that spring from the assembly, then a lighter spring could be installed to experiment with feel. It may be possible to remove slop in the pedal AND get better clutch feel. Simplicity and cost depends on if the spring size is an off the shelf solution or a custom wound size.

That's been discussed a few times before, and a member or two did find and try out a lighter spring and said it worked well, making the clutch more user friendly while also keeping all the free play out of the pedal.

I'm still surprised someone in the aftermarket hasn't come up with a softer replacement spring and made some money on this. Might even be a way to come up with an adjustable spring so the user could dial in the feel he wants.

Cool. I may have to pull mine and measure for replacement. I can shift ok, but not feeling the engagement point is still a bit weird. I've been driving standards for over 30 years and this car is different. Granted, I've driven more European and Japanese cars.
