That little plastic spacer thingy behind the clutch pedal....

I have a question for you guys, I have an 06 Unlimited with the 6 Speed Manual, and a couple of months back, the plastic cylinder spacer thingy that is on the back side of the clutch pedal on the shaft that goes into the firewall exploded on me. (Pushed too hard on the clutch pedal while I got into my Jeep and was situating myself in the seat, kind of dumb, but it happened). And that gave my clutch an extra inch or so of travel down the the floor. I noticed afterward, that everything seemed ok, so I just left it. I then began to notice when I would push the clutch to start my Jeep, that if I pushed the pedal to the area that used to be protected by the spacer, that I would hear a strange whining sound from under the Jeep while it idled, but if I let off the clutch a bit to its normal travel zones, it stopped. Now fast forward a few months later, and although the Jeep has been driving fine, I have noticed that it seems my clutch was getting ready to go, and in fact just went out yesterday (I'll be replacing it this weekend with a Luk kit). Now, all that being said, my questions are this:
What, if any, damage could be caused by that spacer not being there anymore?
Could that have contributed to a very short (In my opinion) lifespan on my clutch? (Jeep only has 70k miles on it, and I've driven manual transmissions all my life, including another TJ and I never had a clutch go out so rapidly on me, so I don't believe it had anything to do with my driving habits, I'm thinking either this spacer or the previous owner)
Does anybody have a part number to replace that part, or would it be easier to fabricate something?

Thanks


Eric

That part is the neutral safety switch.

An ugly Jeep with some stuff.

Yep. Not sure if the extra throw in the pedal caused premature wear of the clutch, but I am surprised that you didn't discover that the rig wouldn't start once you broke the switch unless you used the fuse bypass.

No need to replace it for function unless you like having the clutch safety feature, but you might fab a spacer to limit the clutch throw in case the extra is harmful.

See I thought it might be the neutral safety switch, but it still functions 100% as it should. Doesn't start without the clutch depressed, does with it depressed, and it isn't bypassed. I wonder if I somehow leave enough of it intact that the switch still works. Odd. Thanks for the help.

Bump for the new day....
Does anyone have any insight as to whether or not I might be causing some sort of damage with the extra travel? Or is the general consensus to not worry about it?

Here is an update for everyone. I pulled my transmission and yanked out my old clutch, only to find....that it was perfectly fine. Well, since I had it out and already had a new luk kit in hand, I put it in, replacing the sachs kit that was in there, and then upon reassembly, I found what caused my problems and found what broke! I found that when I mashed down on the clutch that day, I had destroyed not the neutral safety switch, but the plastic washer behind it that keeps your clutch from depressing too far into the master cylinder, and then in the process, I also broke the plunger inside the master cylinder, which eventually bound up causing the slave cylinder to keep the clutch partially depressed, which is why my clutch was slipping! For anyone interested, here is the thread on how I remedied that situation without completely replacing the master cylinder, slave cylinder, and all the tubework as Chrysler expects you to.

Well, I'm 6'4" and at the time weighed 260 lbs, so you do the math. It proved to be an expensive mistake that I won't make again.
