I have a 2005 nissan sentra with a manual transmission, I know when I install a remote start I'll have to bypass the neutral saftey switch on the pedal, but my question is will starting the car without the cluch disengaged hurt the flywheel or clutch in any way? like say, the clutch wearing pre-maturely?

its more of a safety feature to ensure that the car is out of gear when it is started. Personally in my type of car I have had better luck by turning the clutch safety off because then it puts less stress on the crank when starting. So, All in all, Just make sure you never park in gear and you will be more than alright.

Huh? What? This makes no sense whatsoever:

How in the world are you accomplishing this? You have a linear actuator that pulls the clutch in, thus releasing the pressure plate? I am very confused.... last time I checked, the clutch safety is an electronic interlock that completes the starter circuit by using a switch at the released point of the pedal travel.
You take your car out of gear and sit there with the clutch to the floor at a stoplight do you?

Holding the cluch in while it is running is hard on the release bearing.
Bob, do you mean the pilot bearing in the center of the flywheel?
A manual transmission car idling, in neutral, the cluch is just sitting there, hanging out. If anything, it would be hard on the input shaft bearings sitting there turning at low speed...; you may have a problem after 10,000 or so hours. I have never seen a remote start do any damage to a clutch assembly. Be no different than hitting the dash mounted clutch switch bypass button on an older Toyota truck (came like this from the factory, a pushbutton switch on the dash to the left of the steering column.)

Exactly. I was having a problem remembering the name.

I was just getting at the "tuning clutch safety off/less stress on the crank thing". The clutch safety switch is an electrical interlock, keeping you from cranking it in gear essentially by making you push in the clutch, ensuring it is in neutral.
In remote start, you temporarily bypass the clutch safety for cranking purposes with a relay, or a grounding pulse, or a 12V pulse, or by wiring the crank wire to the starter side of the switch. The clutch pedal ain't moving anywhere......

That's just not so. There is no pressure on the thrust bearings when you push the clutch in, or any other bearing for that matter. The pressure plate is attached to the flywheel and is only pushing against that, nothing else.

When you push the clutch in, there is a fork that rides on the outside of the release bearing. You put pressure on it.

"release" "throwout" bearing if rode excessively can lead to premature wear and degredation. (for those reading this thread who dont know, might as well learn something) So always sit at a light in neutral with foot off clutch.

I hear ya Bob.... I hears ya.. Never thought much about the thrust bearing wearing, but does entirely make sense when you think about it.
Should just RPM shift more often :-). Be like driving the old 87 GMC 5 ton with a 366.... whoot!

Yea, i had a hangover this morning and wasn't thinking straight! It would cause pressure on the thrust bearing, tho i have never seen one go bad because of it....

Buy A DSM
See anything happen that you wouldnt imagine happen. :)
But I avoided it with having no neutral switch. And I will ground out on every other manual car i own as well.
