I've removed the clutch safety switch on both my boxster and 911T.
In its place I installed a simple kill switch. It gives me added securuty as the cars can't be started without flipping the kill switch. It also keeps my girl friend from driving the P cars when I'm not home...

 

agree, it wouldn't be "us" that "forgot" as such.. but my buddy driving me after drinking session is gonna be some chick and chicks dont get to drive it. though girl on girl has its place in the world

more i read your thoughts on it, the less important that mod seems to be. but steve..is this the mod the reduces the pre startup pressure on the thrust bearing?? that would though, make it worthwhile for me. though as blkmagic has said, it's not an issue we hear about daily either. who knows, i'm always thinking on improvements that are just driveway tinkering kind of stuff.

 

I believe there is merit in that it will reduce wear but I personally like having the safety net in place lol.

 

honestly, my complaint is with having to employ the accumulator during startup. those things dont act right, esp when its ambient cold out. but have avoided the slave delete for one reason or another.

 

if theres a thrust bearing issue than you have the wrong clutch in the car for your power. the only failures i have seen are from using the 993? long ear'd thrust bearing like i have in my carbonetics tim broke his during hard shifting. startup wasn't the issue. the new erp uses the shorter ears form a 996t? and hasn't been a breakage issue.

i would hazard a guess even if there is wear on startup you will burn up the clutch before you wear out the bearing

come on out to tn and dive my carbonetics and gt2 slave. its what a clutch should feel like. manly!

 

The thrust bearing I mentioned is in the engine case, generally at least one of the main bearings serves this function. Google DSM crank walk and you'll see what I'm talking about. Supposedly cranking those with heavy clutches depressed and no oil pressure accelerates wear. Not an issue with these cars to my knowledge - I wouldn't disable the switch.

 

no i got no problems i'd just like to avoid em if a simple mod like that'll help.
i'm on a new stock clutch gt2 disc and it may not be manly but i dont use it a whole lot. unlike me, it s a quick in/out lol

i joke about it, but this current clutch could well outlive me as i'm too old to die young


think i'll stay with that then, thanks.

 

When we broke my engine down for rebuild due to ever increasing metal in my oil filter, we discovered that the main source of this was wear on the thrust bearing due to the lack of oil in this area when starting with the clutch depressed. The interconnect switch was disabled about 6 months ago but the damage was already done. None of the Porsche ROW cars have this feature which is driven by US regulations.

 

Pardon my ignorance, but if I remove my helper spring do I have to reinstall the bucket that the helper spring sat in? Seems the reinstall of the bucket may not be needed, but wanted to confirm. Thanks

 

no you do not. you might have a cruise control issue if the safety switch doesn't stay engaged as the spring helps with that. if it does then install the home depot spring into the bucket

 

^ MUCH appreciated my friend. Thanks!

 

man, it';s info like this that makes me want to rethink NOT removing anything helper spring or whatever that puts undue stress on the car just to start it! dang, you have some competent help there john to have isolated the source of the shavings like that!

i've just hit 126750 miles! probably too late for me to worry about it anyway

really looking forward to hearing of the finished rebuild. man thats gonna be something. kudos.

 

That spring is going to have zippo to do with thrust bearing wear. If you want to save a thrust bearing start it in neutral without depressing the clutch.

My cruise switch WAS fine sans spring but now errors. When I have a chance I'm gluing a small pencil eraser to the plunger :P

 

isn't there just some wire that needs to be undone to de-activate the necessity of clutch engagement for startup?

i get that the spring mod is a "feel" thing, nothing more. i'm more ( once again ) of the mind that i'm still cogent enough to remember to ensure my car is in neutral before i turn the key.

i know WHY it exists, but i dont think i need porsches help in preventing me from attempting to start the car while in gear lol

but thx blkmajic i did confuse the two upon reflection! i dont sleep much duh

 

Remove the neutral safety switch and jump a lead across the pins. Car will now start in gear so you have been warned
