Rotor screw striped

[scottmandue]

I did a tune up on my 1994 944 N/A a few months ago only to find the tiny screw that holds the rotor in place is a hex screw and the socket is striped. That is to say when I put an allen wench into it it will not grab.
Anyone know of a proceedure to remove the little bugger? it's kind of hard to get to to work on. The car is running okay but I would like to take care of it.

Thanks

I've never delt with that screw, but can you cut a slot in it with a dremel tool and use a regular flat blade screwdriver to remove it?

Remove the dust cover (you do have one, don't you?) and unscrew the 8mm (wrench size)
bolt holding the shaft to the camshaft.
Two options then; replace rotor and shaft or
break off rotor until you can get some vice grips onto the head of the screw.

I can't believe they use that soft brass screw to hold it on. I read somwhere to use a US size allen, but it didn't work. Since it wasn't bad I left it on.

Do what Britwrench said, I had the same problem and all you have to do is remove the dust cover it has a split in it so you can remove it from around the shaft. This will expose the small 8mm bolt that you have to remove. Be careful that you do not drop the bolt inside the timing belt covers as you will have to remove the covers to search for the bolt. Porsche sells the entire shaft and roter already assembled P/N: 94460290100. The mechanic at the Porsche dealer (Downtown Fine Cars, Toronto) where I bought my roter said that this is the recommended way to replace the roter although the other way works as well.

yup....do what brit says..... had to do the same thing 2 months ago when I did my headgasket.............

wait!
take a small easyout, (the left hand thread ones), and if its too big get a smaller one and if its to small, CAREFULLY grind the end off till it just barely starts in the hole and carefully, (AGAIN), turn it out. this has worked for me before a few times.
that screw isnt that tight, you goofed up the socket thats all.
or just go ahead and break everything.

The reason that screw is so tight, it the factory manual reccomends loctite on it.

Before you go grinding anything first try a torx bit socket. Make sure it's in there snug, tap it in with the hammer. Tapping sends vibrations through the bolt to the threads it will help loosen the bolt and then turn with short quick hard turns. If this doesnt work try the dremmel.

I used a Dremel tool and just cut a slot into the end of the screw. Then used a screwdriver and backed it out.
