OK to use a TORX 55 socket to remove flywheel ?

[wildcat077]

Hey guys,

I would like to know if it's allright to use a TORX 55 socket to remove the flywheel bolts.The Torx is a six point socket and it seems the bolts are 12 point and require a special socket ...

Cheers !

No!

Use the correct triple square

If you strip it out it is a pain...you can get triple-square bits from sears.ca or Babco.

Thanks guys,
That's what i was thinking,just called my local auto parts supplier to order one ...
Is it OK to use an impact gun to remove the flywheel bolts ? It worked well for the pressure plate fasteners !

Cheers !

sure

Hmm, I've seen the correct tools for sale at several regular old auto parts stores.

Porsche wasn't the only manuf to use them.

Maybe it's different up there, eh?

I've used a Torx to remove and replace my flywheel bolts a couple of times. No problems, just keep square to bolt head and lots of pressure holding it against the bolt.

Steve,

Not to worry,i found a set that i will be picking up after work tomorrow!
Imagine that !

One cannot have too many tools

I'm in the middle of an engine drop due to an exploding clutch and i caught the "while i'm there " syndrome ... lol

Cheers !

You can usually pick up a set of 4 at places like O'Reilly, Autozone, etc...

You could always order them from Pelican Parts for $14.75

I know New Beetles and Passats use them on drive axles. Probably Audi, too.

Heat is your friend when removing these bolts. I use a propane torch to heat up the bolt (it doesn't take much) and they typically come right out. (using a triple square bit). W/O heat they are much harder to remove.

Can anybody confirm if i need an 11mm triple square bit for the flywheel ???
That seems to be the equivalent of a Torx 55 ...

Cheers !

I wouldn't touch these with an impact. Too easy to strip. With the flywheel locked down and a good-sized 1/2" ratchet or breaker, I've never had an issue to remove these. As mentioned, heat may be of assistance on those that need it.

No - See Masraum's link - they do not come in odd # metric sizes. (well, I don't think they do) Probably 12 but I cannot say for sure. I will check the Porsche parts catalog and report back.

Edit - nothing in the parts catalog that defines the bolt socket size with granularity. Also, the parts link provides nothing and the 901/915 clutch replacement provide nothing (tech info center)

http://www.pelicanparts.com/techarticles/911_clutch_replace/911_clutch_replace1.htm (references "special tool") I remember it being 12mm.

take a steel hammer & smack the bolt head flat on - i.e. normal to the axis of the bolt

I had a couple of fwd dodge/plymouth products that were vintage '78-82 that used VW 1.7L motors and transaxles. They used them for the head bolts. I believe I was also told that Ford Pintos used them for something too.

Not the sexy Horizon? Owned one. The intoxicating 1979 edition. What a babe magnet. Sadly, I had no soft Corinthian Leather. In fact, no air conditioning and vinyl seats (in Houston) and the friggin inner fender strut mounting shell rusted at the spot welds and pulled away from the inner fender requiring me to use 30" of all thread to pull the suspension back together and then the front engine mount rusted out and the engine dropped four inches. But I digress.

when you say it like that...it sounds bad.
