Need spec on a Torx screw

akak1997 · 10-13-2009, 02:56 AM

To install the DSSR for UUC SSK, I'm trying to remove the exhaust tunnel heat shield, and the torx screw (18 in the diagram) that attach the "Tension strut"(17 in the diagram). Do any one know what the size of that torx? I don't have a torx bit (I only have some torx sockets). And those torx bits are stupid expensive!!

Also, I think the torque spec on that one is 21nm, but I still haven't got a CLUE how to read that TIS CD, I can't really find anything...
Are there any other tools I've to use to remove the heat shield?

Thanks In Advance

Best advice is buy a set..I did it. If you plan to do any work on your car you will need them.

Also not sure why you are taking the exhaust out? I didn't when I installed my kit.

The heat shield is in the way, I cannot get my hands on the selector rod at all. Besides, my new exhaust should be here this friday

Also, what is a good set of Torx bit to get? I mean what the common size range BMW uses? Thanks

T-10 to T-50 will work fine, dont over tighten the torx bolts or you'll never get them back out. i just snug them down, 21 nm should be fine

EngPhys09 · 10-13-2009, 03:40 PM

I generally buy the best tools I can with a lifetime warranty so if they break they are covered.
As ghikser said T-10 to T-50 is likely fine.
Don't worry about over tightening...hopefully you are using a Torque wrench.

If you are putting new a exhaust in then I guess it makes sense to remove the old one to ease putting a shifter in :P

I bought a set of tips from Harbor Freight which included Torx but also a lot of other tips. Has multiples of most sizes. The Torx fit several screws on my bimmer fine. I wouldn't consider much of anything Harbor Freight sells the best you can get but it if often good enough. I think I paid about $10.

+1
Or if not this car, then another car of yours, or a friend's car. I bought a set, and have used it enough times to have made it worth it.

Cool, Thanks guys, I'm gonna pick up a set from Sears this week!

Mega Man · 10-14-2009, 11:25 AM

Good man. I got a set from Autozone for under $20. I wanna say $13, but honestly, I don't remember. I know it was for sure under $20 though. They were standard Torx.

They also have the Torx with the nipple in the middle. I think those were a little more. I haven't seen them needed on this car, but I wish I had the set with the nipple a few years back. Honda uses it on certain things they don't want easily opened. Their HID ballasts all have them.

JimD · 10-15-2009, 06:32 PM

Sears is OK for hand tools but not nearly what they used to be. Their current tools seem like the same made in China stuff other people sell for less than Sears. At least that is my take on it. That is why I just buy on price, Harbor Freight is usually the cheapest. But not everybody has a Harbor Freight close by. And mail order from them takes forever. Northern Hydraulic tools seem OK to me too (I'm not saying they're great, just about the came as current Craftsman). Lowes and Home Depot sell about the same kind of tools although my son has better luck with Home Depot hand tools.

For things like screwdriver tips, I get more than one if it is a size I really need. I either break them or loose them.

Hey, sorry to go a bit OT here, but is that largest x-shaped structure in the OP's exploded diagram the rear subframe and 2 & 3 the crappy bushings that MUST be replaced?

Where are you guys getting these exploded diagrams?

Thanks for any info,

ianc

The parts diagrams are from RealOEM.com click on the ENTER tab in the middle of the page.

Torx bit tools - you should get some from T10 to T55. Also a T27 will come in handy for the airbag stuff.

Also... our cars have a lot of torx bolts - they are kind of a reverse Torx head instead of the six side hex bolt head we are use to seing. They are called "E" sockets. Get a 1/2 inch drive set from E10 to E18.

Good Luck
David

I've got a set of these (as well as standard drivers) and they've saved me a lot of time over the years on stuf that's too tight for a regular screwdiver.

Most of the auto parts stores have them and they're less than $30 IIRC:
