what's the !~@#$%^&* deal with Mercedes allen bolts!!!????
why o why do they always want to strip when using crapman tools??? especially 5 mm (oil pan) and 8 mm.
I want to replace a flex disc but no matter how careful I work, they WILL strip. so basically you just can't do it. (I have no air) does anyone know of a hex key that is the right size for mb 8mm? don't say use a snap on 8mm because I'm sure there's something wrong with the batch of allen bolts mb used to wrench their cars together. (why use allens anyway)

You must be using he wrong size. I've never had a problem with any of them stripping.

I have had many bolts that were difficult to remove. My guess is the previous mechanic just REALLY tightened everything down, instead of using torque specs. The transmission pan on my SD came off just fine though.
I have heard of folks banging in a torx tool to gain a bite. I've also heard of folks using heat. 8mm is 8mm the world over. The next size up torx is T50, but that's 8.72mm. Before you remove it, make sure you have a new replacement. Good luck.

an 8 mm craftsman WILL strip the mb 8mm allen on the flex disc. I clean out the bolt, make sure it's all the way in, hold the (very thin) 17mm at the back with a snap on wrench, and put force on it. it strips. allen bolts like to strip. it has to be the crapman tool then. I gave up. of course it's the last one that stripped. I'm going to install a manual in my sd next year anyway. at least you don't have to adjust those for days and days before they shift halfway decent.

None of my flex discs had hex heads.

Dont know what your doing wrong but I have removed allot of MB allens and not had a problem and I do use the impact wrench on flex couplings. I did have to use an "easy out" on a motor mount allen that someone had managed to "round out"
Make sure the allen is cleaned out well before inserting the tool.

Usually when they strip its because you didn't get them seated all the way in or you allow the allen to slip from straight in.
If you get a really tough one I keep a hand held impact wrench with allen heads. It is absoulutely essential for the door latch allens. Tom W

I dip the allen socket tip in valve grinding compound to remove stubborn bolts. Craftsman doesn't have real sharp corners on their allen sockets.

you need to buy a good set of allen wrenches, not the sears or harbor freight or home depot ones. go to MSC or grainger and order an industrial set of true "allen" brand wrenches. you will be amazed how nice the allen bolts are when the tool are hardened enough to perform correctly.

yep, if I had air, an impact wrench and a name brand (not crapman) socket it would have been out in 2 seconds...
but I don't. lucky me, the transmission seal doesn't leak and the disc is only just starting to crack a little. good for another 50k I presume. and by then the 280 tranny will go in. plenty of those where this car is going...
