stripped belt tensioner allen bolt

[lee polowczuk]

I had to replace the alternator on my m104 engine.

The belt tensioner hex bolt is stripped.... but I was able to get the alternator off by undoing those bolts and sliding the alternator out.

Welll, that doesn't work on the install. belt is too tight

Bottom line--- what is the best way to loosen and remove the stripped belt tension allen bolt? the stripped head is 10mm.

this looks like it's going to be a toughie.

i figured it out...i took two pulleys off to get better access... just the front part of the allen head was stripped... i was able to lightly tap in the allen.. and break the bolt...

i am very fortunate there..

Whenever I get a stripped Allen, I usually hammer in the equivalent Torx bit. It has worked every time.

Good advise! I have a stripped allen head on one of my rotor buttons on my W140... I may give it a try! It is in a tight spot however.

I use the Torx bits that attach to my 3/8ths drive ratchet. As long as you can get a good swing, it will mold itself into the stripped Allen head.
