Shift knob nut size
 

Does anyone know what the size of the bolt is for the gear shift knob on a w124 is?

I was trying to fit my new adaptor shaft onto it and I could not get the darn bolt off! (Probally because I had the wrong wrenches. :( )

Could I get the wrench at home depot?
I money wrench will not fit in the small space!

I almost got too impatient and started to strip the nut! Goo thing I stopped before it was too late!

Thanks!

It's 15mm. I bought a combo spanner and heated the open ended end 90° as close to the jaws as possible, this did the trick. You might also like to try a 3/8 drive crows foot spanner. It's tight though !

Thanks, I plan to buy a 15mm from autozone... I tried the mercedes tool kit first, but I only found an 8mm, 9mm and a 13mm, 17mm.... sooo close... darn!

Wow 15mm?!! :eek:

I swapped my OEM shifter for a wood-grained one last year, and I don't recall using a wrench THAT big!
hmmmm.... :confused:

15 mm is correct.
