W123 rear wheel bearing removal help needed

Dear All,

I thought I'd call this thread "How rough should I get" but I've already started one by that name for my propshaft removal... I'm kind of in a similar position though with the rear wheel bearings.

I'm following the instructions on the Peach Parts wiki :-

http://www.peachparts.com/Wikka/W123RearWheelBearings

I'm stuck at the beginning. I've de-staked the locking on the slot nut and I've bought (at great expense from the dealer) the MB special tool (115 589 02 07 00).

The special tool fits like a dream - so no problems there. Only I don't know how much torque it is designed to take.

Does anyone know this?

I reckon (based on my weight and the length of my 3/4" bar) that I'm applying about 400Nm / 295 lbs ft but the slot nut is just stuck fast. In fact it is laughing at me...

So what should I do:-

1) Buy a longer 3/4" bar and try again?
2) Think of another solution like drilling the bloody thing out?

I've now killed 4 bolts on the wheel side of the hub trying to stop the hub from rotating. I don't want to kill my special tool - I still need it to fit the new bits!

Any advice will be greatly appreciated.
