RE: New rear tire time......a tale of woe - 2

Front fork pinch bolts are another favorite target for tire shop philistines. The alloy of the lower fork legs is easily and permanently distorted by over-tightening.

My 2 cents…for what it’s worth,

1. If you must use an impact wrench on the rear (presuming using a lubricant and a breaker bar isn’t enough) block the wheel up with wood pieces so it can’t rotate. That may take the stress off the rear drive.

2. Save receipts. A BMW shop has no excuse for tightening things beyond torque value. If damage to the rear drive happens in trying to get the bolts out, I’d take the shop to court.

I would be very concerned with regards to the mounting plate holding the wheel on to the bevel drive splines. BMW had a recall against my old R1200ST for this very same reason!
Over torque of wheel bolts could crack this mounting plate.
At the time, after 10years of ownership it seemed rather cautious by bmw when the error could be by third parties but good customer support.
Maybe this does require some main dealer or BMW contact in view of customer confidence in their service department and your safety?

I use an electric impact also. Rear brake is applied during the process.

On cars, I use a pneumatic impact wrench to loosen wheel bolts/nuts. For reinstallation, I spin them on with the same one set to low which is reliably 60 ft lbs. I then finish up with the torque wrench.

On the bike, I'd only use a small, electric impact wrench to loosen, never tighten.

The Bolts are far stronger than the plate that they secure the wheel to . So first if they are real tight take the bike of center stand and put it on the side stand . the loosening action is counter clockwise pulling the bike backwards onto the side stand with no chance of a fall . Next one can leave in gear and use a strap to apply rear brake . Often times a bike or cars lugs can be torqued properly but things like sand , chemicals , and other debris can cause a much tougher time removing them. Impacts have their place , and I believe BMW uses a 5 lug star impact drive on assembly that tightens all at the same time .

Kroil a deep penetrating oil works very well .

I have just removed both wheels and brakes for a good clean prior to new tyres in a few weeks, let's me add some wheel bearing grease, rough up the brake pads, clean pads and pins etc.
Because of this thread I decided to test and alter my usual rear wheel removal.
Rather than "in gear (1st ?) and applied rear brake" I left transmssion in neutral and with bike on mainstand had my son assist as usual with just pressure on the rear brake pedal.
This method works both for removal and refit of the five wheel nuts, which did surprise me just how much brake resistance there is.
I was going to test the "on sidestand, in gear method" BUT I suffered the sidestand curse last week!
I "never use the sidestand away from me" - except the channel tunnel and any ferry before a tie down, even at home the bike sits on it's main stand!
I stopped on dartmoor at a reservoir, the only one I know with a free carpark and toilet, bike left on side stand facing uphill, all secure (I thought)
Came back to bike resting on it's right side on the grass and only one van in the carpark, which had not moved.
Camper then advised me, "a gust of wind and the bike fell over"
Some how it was just 'resting on the grass bank' with a broken wing' (right side mirror) but nothing else - good news/bad news.
Not a mark anywhere, tanks, exhaust, screen and rear rack all clear and only some mud/grass on/in the stainless bmw engine protector, annoyed but lucky I think!

That was a lucky escape, I assume you were in neutral? That side stand is really not fit for purpose.
