RE: Boot won’t stay in place. - 2

Well, it’s back together. The manual I have says the pivot bolt is torqued to 100 nm. No way…I suspect that’s what caused the damage. I went to 35 nm and stopped…using thread locker on the bolt.

Attached is a PDF of the repair job.

The r1200GS torque values (which should be the same or similar) are 100NM. This video may assist.

Good video and explanation.
My old R1200st failed in exactly the same place, rollers were rusty and either the roller sleeve fibre washer was missed originally or it fell out somehow.
There was no wear on the sleeve but nothing relating to the fibre washer remaining, just surface rust..
Water got inside the bearing and first indication was a rust stain down the casing.
After my removal the local bmw dealers carried out the fit of a new bearing on the bevel unit for me, which includes the bearing sleeve and fibre washer in the kit.
All other bearings (I also removed the swing arm casting) were perfect, still covered in assembly time grease, so maybe some bikes left germany without this protective washer.
The biggest issue I had was getting that white fibre washer to seat in the bearing sleeve on assembly as any excess grease pushed out on tightening wanted to unseat that washer.
I did tighten to the correct 100nm and also purchased a hollow, cut-out socket for swing arm pivot as you need to fit the brake lever side plate first, 3 bolts, low value torque setting, then the gear lever side.
Again this needed one torque setting for the pressure towards the opposite side, brake side plate, but a much higher setting to lock the in place.
Hollow socket lets you hold the torqued fitting in place before fully tightening the lock nut.
I know the torque settings seem high but they are there for a reason and I would think if this was too high it would have had a bmw service recall/reset by now.
Any under tightening would surely affect the whole rear end, wheel movement under cornering loads?
I say this because when my rear drive was rebuilt after advice it was allowing too much wheel movement on an mot as an advisory only.
After the bevel rebuild it did improve handling at speed on a constant radius turn.
What had been a slight wallow on one local downhill curve completely cleared so for me those bmw spec values is what I would use.
This very minor movement did affect the handling and I wonder if this 35nm rather than 100nm will be the correct option.

Based on the responses from several, I removed the bolt and retorqued it to 100 Nm as specified. I wonder if I accidentally went to 100 ft lbs last time. Maybe the failure had nothing to do with this. I just hope it doesn't come back. I'll update the PDF.
