12K service
 
While performing my 12K service and checking the torque on the fasteners my concern is the lower shock bolt.The lower shock bolt torque of 100nm seems high to me, the access to the bolt is also quite problematic. Is there a special tool or trick one of you has discovered for accomplishing this and is the torque in the Haynes manual off for this bolt? Gary

The torque is correct and it a pain. I used a craftsman male socket, an extension and some cussing.

That bolt has factory-applied dry locktite right?

Stupid question time: If you check torque on such a bolt and it turns ... have you ruined the "locktite" :huh

I don't think it will turn checking the torque. I would estimate it takes about 500 NM of persuasion to break it loose. I had to use a 1/2" breaker bar and just about had to stand on it to break it loose.

Lemme see here...
 
From memory, so beware: The BMW manual tells you to remove or loosen the chain guard so you can get to the little screws on the rubber swingarm protector. You remove those screws, which go through some little dished washer dealies, then you can slide your 6 (or was it 12?) inch extension tipped with a T50 Torx head under the rubber. Might want to first clean out any grunge that's collected in the bolt head. Seems I had to the countershaft sprocket cover as well. It's not rocket science, just more work that you think it should be. Makes the beer taste better when you're done! :1drink

Shock lower bolt
 
Thanks for the comments. The chain guide has a hole in it to pass the tool through. What I bought is a torx T55 tool from a MAC dealer. I'm in the process of modifing it. It costs 24 dollars and some change and when modified it will do the task easily. When removing the fastener it is a good idea to heat the lug on the swingarm to soften the locktite. Also like you said clean the head of the bolt. I would like to add that adding a little valve grinding compound to the tip of the tool will make it grip the fastener alot better. I tried to add alink to MAC tools website but they don't have a picture posted with it.

My bad, it IS a T55. I bought a 55 and a 60 because I couldn't be sure which would fit and couldn't find an answer in the normally encyclopedic annals of AdvRider. Was obvious that the 60 was enormous when I got them home. My T55 bit was only $6, works like a champ on an extension. I lifted the chain guide anyway...it was pissing me off :splat

A "bit" off topic (and didn't want to start another thread for this, but wanted to put it out:), just came back from my 6k service (+ the 2 year one) and I had to pay 108! This is the cheapest service I've ever payed (except the very first (600miles) one on my old single). Even the 6k service on my 650GS single (+ the 1 year one) was like 160. This was unexpected! I'm really really happy with that Twin :clap
