Swingarm adjustment?
O.K.boyz chime in anytime you want...
Perusing the BMW shop manual I came across Swingarm adjustment, stating torque specs but not "how to"... Anyone done this yet? After my Pivot bearing lesson, I'd like to know more about the swingarm procedure. Airheads are known for this maintenance adjustment, along with steering head bearings, etc..., I'm thinking these new boxers are same same...it's just a Beemer thang...

I'm going to check mine sometime this week, and if I need to do anything, I'll take (focused, hopefully, rapid) pix and do a writeup. I've wondered about this for some time now, after the incident of needing to replace paralever pivot bearings at 15K...

Pivot bearings are clearly the weak point. I don't remember anyone having trouble with the swingarm bearings.
Pull the wheel and the shock (hope you don't have an aftermarket exhaust...) and move the swingarm/rear gear up and down with your hands. You should be able to quickly figure out if there is any play anywhere. best, Dave |

Rapid, the swinarm bearings are set the same setup as the pivot bearings. I think they are a slightly larger size, but they are adjusted the same way as the pivot bearings. There is one fixed pin on the right side and an adustable one on the left. It is adjusted the same way as the pivot, by cleaning all the locite off the threads and setting the prescribed torque with new loctite. Then tighten the locking nut while holding the adjustable pin in place.
Like David said though, you should not need any adjustment unless you can feel some bearing play. These bearings probably stay in better shape for much longer than the pivot bearings because they have a longer range of motion that keeps the grease spread evenly. Also, they don't have the high offset loading that the pivots do.

now we're getting somewhere...
Concerning other play in the driveline, I also read that the differential ring bearing can be shimmed if there is play. Anybody have first -and experience with this?

Roger has mentioned working on pinion bearings and shims before. Looks much more complicated and may require special tools. Geez Rapid, you're just looking for trouble aren't you?

Yeah, doing the differential is like doing a car differential....crush washers, measuring bearing depth, adjusting the pinion in or out with dykum and shims and preload torque...it can be done, but experience and practice count here prob'ly more than anything else. If I knew a competent wrence that's good on a BMW M/C diffy, I just might ber inclined to pay for the fix, and I ALWAYS do my own work. I did a few car diffs in my time, and screwed up one or two also....it's not as easy as it sounds.....

No, I'm just trying to pin down the driveline maintenance and how to.
Since this is after all a BMW and the do have drivelines, which means they have maintenance schedules, weather we or our certified dealer mechanics no it or not. I should have known better than to buy this new bike and figure I could get a way with just changing fluids and setting valves...case in point, the pivot bearings I just replaced. So, why not research what else might be required in the driveline department? If you ask most of the service mangers out there, and I suspect the mechanics, they won't know, or don't care. I had one shop tell me that the pivot bearings weren't something that they did, that "no one knows how to set rear-ends up anymore", and that BMW recommends a complete differential swap...$825 retail for us post-warranty guys... Give me a frikkin' break.  These drivelines require maintenance, even if the particulars are'nt mentioned in the service manual. Just like the old bikes... Lookin' for trouble? You bet.

Rapid;
exactly my point that I try to make about these oilhead twins; I (in my blissful ignorance) thought BMW motorcycles needed minimal maintenance.....not so, grasshopper; they need maintenance DIFFERENT from a japsikkle, but it seems, not LESS of it. Just a mechanical device, but the bluster and luster of the aura of 'BMW reliability' is more horseapples than substance, if ya ask me, as my perennial question of 'how is a paralever shaft drive that needs bearings every 25K better than a chain and sprockets?' has never even been addressed by every official-bmw type I've cornered; they usually mumble something about 'BMW's are different', then bail out as soon as possible. I love my S, but I'm not blind to it's considerable faults.

Hogwash
...and to ad a point of reference...
I called the only shop left in the state of Califas that I know and completely trust and they in turn said of the first shop's comment, "Hogwash! Complete and utter Bunk..."

Unfortunately, that's largely true. Many shops don't have staff around who are good at that. The advice on the swingarm bearings being just like the pivot bearings is good. Just keep things torqued and greased. It's not rocket science, as long as you stay out of the rear drive proper.
