Hey guys, long time no post. BLUF after a Hiatus from Motorcycling I am back with an 1150 rt-p.

Problem. I am trying to remove the crash bar support system on this girl and it looks a lot like this.... https://www.ebay.com/itm/BMW-R-1150-RT-R22-Bj-2003-Grundtrager-Sturzbugel-unten-oben-Support-System/132548949231?hash=item1edc8874ef:g:V0UAAOSw~CRTqZjD&vxp=mtr

EXCEPT.... the lower mounts go directly into the crank case. I was loosening the bolt and got a hand full of engine oil..... AND some how it is tied into the kick stand that is obviously cop issued.

The problem lies in finding a shorter bolt to fit into that lower left hole. I pulled the bolt and tried to replace it but the bolt is longer and will not hold the oil if I replace said bolt. I want to say it is 12 or 14 mm I have done several google searches and cannot find a fiche or even a decent parts manual that would show me a part number to order from BMW. ( As is they would have one in stock)
I have seen several "online" fiches and none of them show this bolt that supports the crash guard system yet holds the oil in!

Does anyone have a recent Fiche or parts blow up I can review? Any suggestions?

I have always loved the 1150rts.

Here's a link to the parts breakdown for the R1150RT-P bar system with hardware.
Look lower left and scroll down for otter illustrations such as the bars (chrome) and bracket of his isn't what you need.
It's a little unclear why you struck oil, but I'm sure someone more experienced can help.

Oh my!

I use the Max BMW fiche for my parts reference; their fiche is easier to work with than A & S's. I suggest you check there so we are on the same page.

https://shop.maxbmw.com/fiche/DiagramsMain.aspx?vid=51765&rnd=07242017

The lower end of that mount that you have linked to, called the 'Base Support System, Lower', attaches to a bracket that is shown on illustration 46_0376, item 5. Item 5 is bolted to the bottom of the crank case with an M10 x 90mm fillister head screw (washers, nut, etc.) that is shown on illustration 46_0377 as item 15. I don't remove that screw to remove the 'Base Support System, Lower' which is 46_0376 item 4, BTW, although I did replace that bracket (item 5) previously without any leaking oil. I remove the two small bolts shown as item 8 on 46_0377.

Now... if you are referring to the chrome 'Rod Left', 46_0376 item 1, then you will see that it is bolted to (I believe) the center stand bracket (un-numbered on illustration 46-0377) which has a captive cage nut on it. Again, no oil, but the other end of it isn't attached to the 'Base Support System, Lower'; it attaches to the chrome crash bar.

None of the bolts retaining the 'Base Support System, Lower' go into anywhere there is oil, so I am at a loss as to the problem here. Mine is a 2004 and I presently have all that stuff off the bike to do an alternator improvement and clutch replacement.

What's different about yours??

Does this help at all?

Coupla CB750s, a CB900C and an '04 R1150RTP Yammy is gone.

Morning dughawk

It sounds like you are working with a non OEM attachment bolt. The 1150 RT-P bars do not usually attach with bolts that go all the way through the engine block & into the crankcase oil. (the holes for the bars are blind)

Your bike sounds like either someone installed a bolt that was too long then hit it with an impact wrench & forced it to blow out the inside alloy then into the crankcase. OR, someone stripped that bolt so then drilled all the way through into the crankcase then threaded the hole deeper to take a longer bolt.

Without seeing exactly what you are working with it is very difficult to advise but you are probably going to have to measure the bolt in question, then determine what you need to use as far as length & thread pitch, then buy that from a fastener supplier.

Or possibly make a bolt into a stud then clean the stud & crankcase hole, then install the stud with a permeant Loctite. Then use that stud with a nut on it for future bar removal.

You probably have some viable options but we will need very clear close up pictures of the bolt & engine area to help you, and/or you will need to be creative in finding a workable option.

Thank you all for your replies.

Since I do not have the tools, parts and such to make an effective repair, I am going to take this to a dealer and have the BMW mechanic tell me what he thinks as well. The more I played with it, the more I believe it was a non OEM FUBAR, I will post again in May as to the Progress of this project since I am currently busy in RL As always, thank you all for your suggestions and I will keep you appraised to the restoration. Cheers to the best Forums on the Interwebs!
