| Post subject: | Play on rearwheel |
I have deteced some "play" (is this good English?) on my rearwheel. When I put the bike on the centerstand I can move (Wiggle) the rearwheel. It is not much but I suspect this indicates that the bearing are worn. Does anyone know howmuch "play" is allowed and should I replace it rightaway? My fear is that the rearwheel could jam while I am having a go! I also noticed that the rear break can move a but forward and backward (in the direction of rotation). Is this normal? Would be great to have some comments! regards, Hans |

Yes, 'play' is the correct word, hvv. The workshop manual doesn't specify any allowable play, but just says the bearings should be replaced if there is 'excessive' play. On my bike I could not detect any play in either the wheel bearings or the brake assembly. I think you should take it all apart and have a closer look. |

hvv, I don't think that you should be able to detect any play at all. If there is play something is wrong. I also think you are right to strip it and have a look. Paul |

Paul and Skins thank you for your reply's. I feel kind of stupid but I found the cause. It was something that should have been checked first: the rear wheelnut was not tightend properly. I fastened it and the play was gone. Hans |

:thumbup: Good stuff, hvv. Do you think your chain tension is OK now? It's very important to get that right. |

| Post subject: | Bearing Dimensions |
Hello, even though you have fixed, please get the Rim out and check the bearings! If you still have the 16" OSCAM Rims like 906Paso, here are the dimensions of the bearing: Outer Diameter: 42mm Inner Diameter: 20mm Width: 16mm The FAG (Bearing Manufacturer) number is: 63004.2RSR Left and right side are equal, costs are (Germany) about 17,- Euro each. There are two more bearings placed in the chainwheel adaptor. Can't tell you more about this ones... 
But check them too! Had the same prob a couple of days ago, broken outer ring... 
Hope it would help you. Greetz, ducster |

:thumbup: of course it does! Tried to get the bearing at the local Ducati dealer... He only had the microfiche from 907ie and would like to sell me a couple of bearings from M900-900ss??? 
Instead he did not recognize that 906 had 16" rims :ugh: Good for me that i've had the rim in car, so i could verify the item
Dealers handling of my request felt for me just like: Get this "terrible horrible old fashioned bike using customer" out of my "new fashioned fully designed ultra-elegant Yamaha-Triumph-Ducati Shop"! :screwy: :thumbdown: btw: a local bearing manufactury, called IBC (very competend and helpful people there! :thumbup: ), could deliver every standard metric sizes only. The bearing of the OSCAM's is a low frequented model and out of normal metric range. Seems that only FAG is producing this ball bearing. Thank god there are some more bearing dealers in my nearest country, so i could get some after, :confused: i think, 3rd request....
btw2: is my "old fashioned" shool-english just understandable? :confused: |

:thumbup: Your English is crystal-clear, Ducster! And welcome! It sounds like you're going to be a good man to have aboard. We've got quite a few now. |

I have a little tip about ball bearings. As you probably know, the bearing number is usually stamped on the seal, shield or sometimes the bearing itself. These numbers are an international standard. Before going to a bearing house, or heaven forbid, the dealer, check with a local electric motor repair shop. If they are anything like me, they will keep a good selection of bearings in stock at about half the price of a bearing house and much less than a dealer. Regards, B |

hvv, If you had continued to ride, (with excessive rear wheel play), you may well have had to, (ultimately), join the 'Paso Oil Leak' group! Glad you found the cause of the problem. The generic bearing numbers are very, very useful - thanks ducster. I will be having a 'away day' from the Paso, tomorrow, as I have to take my son to Heathrow airport in the morning. Safe riding. |
