What is the correct torque for the primary crankshaft sprocket nut. this is for a 2000 S3. I hear the srevice manual torque of 190 ft lbs is wrong. Thanks Brian |

IIRC, it's 190-200 ft-lbs. Torque for XB was revised up to ~250 ft-lbs, but AFAIK value was never changed for tubers. If your torque wrench won't go that high you can usually find a "loaner" tool at your local auto parts store that will. Just be sure and clean crankshaft and nut threads thoroughly with brake cleaner or similar, apply ample quantity of red Locktite, and bring up to torque quickly, before the Locktite starts to set. It helps to have a second person to keep the bike on the stand(s). |

190-210 with red thread lock. Red. Very important. My torque wrench doesn't go that high. I put some tape at the two foot mark on the handle, and had my 100 lb daughter stand on the tape mark = 200 lb/ft. You could also stand on the 1 foot mark if you weigh 200 lbs. If no one of suitable weight is available, do some math for your body weight and figure out where you have to stand. Low tech, but physics is physics. |

Thanks everyone I know this torque is important. Have threads cleaned and red loctite ready. Will borrow a torq wrench that goes above 200. |

I'm not overweight, I'm high torque!

My torque wrench does not go to 200, so I just tighten it to 100 twice.

Love that. Oddly enough the torque value given for a DeHavilland Beaver prop nut is "a 140 lb man on the end of a 4 foot bar". Its actually in the maintenance manual (my numbers might be off, its been a while) practical and easy, except for finding a 140lb man. |
