I don't trust Haynes,goes back a long way i.e. 1975.Had a Triumph Tiger 650 replaced clutch exactly as Mr.Haynes picture showed i.e. with lock nut shown wrong way round!! Me brother warned me it was wrong but he was a mere apprentice mechanic,clutch came loose and tried coming through casing after 10 miles.Norbar good torque wrenches were/are made in Banbury?

I had this with the golf MK2 drive shafts the Haynes manual said 235Nm so they used to pop out when driving lol..
Found out it was more like 435Nm

Hmmm... Often an illustration on the effects of torque helps from a drug crazed mind.....  |

Maybe this is my fault. The 'timing rotor bolt' they refer to is perhaps the one that holds on the actual big rotor on the LHS of the engine. That bolt is a 12 x 40.
I should have seen the signs. As I was tightening the bolt up something did not feel right at all.

You just never know, with out doing an xray stress test before hand lol That's why formula one etc just use them once and replace them.. |

Reference Formula one application,they use bolts made of "exotic" materials and use rolled screw threads that are much stronger which enable a smaller/lighter bolt to be used

Thank you again to those who offered help and advice, particularly the old man, Crouchville and DFS. As soon as the bolt snapped I was thinking 'this bike is now scrap' due to me thinking that the whole crank would have to come out. I came in and started looking at complete cranks on eBay but the size of the job would of meant it would probably not have been worth it. Another forum result as great minds came together - hopefully all the suggestions made will help me as well as others who ever find themselves in a similar situation in the future. Rock on.  |

Hi Mate I think you were lucky to get out of that one so easily . Like someone else said always use new bolts especially when it comes to engine and running gear. Using old fixings is only done on Wheeler Dealers Ed chucks them in the Gunk spays them with WD 40 and they are as new. Dad |
