While replacing my sprag spring I've gone to lock my crank sand the locking bolt is just turning in the casing , it doesn't lock the crank properly as I can wiggle the bolt and hit comes out. Any ideas would be appreciated. Helicoil ? re-tap . I'm not sure what size helicoil, tap , drill sizes etc . I would have to order taps ,helicoil etc as I don't have them at hand. The locking bolt was from sportax not a homemade job. Thanks |

helicoil, std 8mm bolt. Done a few in my time, dont need to be that tight to hold the crank as long as you have a point on the end of the bolt |

Thanks Monty, ordered a helicoil kit off the bay earlier , I think I should drop the sump to retrieve the piece that gets snapped off the insert & the drill swarf. I'm changing the oil as half of it is on the feckin drive anyway.. feck . Its been one of those days where everything I touch goes tits up.

Nice thing is, just drop the plate under the engine and at same time clean the sump filter, only 6 x 6mm cap heads |

Yes , ordered a sump seal kit from sportax , I put new mesh in last year so it should be straight forward . Thanks again Monty. |

Be careful with the helicoil.. especially when putting the blanking bolt back in.. I've seen them where the helicoil then screws into the engine which is not good. I use time sert which have a flange so can't screw into the engine. It is possible to fit on 600's with the crank out of view and sump removed to collect the swarf... |

Thanks for the tip, would I be able to put a small amount of threadlock on the helicoil when inserting to stop this happening.? Thanks |

Worth a try I guess.. fit the sump after you've fitted the blanking bolt... that way you check all is well.. |
