Thread repair

Recommended Posts

I've got 3 bolts in tappitt covers on my RM that the threads are stripping out. As these bolts are being taken out each time I do valve clearances I'm thinking a Time-sert thread repair is the way to go rather than helli coil as they are stronger. What size do I need?

I have a box of helicoils to do the job if you are stuck. Not as good as Timesert, but still work ok. And you can have them NOW if that is important.

Hi MartyNZ

I won't have time this weekend so no panic. But many thanks for the offer

Time sert is not cheap. Best price I've got is $220 for kit. That's from Wurth with works discount. Rep trying to get me a better price (Fellow motorcyclist)

Will be worth it if I have to end up  replacing all 16 threads!

I have Time=Sert , Heli-Coil and a kit from Fastenal . For this the heli-Coil would be fine .

Correct assembled Helicoil thread is the simplest and best way. When you insert it deep enough, it will prevent to be unscrewed. The top surface will not be changed.

Thanks guys for the advice. I surpose torque on these bolts wont be that much so helicoil is way to go.

10 Nm total with a little blue loctite is all you need, tighten them in progressive amounts equally in a more or less star pattern across the cover.
