Stripped Wheel Bolt Thread...options?

[JamesE 5]

When my replacement hub was fitted earlier on in the year one of the wheel bolt threads stripped in the hub.

When I've tried to use a new wheel bolt obviously it won't screw in. I'm presuming the bolt threads are sat in the hub threads. What's the easiest way to get them out?

 

Do I need to get a 'chase'? If so does anyone have a link?

 

Thanks

Tap?

 

A three piece set, taper, intermediate, plug type, although prob be sorted with the first one.

Ok so does tapping mean to recut the thread? If so won't it be a different size?

Try tapping it out. Put a new wheel bolt in and torque to 100Nm. If it won't tighten it will need helicoiling.

85nM is the book torque iirc

Strip off enough stuff to get a tap in from the back, there`s enough room.

 

I`ve found that enough undamaged thread remains at the bottom of the hole, to start it and guide it easily, use some lube too.
