clutch slave cyl bolt

Recommended Posts

Vitesse Con 2L. The thread in one of the holes(?) on the bell housing to retain the clutch slave cylinder has been stripped (not quilty)

I have a Clarke RAD-2 right angle attachment and a 210mm long drill bit and, combined, their total length means that I might have to remove the shift mechanism to get the drill in to bore out the hole to fit a helicoil. Which is a bit of a pain.

The drill diameter is 21/64, is it possible to get a shorter drill bit, say half the length. This would allow the combined pieces to fit in the space, between the housing and the shift mechanism, to allow a straight drill into the bell housing hole.

As an extreme measure I could cut a bit of the current drill bit but the owner would not be to chuffed about that.

Any advice would be appreciated.

Like the idea of a self tap bolt BUT I assume the bolt will be steel and then being forced, to a certain extent, into aluminium the two different metals are very likely to weld togther and difficult to remove at a later date?

Taping an 8mm new tthread might be better.

Thanks for the comments, though.

Tap it wider wid a metric 9 MM 1.50r a 10 MM 1.5

or a 3/8th UNC or WHIT

 

thee,s if taper taps,will fit in wid oot needing being drilled

 

goingtoo deep, then the threads can come thru the other end

let water / moisture in, and it seizes,  been there fun it oot

 

And, use a wee bit of thread lok,

then ye no gotta tighten as much, and it wont come loose
