Custard TLC

[TLPower]

Aside from forthcoming vendetta's involving offspring, have you tried ptfe tape on the threads? It works.

[Fat Rat]

I think the one in question has had a Helicoil before, remnants of it were attached to the bolt when it came out.

[tallpaul]

Are you confident of the thread being m7? If it is tapped for a helicoil then it will be oversized. Or did you measure the screw?

B*gger. Remnants.

OE Screws M7. When I put the new Helicoil in it will still be M7  

[Jacko]

Tap it out to an M8?

[tallpaul]

Only asked as m7 is a curious size!

The bike's looking very nice! I'm enjoying this thread.

[Fat Rat]

M7 is weird but actually the bolts appear on many of Suzuki's bikes (GS500 DRZ400 GSXR750 GSF1200).

I'll Helicoil it Jacko as I want to use the OE bolts and even though they are well hidden an odd one would drive my OCD nuts

....m7 is a curious size...I'm enjoying this thread.

I see what you did there, very good!    

[Mr B]

Don't helicoil if you can avoid it - use a "timesert" much better as it's a solid.

[Fat Rat]

I have used both and have always had excellent (permanent) results with each.

[Jacko]

The lip to stop the insert screwing into the hole on the timesert would concern me, what if you needed a flush mating between components?

[Shebee]

Not guilty on the previous helicoil!  May have been the main dealer the previous owner used that we were discussing when you were here... But Custard is coming up lovely... Maybe time to rename her creme anglais as being a lot posher than custard?

[tallpaul]

Timeserts have spotfacing cutter in the kit for making a recess for the lip to sit in. At least the kits I've seen have one in.

[Jacko]

That would be a great solution.

[Fat Rat]

The tasks I have left to get this bike back on the road are small but I am really struggling for time  

Anyway, today;

Helicoil kit eventually arrived    so I set about repairing the M7 thread for the Rocker Cover.



In the kit you get a Drill Bit, a Tap and the tools to insert the coil and to break off the tang (the small lug used to locate in the tool to wind the coil into the new thread.



I read somewhere that it's bad to fill your engine with bits of swarf so I took the part off that needed attention.



Drill out the damaged thread and tap a new one using the Tap provided



Load the coil onto the tool



Wind in the coil



A nice new M7 thread

[Jacko]

Slick.

I've never done that before, so now I'll view you as an expert should the time come.

[Fat Rat]

I'm not an expert at anything. Unless I'm selling my services to a paying employer, then I invented the solution  

[MartinW]

... I read somewhere that it's bad to fill your engine with bits of swarf ...

That's just an "Old Wives Tale", it will be alright
