WANTED top engine mounting bolt for Honda C90z2 (wider diameter bolt)

[Tom1989]

Thanks for the suggestion Nabs and loadedtoad, I've enquired to see If I can get that bolt customised or one made up

[Tom1989]

Got a reply, they said they probably can help but there's a lead time of 6 weeks or more and they charge £55 hourly rate

[nabs]

isn't it worth trying the triumph version? You might get away with chopping an inch of the end and cutting a new thread and , if it doesn't work , you will only be out of pocket £8

[Tom1989]

Thats true I've never had to make a new thread for something of that size, what would be the best way to go about that?

[nabs]

best would be to find a local engineer's shop near you as they would do it properly.

Otherwise I have a set of imperial dies I inherited somewhere and don't mind ordering one of the studs and having a go on your behalf. I don't know if it will work, but I have got an original part to compare to and, if it does work, you can stick a tenner in a charity box and have the knocked-up version, and if it doesn't work we can both chalk it up to experience!

[Tom1989]

Thanks so much for the offer! I think I might have a tap and die set somewhere I'll just need to check if I have the correct size, if I don't then I would be very grateful if you could do that' I don't mind paying you to do it. Just a question what would happen if I used the later engine mounting bolt with smaller diameter? Would it cause the engine to shake or vibrate too much?

[loadedtoad]

If your not bothered about it being concours buy a piece of 10mm by 1.0mm threaded bar and two half nuts and two full nuts and just make your own.
Ideally it should be a shanked bolt but it will work OK.

[Tom1989]

Do you happen to know the length of the engine mount bolt for the C90z2?

[Tom1989]

I've ordered one of the Triumph cylinder studs, I'll give it a go as I have a tap and die set. Found one on ebay for £7 free delivery so I may as well give it a go! Thanks for that suggestion, if that doesn't work then I'll try buying a threaded rod and cut it down

[loadedtoad]

I'm working away till Thursday i can measure it then unless someone else replies in the meantime.
