Supermiata Damper thread diameter/pitch
 
So, I acquired a Supermiata damper for my shitbox.

I plan or grabbing a 36-2 trigger wheel

Does anybody know the size of the fasteners required?

Emilio posted for torks in another thread

No spec. Just snug. I'd do 50-80 in/lbs. Loctite 243 (blue)
I spent time googling but no luck

But I will obviously need to chase down fasteners

thanks!

Wrong bolts. The SPM damper is interference fit onto the crank shaft using the crank bolt. I believe he's looking for the small SHCS's that secure the trigger wheel to the back of the pulley.

Middtenn is on teh money - this sucker is held in by friction and the crank bolt. I need the hardware to attach the trigger wheel. The little guys pictured above. I saw in another post EO2K found he needed a 7/64 bit to drive the screws so also a notmetric size to make things more fun.

I kind of expected that I would need to contact supermiata for this info (I need to order the trigger wheel anyways) but if i can get it in a public thread for future reference, that is a good repository for that info; for the community.

Or just get out the tap set. :rofl:

I will drill and retap some time in September when they arrive.

Let me try to check the size of those bolts. I would be surprised if SPM does not sell them. I can say they are 7/64 standard Allen key.

Thanks to everyone who has contacted me with helpful info

I emailed supermiata
