I think theres space enough on this flywheel for an M6 bolt....... just like ChrisW has...

Geo its my spare heavy flywheel the flywheel in my car is a 'standard' flywheel

thought so already.... (just a try)

Ill use m3 or maybe m4 m3 seems a bit small to me

This morning my boss was put so i looked at flywheel to mount pickup.
M4 is too big for the flywheel and m3 is ok. But only one m3 to hold the pickup on?
Doesnt seem like alot. Im going o use 2 bolts as i dont want my pickup coming off destroying everything in its path!!

There not the longest of bolts either but geuss that isnt too much of an issue

Just curious but is there another way at all to get a sense from egine rather than flywheel?

Nervouse about the pickup to be honest but will try anyway

I think 1 bolt is ok if you secure it with locktite. The Pickup is only 3 gram.
If you make a tide fit it is not possible the sensor rotate.

But 2 bolts that is even beter. Make the pickup like Geo draw in L shape.
If i do it again i will use 2 bolts and an L shape pickup. Just for extra safe.

Drilling and tap threath is easy. I drill 2,5 and tap M3.

When you fit the pickup first rotate the engine bij hand and look if it can rotate free.

Ok will do that
Thanks for the help

Why is the L better just curious

L because you can put 2 bolts in but is as light as possible....

Ok. Will make it L shape. Cheers.

Once fitted ill read this whole thread as many things im curious about

And 1,5mm thick I made the fist 1mm but not strong it wil bend to easy.
