#1 Clutch flywheel dowels

Post by Gfhug » Wed Jun 03, 2026 11:48 am

The flywheel and clutch have two or three dowels depending on size of clutch. Are these dowels a tight fit so that they shouldn’t come loose or is some form of thread lock used to hold them tight in the flywheel? Searched the forum didn’t couldn’t find an answer.

Thanks for any help, Geoff

Hello Geoff,
They should be, and generally are, a tight fit, requiring a dowel puller for removal when the face of the flywheel is being remachined.

Regards,

Bill

They’re probably hardened as well.

So if you find you have to make new ones because the holes are worn I’d use something like 4140 which you can easily harden as necessary.

Andrew, thank you. SNGB sell them for not too outrageous a price so I’ll buy from them. But it’s good to know the alternate.
