Hello
The rivets on the clutch plate on my chummy are loose. I have purchased some new ones and was wondering the best way to replace them. Should they be done hot? Do I need a press or just a big hammer? What about using Loctite between the two faces.
Your input would be much appreciated.

Adrian,

I have had a lot of success tightening the existing rivets but did replace the rivets once, it was done cold.

Thanks Ruairidh.
I have tried setting them this morning and they seem softer than I'd imagined.

I used aluminium pop rivets with countersunk heads. Seems OK so far. I punched the "nail heads" out of the rivets before assembling the clutch (just in case)

I didn't read this properly did I? I was thinking of the lining rivets. Steve Hainsworth very patiently pointed out the error of my ways! For the centre rivets I made new ones from suitable bolts. Used the biggest hammer I could find, hit them as hard as I could.

I hope you did not crack the flange on the splined centre by hitting it too hard. I am speaking of experience!

I'm pretty good with a hammer as when I was about 3 yrs old my father gave me a hammer, a block of wood and a tin of nails, to keep me out of mischief. Soon I couldn't see the wood for the nails.
Anyway, the Bantam has a plain disc exactly like early A7, but the splined centre is thick, strong, tough and female. (I'd better say no more in case the digital nanny notices)

A complication is that the holes are often very oval, which means even home turned rivets do not suit. I have not tried on these parts but have been told by one long experienced Seven authority that a carbide drill can be used to reform the holes. Of course all a waste of time if the splines worn.

Worn rivets or splines lead to a clacking noise esp at low speed in top as the drive alternates.
