Hi Pandu;

I know this problem and i have done many replacements of this friction materials without dismantling the complete unit.

The replacement friction material i buy in a local handy shop, they sell round felt pads wich have a sticker ( with a paper protector on it ) on one side, these pads are sold to stick on furniture and small objects ore other items so that they don't scratch the furniture etc. They sell these with different thickness and sizes.
I use one with about the same size like the original. ( Mostly they are sold in a plastic bag with several on 1 page )

Then i punch a hole in the center of this round felt pad ( about 6 a 7 mmm ..this is for the center axis )

Then with a cissor i cut from the side to the hole ...so only a cut to the center..not completly in half.

Then i loosen the screws of the flywheel and the clutches to make some space to work.

Then with a screwdriver and a small knife i remove all of the old frictionmaterial and clean it with a alcohol ( ipa ) as clean as possible.

Finaly with a pointy-nose pliers or using tweezers i can place the new pad in place ( first remove the paper protector from the sticky site )

Finaly, reajust the spacing....Job done !

Succes.... Greetings Dirk
