You just need to grind in a couple of slots for the jaws of the puller to grip to. On opposite sides.
Thank you, I'm just confused on where to drill slots on the flange, as it's mounted flush inside the flywheel groove. I'm trying a new idea, I'll report back..! (I think there may be another flywheel/flange design, I've seen pictures of a different setup!)
I did mine a couple of months ago. I watched a video on YouTube You are correct in thinking you have to tap the old one round a bit then put the bolts in threaded holes and tighten them. It jacks it out as you tighten each bolt
I figured it out! Much easier than rotating the flange slightly (which I could never achieve!): Simply screw in 2 M6-1.00 screws into the flange, opposite sides. Flip it over on the bench, sit the flywheel on a center spacer to allow the flange to be pushed out. (I used a large frame slider!) Hold flywheel on one side by hand, insert a medium Phillips screwdriver into the flywheel side, corresponding hole opposite the flange screw(s), and TAP hard with a hammer. The flange will slowly work itself out of the flywheel. Keep switching sides to ensure even ejection. Job done!
I just supported the outer edges of the flywheel on some wood blocks, then tapped the two screws shown evenly and the inner hub popped out.
Nice, mine wouldnt move or budge a mm. It joined that clutch spacer from my old 916 by being thrown as far as possible into the woods in front of my house. Blasted thing.
