how to open secondary clutch? any special tools needed?

[glowa]

I need to change helix and spring on the secondary, I removed 4 torx nuts in the back but it does not open up. What should I do?

After removing the 4 Torx bolts the helix will come out, turn the clutch over and bang it on the workbench....it should fall out. You will need a spring compressor (or get creative) for the spring change.
