If the clutch is coming apart do you nedd instruction how to replace the clutch?
Customer: replied 7 years ago.
I don't know, is the clutch coming apart or is there a loose bolt(s) that can simply be tightened? Too little space for me to tell.
Expert:  EMRSR replied 7 years ago.

There is only 1 bolt on the clutch, it is highly unlikely it has loosen up.

On your sent image, the clutch disc and hub (#2) feels loose. The three bolts that form a triangle on that disc feel loose. Are they bolts or other? Why would they feel loose?
Expert:  EMRSR replied 7 years ago.

The 3 that form the triangle are not serviceable bolts. #2 is drawn to #5 by #6. You need a clutch. I have attached the instructions, it is really a relatively simple but time consuming task. You can rent/borrow the tools from most parts stores like an Auto Zone. Print this on first viewing in case it times out. You will need help on the evac and recharge.
