Step 1: Get the carter off
Step 2: Make sure you have a piston stop or vario block have. If you use a piston stop, turn it where the spark plug is normally. If you use a vario -block key, then block the vario and loosen the nut for the half -poulie.
Step 3: Now slide the rings and inserts off the axle, also slide the half -poulie off the axle.
Step 4: Now you can take the V-belt off the Vario side for a while, and then you see a ring sitting against the plane of the VARIO who touches the V-belt.
Step 5: Remove the variation, it is a similar ring like in the photo. 1 or more rings can be mounted, you can get both off.
Step 6: Move the V-belt again and also slide the parts removed at step 3 in the same order on the axle.
Step 7: Block your Vario again and tighten the nut at the Vario again.
Step 8: Install the carter hood again.
