Here is an example of the clutch hub holding tool. This is from my Husky manual, but it is the same for GasGas. You could buy one, but it would be easy to make one. That's my plan in the future...
Here is what you do:
- Find an old steel clutch plate (NOT the fiber one). The steel plate has the inner teeth to fully engage the hub.
- Weld a piece of flat steel bar stock for a simple handle.
- Bend handle as needed to clear the outer clutch basket.
- Slide the homemade wrench onto the inner hub (see Tool B in picture).
- Hold your homemade wrench and remove the nut with a socket.
- Note: This tool is useful for getting the correct nut torque during reassembly.
An air gun/impact wrench works fine (that is what I used previously), but I plan to make a simple steel plate holding wrench my next time around.
