Prompt responce from Sinner, they would send me a replacement axle. One could argue that such a critical component should not fail. Still, it does Sinner credit that they did not make a fuzz out of sending a replacement axle. Free of charge. Keep in mind that this Mango is from 2008; in Europe warranty does not typically last as long. I did not have to wait long for the replacement part to arrive, all in all I'm happy with the service Sinner gave me.
Let's get cracking.
I applied some anti-seize to the axle in case I would have to remove this one someday. I don't know if I did a good thing with the anti-seize, but I figured it could'nt hurt. I hope the future will not prove otherwise.
Sinner adviced me to try to use the new axle to push the old out. Although this helps, I assisted myselve by 'devising' a pulling mechanism using a wrench.
Aligning the axle on the bolted side is a bit tricky, a small mirror helps as one can't look around the corner...
Up till know I've been riding with a 'workaround', yet this did not result in a proper chain alignment. I've been longing to fix this for a while now. The original 26 tooth sprocket had larger holes, I replaced it with a 22T one, in order to ease the climbing of some slopes.
