Clutch stuck to shaft
Hello everyone,
On my wr 450 f the clutch was stuck to the shaft as the title suggested. The clutch suddenly engaged after a drive in high temp, and didnt let go since then. i found the problem, but also not really.
I have openend up my bike and after removing the crank case and the insides of the clutch i could lift the clutch itself off. It was somehow tightenend to the shaft, but i dont know why. Because after i removed the clutch, and put it back, everything seems to be working again. the shaft moves freely without noise or resistance without clinging on to the clutch.
my issue is that i dont know why it became stuck in the first place, and im afraid it will happen again. its a road bike, this is very dangerous. If you have any idea why this happened pls let me know as i have no idea and the manual doesnt help me anymore either. my first question would be whether the copper colored plates (pic 2)on the insides are fitted with bearings? but i have no clue what else the problem could be. any comment or help is appreciated!
thanks in advance
