Sprocket removal for chainsaws OLEO MAC (year 1988)?
The teeth of the sprocket are worn out and I have to change it. But I have a hard time removing this sprocket : The 10 mm head nut is hard to unscrew, and I worry to break the shaft.
Do I have to force or is there any tip to solve my problem?
Thanks a lot for your help
