This helical gear is an OEM part that is sold separately. If you notice your chainsaw is making unusual sounds while in operation, it may be due to a worn helical gear. After years of use they can start to wear and will need to be replaced. The helical gear consists of the gear pressed onto the driving roller spindle.
