The oil pump drive transmits rotation to the oil pump of the Good Luck chainsaw and ensures lubricant is delivered to the chain. Country of origin: China.
Replace it if the gear or worm teeth are worn down, or the housing is cracked. Sign of wear: the saw does not deliver oil even though the tank is full and the channel is clear.
When replacing, clean the seat of dirt, oil and sawdust and inspect the neighboring parts: a worn unit often drags the others with it.
