Husqvarna 505 19 99-04 OEM Oil Pump Assembly for 545, 550 XP Chainsaws 505199904

OEM oil pump assemblies are a high quality replacement option for your Husqvarna chainsaws. Oil pumps are one of those wear items that get little attention until they quit working. Like all moving parts, they will eventually give out with prolonged use and need to be replaced, especially when running low quality bar oil or used motor oil. We recommend on having a back up oil pump in your shop, so you don't lose down time when it eventually goes out.
