Husqvarna 503 80 83-03 OEM Oil Pump Piston for 334T, 335, 336, 338 XPT, 339 Chainsaws 503808303

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 donAt loose down time when it eventually goes out.
