Stihl OEM Oil Pump Assembly for MS 231, 251 Chainsaws 1143 640 3201

OEM oil pump assemblies are a high quality replacement option for your Stihl 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 loose down time when it eventually goes out.
