STIHL 3-Piece Oil Pump Repair Kit — Diaphragm, 2 Sealing Gaskets & Oil Strainer for Models 009/010/011/012

Complete 3-piece repair set: 1 oil pump diaphragm, 2 sealing gaskets and 1 oil strainer supplied for a single maintenance job. The new diaphragm and strainer restore consistent automatic oiler operation, ensuring dependable bar and chain lubrication for smoother cuts and extended equipment life. The pair of sealing gaskets forms a tight seal between the oil pump and crankcase to stop oil leaks and preserve proper system pressure. Built as a direct OEM replacement to the original specifications, this kit installs easily on STIHL 009, 010, 011 and 012 chainsaw models. Replacing these wear-prone parts on schedule helps maintain cutting performance and prevents damage caused by insufficient lubrication.
