Description
Overview:
This Oil Pump (1.15 mm stroke) is a Genuine Stihl OEM component for professional and heavy-duty chainsaws, including the Stihl MS650 and 066. Built with a durable metal body and precision internal parts, it meters chain oil from the tank to the bar and chain to keep cutting components lubricated under load. The fixed 1.15 mm stroke delivers a consistent oil feed to help reduce friction, minimise bar wear, and support smooth cutting performance. It is designed as a direct-fit replacement, restoring reliable lubrication where the original pump has worn, seized, or become inefficient. Ideal for routine maintenance or overhaul, it helps maintain cutting quality and prolongs the service life of bars, chains, and sprockets on compatible Stihl saws.
Key Features:
- Genuine Stihl OEM part for assured compatibility and quality
- 1.15 mm stroke for reliable, consistent oil delivery to the bar and chain
- Robust metal construction for durability in demanding site and forestry use
- Helps prevent premature bar and chain wear by maintaining proper lubrication
- Stable oil feed supports smooth cutting and reduced friction and heat

- Designed for efficient performance with standard Stihl chain oils
- Straightforward to fit with basic workshop tools, no modifications required
- Suitable for regular maintenance or full saw rebuilds
- Supports longer service intervals by maintaining correct lubrication flow
Typical Applications:
Used to restore or maintain dependable bar and chain lubrication on Stihl professional chainsaws in forestry, arboriculture, firewood processing, construction site work, and milling. Ideal when oiling is weak, intermittent, or has failed, or after major servicing where a new pump ensures consistent lubrication under heavy cutting loads.
