## Long description

Replacement oil pump GEKO G81139 is designed for mid-sized petrol chainsaws with 43cc–58cc engines. The component features a metal housing and a standard mounting interface that fits many common chainsaw frames. It supplies a controlled flow of lubricating oil to the guide bar and chain during operation, helping to reduce friction and wear for more consistent cutting performance and extended bar life.
Advantages
The metal housing delivers improved durability compared with plastic assemblies and resists deformation under heat and vibration. The pump provides steady oil delivery aligned with engine speed to maintain proper chain lubrication. Its standard mounting and inlet/outlet positioning simplify replacement tasks and reduce installation time for mechanics and DIY users. The construction is compatible with common oil lines and fittings used on mid-size chainsaws.
Suitable for
Maintenance and repair of petrol chainsaws with 43cc–58cc two-stroke engines
Replacing worn or leaking oil pumps to restore bar and chain lubrication
Workshop servicing where a durable, metal-bodied pump is preferred
Key specifications
Compatible engine displacement range: 43 cc to 58 cc
Housing material: metal
Mounting style: standard chainsaw pump mounting for mid-sized models
Function: supplies lubrication to guide bar and chain
Flow control: proportional to engine speed (mechanical drive)
How to use
Before installation, ensure the chainsaw is switched off, cooled and the spark plug is disconnected. Drain or contain any residual oil in the system, then remove the guide bar, chain and clutch cover to access the existing oil pump. Unbolt the old pump, noting the routing of oil lines and the orientation of the drive connection. Install the GEKO metal oil pump in the same position, reconnect oil lines and secure fasteners to the manufacturer's torque recommendations. Refit the bar and chain, verify oil feed by running the engine at idle and observing oil flow onto the bar tip, and check for leaks around fittings before normal operation.
Usage recommendations
Use compatible chain oil of the correct viscosity for your operating temperature and follow the chainsaw manufacturer’s guidelines for oiling rates. Inspect hoses and fittings during installation and replace any brittle or damaged lines to prevent leaks. Periodically check oil delivery and clean or replace the pump if flow decreases to maintain safe and efficient cutting performance.
