Description
Overview:
The Piston Ring for Makita brushcutters is a genuine OEM component made for reliable sealing and long service life. Manufactured to Makita specifications in a durable steel alloy, it restores and maintains cylinder compression in two-stroke engines, helping to minimise blow-by, stabilise power output, and support cleaner combustion. This ring is designed specifically for Makita machines such as the ER2550LH and RBC2510, ensuring the correct fit and clearance without modification. Supplied under Manufacturer Part Number 257979-8, it is suitable for routine maintenance or an engine refresh when performance has dropped, starting has become harder, or fuel efficiency has declined. A sound piston ring helps protect the cylinder and piston from accelerated wear and keeps your brushcutter running smoothly under regular use.
Key Features:
- Genuine Makita OEM part (MPN 257979-8) for assured compatibility and build quality
- Precision-machined to maintain correct compression and reduce loss of power
- Durable steel alloy resists wear and heat in demanding two-stroke applications
- Direct replacement for worn or damaged rings; no machining required when used with serviceable components
- Helps improve starting, throttle response, and fuel efficiency
- Supports smoother idling and consistent cutting performance under load
- Made to the correct profile and tension for Makita cylinders to limit blow-by
- Suitable for preventative maintenance during seasonal overhauls
- Easy to fit with standard hand tools when following engine service procedures
- Genuine part status helps ensure long-term reliability and parts support
Typical Applications:
Used during brushcutter engine servicing to restore compression and power, especially after high hours, loss of performance, or visible ring wear. Ideal for routine refurbishment, top-end rebuilds, or after a scored ring has been identified. Maintains dependable operation for landscaping, garden maintenance, groundskeeping, and light commercial site work where consistent cutting and reliable starting are important.
Also known as:
Compression ring, cylinder ring, engine ring, piston sealing ring, top ring. These terms commonly refer to the same functional component that seals the combustion chamber in small two-stroke engines used in handheld outdoor power equipment.
