Description
Overview:
The Piston Ring Set 0.25 - Robin Part RB227 23512 07 is a replacement ring kit for small petrol engines, sized for the first oversize (0.25 mm) rebore. Built from wear‐resistant metal alloys, the rings provide a precise seal between piston and cylinder to restore compression and control oil. This helps engines start reliably, run smoothly and maintain power under load. Designed for Robin engines such as the EY20, the set is suitable for many compact construction and garden machines that use this engine platform. Supplied as a complete set for one piston, it is intended for routine overhaul or to resolve symptoms like low compression, hard starting, blow‐by, or excessive oil consumption.
Key Features:
- 0.25 mm oversize to suit first‐oversize bores and standard rebuild practices
- Helps restore cylinder sealing, improving compression and power
- Reduces oil consumption and exhaust smoke by improving oil control
- Precision‐matched ring profiles for consistent bedding‐in and long service life
- Durable, heat‐resistant materials for reliable operation in 4‐stroke petrol engines
- Smooth installation with standard tools; no special modifications typically required
- Supplied as a complete set for one piston, suitable for maintenance or rebuilds
- Compatible with Robin EY20 engine architecture and tolerances
- Supports stable idle, easier starting and better fuel efficiency after overhaul
- Suitable for equipment used in dusty, high‐load job sites
Typical Applications:
Used during engine overhauls or repairs on equipment powered by Robin EY20 engines, including compactors, generators, water pumps, cement mixers, small welders and turf care machinery. Ideal when reboring to first oversize, or when addressing low compression, blow‐by, oil burning or loss of performance.
