Description
Overview:
This connecting rod is a direct replacement part for Robin/Subaru EH12 petrol engines. It links the piston to the crankshaft, converting the piston's up‐and‐down movement into the rotary motion that drives your machine. Built to original equipment dimensions under OEM reference 252-22501-20, it supports smooth, efficient running when fitted during an engine rebuild or repair. The rod features a high‐strength aluminium alloy body with a precision‐machined big end and small end to suit the EH12 layout, helping to maintain correct clearances and oil film. Suitable for a wide range of compact construction and garden machinery powered by the EH12, such as plate compactors, generators, water pumps, and small mixers, it is a practical choice for tradespeople, DIY users, and maintenance teams.
Key Features:
- OEM reference 252-22501-20 for precise EH12 compatibility
- High-strength aluminium alloy body for dependable service life
- Precision machining at both ends to help maintain correct journal clearances
- Robust cap-bolt design for secure clamping on the crankshaft journal
- Matches original length and journal sizes to preserve engine timing geometry and balance
- Helps reduce vibration and wear by keeping piston motion accurately controlled
- Suitable for workshop or on-site engine rebuilds with standard tools
- Compatible with typical lubricants used in small air‐cooled four‐stroke engines
- Designed for reliable performance in continuous-use applications common on site equipment
- Supports smooth starting and consistent running when used with sound crank and piston components
Typical Applications:
Used in Robin/Subaru EH12 engines found on compactors, small generators, water pumps, cement mixers, chippers, and turf care equipment. Ideal for scheduled overhauls, replacing a scored or ovalised rod after lubrication issues, or restoring an engine suffering from noise or loss of efficiency due to big-end wear. Suitable for workshop rebuilds and field repairs across plant hire, landscaping, and facilities maintenance.
