Description
Overview:
This cam shaft is a precision engine timing component for the Robin/Subaru EH25 petrol engine. Built from robust steel, it synchronises the opening and closing of the intake and exhaust valves with the crankshaft to keep combustion smooth and efficient. A worn or damaged cam shaft can cause hard starting, loss of power, and poor fuel efficiency, so timely replacement helps restore reliable running. Designed as a direct replacement for OEM No. 254-31701-41, it suits EH25-powered construction and garden machinery such as compactors, pumps, generators and small plant. Its accurate lobe profiles and solid journal surfaces support stable valve operation across the engine's working range, helping prolong the life of associated parts like lifters, rockers and timing gear.
Key Features:
- Direct replacement for OEM No. 254-31701-41 for straightforward identification and fitment
- Steel construction for strength and wear resistance under continuous service
- Precision-ground lobes to support consistent valve timing and smooth running
- Helps restore starting, power delivery and fuel efficiency on EH25 engines
- Suitable for routine maintenance or overhaul to reduce unplanned downtime
- Compatible with typical EH25 timing gear and standard installation practices
- Designed for reliable operation in demanding site and garden environments
- Supports correct valve lift and duration to protect related valvetrain components
Typical Applications:
Used on equipment powered by Robin/Subaru EH25 engines, including plate compactors, generators, water pumps, pressure washers, chippers and tillers. Ideal when refurbishing engines that show timing wear, poor idle or misfires. Suitable for scheduled rebuilds to keep hire fleets, site equipment and domestic machines dependable and within expected performance.
