Description
Overview:
The Crank Shaft Cp - Robin Part - RB274 20101 51 is a replacement crankshaft for small petrol engines, designed to restore smooth and reliable running. Built from high-strength steel with precision-ground bearing surfaces, it converts the piston's linear motion into rotational drive for the flywheel and output shaft. Manufactured to match original dimensions and tolerances for the Robin Subaru EH09 engine, it supports correct oil film formation and maintains engine balance under load. This part suits compact construction and garden machinery where consistent torque and durability are essential, such as plate compactors, generators, water pumps, and lawn equipment. Fitting a quality crankshaft helps reduce vibration, prevent premature bearing wear, and keep your engine delivering stable performance over long service intervals.
Key Features:
- Precision-engineered journals and crankpin for reliable oil film and reduced wear
- High-strength steel construction for long service life under heavy use
- Balanced to minimise vibration and protect surrounding components
- Direct fit for EH09, matching original geometry and clearances
- Heat-treated surfaces to resist scuffing and fatigue
- Corrosion-resistant finish to protect during storage and operation
- Compatible with standard OE bearings, seals, and connecting rod
- Supports smooth idle and consistent power across the rev range
- Manufactured to meet or exceed OE specifications for fit and function
- Straightforward installation with standard workshop tools, minimising downtime
Typical Applications:
Commonly used in small engine-driven equipment such as plate compactors, trench rammers, generators, pressure washers, water pumps, tillers, and mowers. Ideal for restoring performance in hire fleet machines and privately owned tools where the original crankshaft has suffered scoring, out-of-round wear, or impact damage.
