This Genuine Stihl crankshaft (OEM Part No. 4144 030 0400) is a core engine component for selected Stihl 56‐series two‐stroke machines, including FS56 brushcutters and HT56C pole pruners. Made from high‐quality steel and precision machined, it converts the piston’s linear motion into smooth rotational drive for the clutch and cutting system. Built to factory tolerances, it helps maintain correct engine timing, balance and reliability. Use it as a direct replacement when the original crankshaft is worn, bent, seized or otherwise damaged. A correct, model‐specific crankshaft is essential to restore starting, idle quality and full power, and to prevent further wear to bearings, seals and the cylinder assembly across compatible Stihl trimmers, brushcutters and combi tools.

Key Features:
– Genuine Stihl OEM part for assured fit and compatibility (4144 030 0400)
– Precision‐ground journals and balanced webs for smooth running and reduced vibration
– Durable steel construction designed for the high loads and temperatures of two‐stroke use
– Direct‐fit replacement for the 56‐series crankcase with no modification when installed to spec
– Restores engine performance after crank, big‐end or main bearing wear
– Supports reliable starting, consistent idle and full power under load
– Compatible across multiple Stihl models to simplify spares management
– Manufactured to factory tolerances to help protect bearings, seals and cylinder components

Typical Applications:
Used during engine rebuilds or repairs on Stihl trimmers, brushcutters and pole pruners when symptoms include knocking, excessive play, difficult starting, poor idle, seizure damage or reduced power. Suitable for preventative maintenance where high hours or contaminated lubrication have compromised the original crankshaft. Ideal for restoring dependable operation in domestic, professional landscaping and grounds maintenance tasks.

Also known as:
Crank, crankshaft assembly, engine shaft, rotating shaft, main shaft, crank axle, con‐rod and crank assembly. These terms describe the same component that links the piston and connecting rod to deliver rotational drive to the machine’s transmission and cutting attachment.
