Description
Overview:
This crankshaft is a replacement internal engine component for Stihl lightweight petrol chainsaws. Built from forged, heat-treated steel and precision machined, it converts piston movement into rotational drive and keeps the engine running smoothly under load. It is suitable for compact pruning and maintenance saws such as the Stihl MS150 and MS150C, where low vibration and reliable power delivery are important. The assembly includes the crank webs, crankpin, and connecting rod, with accurately ground bearing journals ready to accept the correct bearings and seals. Identified as part number 1146 030 0400, it helps restore performance in engines suffering from wear, scoring, play, or vibration caused by a damaged or out-of-true crankshaft.
Key Features:
- Forged steel construction for strength and long service life
- Precision-ground journals to support smooth running with the correct bearings and seals
- Balanced counterweights to reduce vibration and improve cutting control
- Accurate fit for compact Stihl chassis to maintain clearances and timing
- Corrosion-resistant finish on machined surfaces for storage and fitting
- Restores compression sealing and power delivery when replacing a worn crankshaft
- Compatible with original engine components, flywheel, and clutch interfaces
- Supports reliable idling and throttle response in frequent start-stop use
- Designed for straightforward installation during a standard engine rebuild (crankcase split required)
Typical Applications:
Used during engine rebuilds or repairs when the original crankshaft is bent, worn, seized, or pitted. Common in arborist, landscaping, and grounds maintenance work where lightweight chainsaws are used for pruning, crown lifting, and property maintenance. Suitable for routine overhauls to restore smooth running and reduce vibration.
