Description
Overview:
The Crankcase for Stihl MS150T Chainsaw (MPN 1146 020 2902) is the main engine housing that supports and aligns the internal components of your saw. It is a genuine Stihl OEM part designed for compact professional and domestic arborist saws such as the MS 150 T and MS 150 C. Built from a robust die-cast metal alloy with precision-machined interfaces, it provides structural rigidity, protects the crankshaft and bearings, and keeps sealing surfaces true for reliable compression. Correct crankcase geometry is vital for smooth running, power delivery, and long service life. This replacement unit restores the core strength of the powerhead when the original casing is cracked, worn, or damaged, ensuring a proper fit with factory tolerances.
