Description
Overview:
This Genuine Stihl crankcase gasket is a precision-cut sealing component for Stihl 046 and MS 460 chainsaws. Made from durable fibre gasket material designed to withstand petrol, oil, heat and vibration, it sits between the crankcase halves to create a reliable seal. A sound crankcase seal is vital on two‐stroke engines to maintain correct pressure and vacuum, helping the engine start well, run smoothly and deliver full power. By preventing air and oil leaks, the gasket helps protect internal components and keeps performance consistent over time. Supplied under Stihl part number 1128 029 0502, it is an OEM fit, removing guesswork during rebuilds or routine maintenance and ensuring the correct alignment of ports and fasteners for clean assembly.
