The Zenoah K550021141 crankcase gasket is intended as an RC replacement for the G230RC, G240RC, G260RC and G270RC engines. It is supplied without packing and serves to restore the sealing face between crankcase halves during rebuild or maintenance operations.
Prior to fitting the gasket, clean mating surfaces thoroughly, remove residual gasket material and oil, and confirm dowel and bearing alignment before final assembly. The part is meant for maintenance and repair tasks rather than for modifying engine performance.
