Zenoah K207521140 Engine Crankcase Gasket - Fits G260PU / G231-260PUH / G231-290PUM  [K207521140]

Gasket Replacement for Zenoah RC Two-Strokes

This gasket replaces the sealing element between the two crankcase halves on Zenoah small-scale two-stroke RC engines. It is intended for hobby use only and not for full-size machinery.

The listed compatibility is exact: G260PU, G231-260PUH, and G231-290PUM. Verify your engine code before buying to confirm compatibility.

Fitting tips: inspect mating surfaces for damage and remove any old gasket residue, clean both faces, then position the gasket flat without stretching. Only use a minimal amount of a manufacturer-approved sealant if absolutely necessary, and tighten bolts evenly to prevent crankcase distortion. Perform a leak check after assembly at low throttle.

Why it matters: maintaining a proper crankcase seal helps sustain compression and steady crankcase pressure, which in turn supports consistent throttle control and idle stability on two-stroke RC engines. Replace any gasket that shows wear or deformation.
