Zenoah Two-Stroke Crankcase Gasket Replacement

This crankcase gasket provides the seal between the halves of small Zenoah two-stroke RC engine crankcases. It is sold as a hobby spare and not for use in full-size engines.

Compatibility is restricted to the models shown in the product title: G260PU, G231-260PUH, and G231-290PUM. Always check the engine code on your unit to confirm a match.

Fitting advice: clean mating surfaces thoroughly and remove all old gasket material, then lay the new gasket flat without stretching. Use the least amount of approved sealant where required, and tighten bolts evenly in stages to avoid distorting the crankcase. After assembly, test for air and fuel leaks at low throttle settings.

Impact on tuning: a proper crankcase seal helps stabilise crankcase pressure, which supports smooth idle and predictable throttle response. Replace any gasket that looks hardened, torn, or unevenly compressed.
