Crankcase Gasket for G260PU and G231 Series - Zenoah K207521140  [K207521140]

Crankcase Gasket Specification for Zenoah Engines

This gasket seals the joined halves of small Zenoah two-stroke RC engine crankcases. It is a hobby replacement component and should not be used in full-size engines.

Confirmed compatible models are those listed in the product name: G260PU, G231-260PUH, and G231-290PUM. Verify the code on your engine casing prior to purchase to ensure correct selection.

Installation recommendations: clear away any remaining gasket material, inspect mating faces for damage, clean thoroughly, and position the gasket flat without stretching. Only employ a minimal amount of manufacturer-approved sealant when necessary, and tighten fasteners evenly to prevent crankcase warping. After reassembly, run the engine gently to check for leaks before normal use.

Effect on engine behaviour: a sound crankcase seal maintains consistent crankcase pressure and compression, which supports steadier throttle response and idle. Replace compromised gaskets to retain reliable engine performance.
