Description
Overview:
This Cylinder Lead Gasket is a genuine Villiers part for 50cc Villiers Light Weight engines used on Atco mowers. The sealing ring measures 43 mm in diameter (1.69 inches) and sits between the cylinder barrel and cylinder head to create a gas-tight joint. Made from soft lead, it compresses evenly under torque to compensate for minor surface imperfections and maintain stable compression. The gasket helps prevent combustion, oil, and gas leaks, supporting reliable starting, smooth running, and long service life. Identified by OEM No. R540, it is produced to the correct profile for a precise fit on the intended engine family, making it a straightforward replacement during routine servicing or a top-end rebuild on applicable Atco mower models.
