Description
Overview:
This shake-proof washer is a genuine Villiers part designed for the sump stud on classic Villiers small engines, including the MK10 and MK12. Made from durable metal, it provides a secure, vibration-resistant joint between the sump assembly and the stud/nut, helping to stop fasteners backing off during operation. Its design supports reliable clamping in oil-exposed, heat-cycling environments typical of petrol engines used in construction and garden machinery. Ideal for routine servicing or full rebuilds, it restores the correct locking function where wear or ageing has reduced effectiveness. As unused vintage stock, units may show light tarnishing from storage, which does not affect performance. Manufacturer Part Number: E9723. Genuine Villiers quality ensures correct fit and dependable service life.
