Description
Overview:
This Crank Shaft Oil Seal is a genuine Villiers replacement for MK20 and MK25 engines (OEM E9720). It is a metal-cased, rubber lip seal that sits in the crankcase housing and seals around the crankshaft to prevent engine oil escaping while helping to keep dirt and moisture out. Made from durable, oil-resistant rubber with a rigid steel outer shell, it is well suited to vintage stationary engines used in garden and light construction machinery. Ideal for servicing and full rebuilds, it restores correct sealing and helps maintain reliable lubrication. As unused vintage stock, the part may show light tarnishing or storage marks, but this does not affect function. Designed specifically for Villiers MK20 and MK25, it provides the correct fit and sealing profile.
Key Features:
- Genuine Villiers part for assured compatibility with MK20 and MK25 engines
- OEM reference E9720 for quick identification and ordering accuracy
- Rubber lip with steel outer case for secure fit and long service life
- Helps stop oil leaks at the crankshaft to reduce mess and oil loss
- Supports smooth running by keeping oil in and contaminants out
- Straightforward press-in installation with appropriate tools
- Suitable for restoring vintage engines; unused stock may show cosmetic ageing only
- Replaces worn, hardened, or leaking seals during routine service or rebuilds
Typical Applications:
Used during maintenance or restoration of Villiers-powered machinery such as vintage lawn mowers, rotavators, small generators, pumps, and light construction equipment. Ideal when addressing oil leaks, after crankshaft work, or whenever the engine is apart for inspection. Helps extend engine life and reliability in regular use or show-condition restorations.
Also known as:
Crankshaft seal, radial oil seal, main crank seal, crank end seal, engine oil seal, shaft oil seal. These terms describe the same function: sealing the crankshaft where it passes through the crankcase to retain oil and exclude contaminants.
