Description
Overview:
The Big End Shells (Standard) are genuine Villiers bearing shells for the connecting rod big-end on Villiers MK12 and C12 petrol engines. They support the crankpin and maintain the correct oil film, helping the crankshaft rotate smoothly under load. Manufactured from durable, precision-engineered bearing materials for long service life, these standard-size shells restore correct clearance when replacing worn bearings and help prevent knock, heat build-up, and premature wear. Marked with OEM No. EM913 STD, they are intended as a direct-fit service replacement for engines used in a wide range of light industrial, agricultural, and garden machinery. As unused old stock, surfaces may show minor tarnish from storage, which does not affect performance once installed and lubricated.
Key Features:
- Genuine Villiers part for assured compatibility and fit (OEM EM913 STD)
- Standard size shells for straightforward replacement without machining the rod
- Precision bearing surfaces support stable oil film and smooth crank rotation
- Helps restore correct running clearance and reduce vibration and noise
- Durable construction suitable for continuous small-engine duty cycles
- Suitable for routine overhauls or targeted big-end bearing renewals
- Consistent sizing for reliable assembly and correct torque-down of the cap
- Compatible with Villiers MK12 and C12 engines used across many machines
- Unused vintage stock; cosmetic tarnish from storage may be present
Typical Applications:
Used during engine rebuilds or repairs on machinery powered by Villiers MK12 or C12 engines, such as lawn and garden equipment, small construction tools, generators, pumps, rotavators, and mixers. Ideal when addressing big-end knock, low oil pressure linked to bearing wear, or after crankshaft reconditioning (standard journal).
