Description
Overview:
The Big End Shells (Pair) Undersize 030 are genuine Villiers bearing shells for restoring the connecting rod big-end on Villiers small petrol engines, including MK12 and C12. Supplied as a matched pair of half-shells, they seat in the con-rod and cap to support the crankpin. Each shell uses a rigid steel back with an anti-friction bearing layer to maintain the correct oil film and resist wear. The 0.030 in (0.76 mm) undersize suits crankshafts that have been reground by this amount, bringing oil clearances back within specification. Using these OEM-grade bearings helps reduce knock, stabilise oil pressure, and extend engine life on compact industrial and garden machinery powered by Villiers single-cylinder engines. Genuine Villiers part for assured fit and performance.
