Description
Overview:
Big End Shells -030 Undersized (Pair) for Villiers engines are precision bearing inserts for the connecting rod big-end journal. This genuine Villiers set is made from durable, bearing-grade metal on a rigid steel backing to provide a stable running surface for the crankpin. The -030 specification suits crankshafts that have been reground by 0.030 in (approx. 0.76 mm), restoring correct oil clearance and smooth operation. Supplied as a matched pair for one con-rod, they are a direct replacement for Villiers MK12 and C12 engines. Marked to OEM reference EM913/030, they fit correctly without modification. As unused old stock for vintage engines, light tarnish may be present but does not affect performance. Ideal for rebuilds where reliability and long service life are required.
