Description
Overview:
The Connecting Rod Bearings Undersize -030 are genuine Villiers big-end bearing shells for the Villiers MK15 series. They restore correct oil clearance at the connecting rod by matching a reground crankshaft journal. Built as metal-backed shells with a precision anti-friction bearing surface, they support smooth, reliable rotation under load and help protect the crank from scoring. Specified as -030 (0.030 in undersize, 0.76 mm), they are intended for engines where the crankpin has been ground to suit. Ideal for maintaining or rebuilding vintage engines, these bearings suit the Villiers MK15 and MK15/2 and are appropriate for workshop or home restoration. Supplied as unused old stock, they may show light tarnish or storage marks that do not affect performance when fitted correctly with clean oilways and correct torque.
