Description
Overview:
The Big End Bearing R2 (34.40 mm) Undersized is a Genuine M.A.G part for the Mag 2055 SRL engine. It sits at the crankpin end of the connecting rod, maintaining a precise oil film between rod and crankshaft for smooth, efficient running. Built from bearing-grade metal with a precision-machined surface, it is designed to handle sustained load and rotation at engine operating temperatures. The 34.40 mm undersize suits crankshafts that have been ground to an undersize specification, helping restore correct oil clearance. Supplied as unused old stock, it is well suited to maintaining or restoring vintage M.A.G engines such as the 2055 SRL. OEM reference 0529 048 supports easy identification for service and replacement on compatible engines.
