Description
Overview:
The Big End Shells U/S 020 for the BSA 320CC Industrial Engine are precision bearing inserts that support the crankshaft journal at the connecting rod. They are Genuine Villiers parts (OEM No. 86 1374) made for dependable service in stationary and industrial engines. The U/S 020 size denotes a 0.020 inch (0.51 mm) undersize, intended for use with a reground crankpin to restore correct oil clearance. Built with a robust metal-backed construction and a precision bearing surface, these shells help reduce friction and wear, stabilise oil film, and protect the crankshaft during heavy use. Supplied as unused old stock, they may show cosmetic tarnishing from long-term storage, but remain suitable for service once inspected and correctly installed on the BSA 320CC Industrial Engine.
