N.O.S. Alpha Bearings Norton Model 40 350cc International Big End Bearing Assembly Ref: N51S for 1932-1952 engines.

Standard pin diameter.

Alpha Bearings inspected the pin and it is to drawing. This is one of their original older style pins, N51S assemblies and in mint condition.

Unfortunately my flywheels had wear to the journals so I had to have a new pin made up, making this surplus to requirements. I had Alpha make and supply a new big end liner for the assembly as the original had already been fitted to the conrod.

Ideal if you have unworn flywheel journals or having new standard flywheels machined.

Condition is New. Dispatched with Royal Mail Special delivery.
