MCS Cams Thrustwashers

MCS cam thrustwashers give Harley-Davidson engine builders the precision-dimensioned washers needed to control axial float on the camshaft during assembly and rebuild of the Big Twin cam chest. Camshaft end-float is a dimension that is often overlooked during engine rebuilds, but excessive play in the axial direction allows the cam to drift back and forth within its housing, affecting valve timing, generating noise and wearing the thrust faces of both the cam and the crankcase. MCS produce cam thrustwashers to the dimensional tolerances specified for Harley-Davidson Big Twin camshaft applications, with thickness consistency ensuring that the correct end-float can be set by selecting the appropriate washer from the available range. These are small components that cost little but are critical to correct engine assembly — a missing or incorrect thrustwasher can cause progressive internal wear that is expensive to diagnose and repair. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries MCS cam thrustwashers alongside a full engine rebuild and valve train components range.
