MCS Cams Bushings

MCS cam bushings give Harley-Davidson engine builders the precision-tolerance bearing surfaces needed to support the camshafts within the engine crankcase during a cam service or full engine rebuild. The cam bushings control the radial position and running clearance of each camshaft — worn bushings introduce lateral play that affects valve timing consistency, creates noise in the valve train and accelerates wear on the cam lobes and tappets. MCS supply cam bushings machined to the dimensional specifications of Harley-Davidson Big Twin and Sportster cam chest configurations, with interference-fit sizing that ensures correct installation without excessive driving force or under-size bore conditions that leave play in the joint. Correct bushing selection requires knowing whether the engine uses a ball-bearing or bushing cam support plate, as the housing geometry differs between designs. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries MCS cam bushings alongside a full engine rebuilding and valve train components range.
