Jims Cams Bushings

10 products — part of all Cams Bushings

Jims cam bushings give Harley-Davidson engine builders the precision bearing surfaces needed to support the camshafts within the crankcase during a cam service or engine rebuild, with the manufacturing accuracy and tooling support that Jims is known for in the Harley-Davidson professional workshop community. The cam bushing controls the radial running clearance of the camshaft within its housing — worn bushings introduce lateral play that affects valve timing accuracy, increases valve train noise and accelerates wear on the cam lobes and adjacent components. Jims machine their cam bushings to the exact bore and outside-diameter tolerances required for correct interference fit in Harley-Davidson Big Twin and Sportster cam chest configurations, and supply the associated installation tools needed to press bushings in square without damaging the housing. Jims also supply the reamers needed to finish the bushing bore to the correct camshaft clearance after installation. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries Jims cam bushings alongside a comprehensive engine rebuilding and tooling range.
