518570 Camshaft bushing, outer. std. 36-69 OHV

When you are rebuilding the cam chest on an early Big Twin, the tolerances on your bushings can make or break the build. This MCS outer camshaft bushing is a standard-sized replacement designed for the cam cover. It fits 1936 through 1969 FL models, covering everything from the Knucklehead through the Panhead and into the early Shovelhead years. This precision-machined bushing ensures your camshaft rotates smoothly and stays properly aligned within the cover. It is a direct replacement for OEM number 25581-36. In the shop, we always check these for wear during any cam swap, as a fresh bushing is the best insurance against premature gear wear and mechanical noise in your vintage drivetrain.
