Screamin' Eagle Cam Chain Tensioner and oil pump upgrade
Harley-Davidson Press Release - Oct 5, 2011

The new Screamin' Eagle^® Hydraulic Cam Chain Tensioner and High-Flow Oil Pump Upgrade Kit (P/N 25284-11, $499.95) from Harley-Davidson^® Genuine Motor Accessories updates the cam chain tensioner of a Twin Cam 88^® engine to the latest hydraulic design features on Twin Cam 96 and 103 engines.

The hydraulic cam chain tensioner is significantly more durable than the original spring-loaded tensioner, and is an ideal addition to an engine modified for improved performance. 2002-2006 models utilize a Twin Cam 96 single-row front roller chain and sprocket. 1999-2001 models use the Original Equipment front silent chain and sprocket to retain the cam position sensor function.

Each kit includes an improved Screamin' Eagle High-Flow Oil Pump that provides increased oil pressure at high-operating temperatures. This kit increases the oil supply by 23 percent and scavenging by 50 percent when compared to the 1999-2005 Original Equipment oil pump, and reduces operating temperature of bearings to improve bearing life.

The Screamin’ Eagle Cam Chain Tensioner fits 1999-2005 Dyna^® models, 2000-2006 Softail^® models, and 1999-2006 Touring models. Installation requires separate purchase of Spacer Kit P/N 25285-08, Cam Service Kit P/N 17045-99D and Drive Gear Retention Kit P/N 25533-99A.
