The Screamin’ Eagle Hydraulic Cam Chain Tensioner and High-Flow Oil Pump Upgrade kit updates the cam chain tensioner of the Twin Cam 88 to the hydraulic design used on the TC96 and TC103.
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% and scavenging by 50% when compared to the 1999-2005 Original Equipment oil pump, and reduces operating temperature of bearings to improve bearing life.
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.
