SCREAMIN’ EAGLEHYDRAULIC CAM CHAIN TENSIONER AND HIGH-FLOW OIL PUMP UPGRADE KIT
Spring-loaded cam chain tensioners on older engines require service, so customers with older Harley-Davidson® motorcycles will appreciate this upgrade. The Screamin’ Eagle® Cam Chain Tensioner and High-Flow Oil Pump Upgrade Kit features a hydraulic tensioner, which is designed for the life of the engine. This upgrade kit will reduce and/or eliminate wear and provide a higher level of confidence to the customer that this wear will not be an issue going forward. This kit upgrades their spring-loaded tensioners with the current, late model hydraulic tensioners and improves the oil flow within their engine.
BASIC DETAILS YOU NEED TO KNOW
The Screamin’ Eagle® Cam Chain Tensioner and High-Flow Oil Pump Upgrade Kit updates the cam chain tensioner of Twin Cam 88 engines to the latest design, as featured on the Twin Cam 96™ engine. The kit includes an improved Screamin’ Eagle® High-Flow Oil Pump that provides increased oil pressure and oil flow. In addition, ’02-’06 models utilize a Twin Cam 96™ single row front roller chain and sprocket (included in kit). ’99-’01 models use Original Equipment front silent chain and sprocket to retain the cam position sensor function. This popular upgrade for older models has been designed and tested to Harley-Davidson factory specifications.
How Does It Work?
The larger pump roters increase the oil supply by 23% and scavenging by 50% when compared to the ‘99-’05 OE oil pump. The increased oil flow reduces operating temperature of bearings to improve bearing life
The cam plate is CNC-machined billet aluminum and is heat-treated to 6061-T6 specifications to enhance its ability to support high valve spring pressures on cam lobes . Installation requires specialized tools; dealer installation is recommended
Fitment: Fits ’99-’05 Dyna® models, ’00-’06 Softail® models and ’99-’06 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.
Opportunity: It is important to realize that the OE tensioners are a wear item for Twin Cams built between ’99-’06. Our Hydraulic Cam Chain Tensioners will significantly outlast the OE spring-loaded tensioners on these older model Big Twins and are an ideal addition to an engine modified for improved performance. Performing this upgrade will reduce or eliminate future service intervals of the cam chain tensioner. This is also a perfect opportunity to install the Screamin’ Eagle® High-Performance Inner Cam Bearing Kit, P/N 24017-10, which provides an increased load capacity and extends the engine life.
