Oil Pump Governor Rotor

The governor rotor with centrifugal valve is driven by the scavanger pump idle gear. At low and intermediate speeds, this valve diverts the oil into the timing case and thus limits the oil supply to the engine. At high speeds, the centrifugal valve closes and the entire oil feed goesto the crankshaft until the bypass-valve opens and limits oil pressure to about 30 lbs.

Hydraulic Cam Chain Tensioner Plate Upgrade Kit

This kit updates the cam chain tensioner of your early-model Twin Cam 88 engine to the latest design, as featured on the Twin Cam 96 engine. The billet cam support plate has been designed to allow the installation of the late-model hydraulic cam chain tensionser to early Twin Cam-equipped models. These hydraulic cam chain tensioners will significantly outlast the spring loaded tensioners, and are an ideal addition to an engine modified for improved performance. In addition, '02-'06 models use the included late-model single row front cam chain and sprockets ('99 - '01 models use the existing front silent chain). The kit includes the improved late-model oil pump that increases flow by 8% and scavenging by 22% to enhance other performance upgrades.
Installation requires the separate purchase of a spacer kit.
