Replaces centrifugal clutch system and boosts performance
Clutch is asymmetric-type torque converter system with asymmetric
sheave faces, this makes it possible to force the belt to a diameter within
the drive clutch (at high rpm) that exceeds the usual 1:1 drive ratio
TAV2 system can actually attain a .90:1 ratio (10 percent overdrive)
Belt and two variable pitch pulleys work together as a clutch and variable transmission. Weatherproof system is completely mechanical and can be mounted in any position. Unique design allows automatic infinite variation and smooth shifting action between the systems high and low range in response to changing loads and travel conditions. Maximum 8 HP. NOTE: Briggs & Stratton changed the bolt pattern on some 8 HP engines, so you may need to make an adaptor to fit these converters to your application. Bore Diameter (in.): 1, Tooth Design Pitch (in.): 40/41, Application: Torque converter kit
