Gates Accessory Drive Belt P/N:7730
Gates 9640HD belt drive components for the 1974 Jeep Cherokee 5.9L / 6.6L and other vehicles and equipment carry power on heavy-duty drives as a single notched V-belt.
A worn belt can show cracks, fraying or a squeal under load. With the engine off and cool, look over the notches and the overcord first. Pulley alignment or belt tension can cause similar noises, so find the cause before you swap the belt.
It also fits the 2007-2012 Caterpillar D6T and the 2009-2012 Caterpillar D7E. If your machine is not named here, look it up in the "Vehicles it fits" section.
