Mack

A second V-Belt variant designed for high-demand drive systems on Mack trucks, this belt emphasizes durability and consistent performance in extreme operating conditions. It delivers efficient power transmission to essential accessories while resisting heat buildup, oil exposure, and flexing stresses from engine movement. The belt’s compound and cord construction are tuned for long life under repetitive starts, stops, and highway speeds, helping to maintain stable charging, steering assist, and climate control functions. Proper tensioning and alignment with pulleys are critical to prevent premature wear. Regular inspection should identify cracking, glazing, or frayed fibers that signal replacement.
