Titan 424-285 AX-27 Grip Notch Belt
OEM Titan Drive Belt
Titan 424-285 AX-27 Grip Notch Belt is an OEM high-performance V-belt that transfers engine power to the pump or drive train on compatible PowrTwin and PowrLiner line stripers, ensuring consistent power transmission and reliable operation.
Compatibility Overview
Grip notch design features transverse grooves that increase flexibility, reduce heat buildup, and provide superior grip on small-diameter pulleys compared to standard wrapped belts. A worn, cracked, glazed, or stretched belt causes slippage, reduced pump output, squealing, and erratic machine operation. OEM replacement restores original drive efficiency and prevents downtime.

Titan 424-285 AX-27 Grip Notch Belt for PowrTwin & PowrLiner Stripers
Titan 424-285 is an OEM AX-27 Grip Notch Belt designed for the drive system on compatible Titan PowrTwin and PowrLiner line stripers. This high-performance V-belt transfers engine power to the hydraulic pump, gearbox, or main drive train, enabling the pump to pressurize and deliver coating material for professional pavement marking applications. The grip notch profile features transverse grooves that increase belt flexibility, reduce heat buildup, and provide superior grip on small-diameter pulleys compared to standard wrapped belts. This design results in reduced vibration, smoother operation, and longer service life. The belt corresponds to the industry-standard AX-27 profile, with an approximate outside length of 29.2 inches and a 1/2-inch top width. Over time, belts can become cracked, glazed, stretched, or oil-soaked, leading to slippage, reduced pump output, or complete failure. A worn belt may also cause squealing, vibration, or erratic machine operation. Replacing with genuine Titan part 424-285 restores original drive efficiency, eliminates slippage, and prevents costly downtime. Always verify compatibility against your specific sprayer's parts diagram, as drive configurations vary across models and production revisions.
