Description
Overview:
The Poly‐V Belt 9PJ920 is a genuine Hatz drive belt designed for compact multi‐rib pulley systems on small diesel engines. Made from a heat‐ and oil‐resistant rubber compound with reinforced tensile cords, it provides steady grip and smooth running under continuous use. The "9PJ920" specification denotes a PJ micro‐rib profile with nine ribs and an effective length of approximately 920 mm, suitable for tight installations and small pulley diameters. Used on engines such as the Hatz 2L41C and 2L31C, it drives auxiliaries like cooling and charging systems to keep plant running reliably. Its robust black rubber construction and precise rib geometry support efficient power transmission with reduced slip and wear in demanding site conditions.

- Genuine Hatz part for assured compatibility and quality
- PJ profile, 9‐rib design for high grip and efficient power transfer
- Approx. 920 mm effective length for the specified Hatz drive layout
- Heat, oil, and abrasion‐resistant rubber compound for long service life

Typical Applications:
Used on Hatz twin and three‐cylinder engines in equipment such as generators, water pumps, compressors, compactors, lighting towers, and site welders. Ideal for routine maintenance and scheduled belt replacement to restore correct drive function and maintain charging, cooling, and auxiliary systems.
