Features & Applications
High Output (135A) – Ideal for trucks, construction equipment, and heavy-duty applications. Bi-Directional (BI) Rotation – No need to worry about pulley direction. Internal Regulator (IR) – Simplified wiring, no external regulator needed. Pad Mount Design – Direct bolt-on replacement for CAT 3126, 3306, 3406, etc.
Where is it Used?
Heavy-Duty Trucks (Semi-trucks, dump trucks)
Construction Equipment (Loaders, excavators, bulldozers)
Industrial & Agricultural Machinery
Emergency Vehicles & Fire Trucks
Installation Notes
12V System Only – Do not use in 24V applications.
Check Belt Tension & Alignment – Ensures optimal performance and longevity.
Bi-Directional – Works in any rotation, but verify pulley direction for proper belt routing.
High-Amperage Draw – Ensure battery & wiring can handle 135A output.
