Key Features
- Genuine OEM Dimensional Conformity — Manufactured to original Genie specifications, this pulley meets the same tolerancing and material requirements as the factory-installed component on Isuzu 4LE2-powered units.
- Direct Engine-Matched Fit — Engineered specifically for the Isuzu 4LE2 engine, this pulley installs to the correct drive configuration without modification.
- Broad AL-Series Coverage — Fits the AL5000, AL5, AL5 with Vertical Mast, and AL5HT Genie light towers, making it the right choice across the AL5 family.
- Consistent Cooling Fan Drive — A properly functioning fan pulley maintains correct belt tension and rotational speed, keeping the engine cooling system running as designed. A worn or damaged pulley can cause belt slip, uneven wear, or loss of cooling fan output.
- Backed by Genie OEM Sourcing — Supplied as a genuine Genie part through authorized distribution, giving you confidence that this part is the correct, current part for your machine.
The fan pulley is a rotating drive component mounted on the engine that transfers power from the crankshaft belt to the cooling fan. On Isuzu 4LE2-powered light towers, it ensures the fan spins at the correct speed to draw air across the engine and maintain safe operating temperatures. A pulley that is cracked, worn at the belt groove, or damaged can cause belt misalignment or slippage, reducing fan efficiency and risking engine overheating — replacing it promptly with a genuine OEM part restores proper drive function and protects the engine.
