The Genie 1276742GT is a genuine OEM Isuzu Tier 4 V-Belt designed for AL5 light towers, including AL5 units equipped with a vertical mast configuration. As a direct OEM component, this belt is matched to the Isuzu Tier 4 engine specifications used in these machines, ensuring a proper fit without guesswork or modification. Cross-reference part number 1276742GT against your parts manual to confirm applicability for your specific unit before ordering.
Key Features
- Genuine OEM Engine Match — Sourced directly from Genie as an OEM part, this belt is spec'd to the Isuzu Tier 4 engine's drive geometry, meaning correct tension, pulley contact, and load rating right out of the box.
- Direct Drop-In Fitment — Engineered to seat on the existing pulley arrangement of the AL5 engine drive system, this belt installs without alteration to mounts or tensioners.
- AL5 Light Tower Compatibility — Fits Genie AL5 light towers, covering both standard and vertical mast variants of this model line.
- Sustained Power Delivery — A properly tensioned, unworn drive belt keeps the Isuzu engine's alternator and accessories spinning at the correct speed, supporting consistent electrical output for the light tower's lamps and generator systems.
- Operational Safety — On a generator-driven light tower, a slipping or broken drive belt can cause sudden loss of power to lighting systems on an active worksite — replacing a worn belt on schedule keeps the machine operating safely and predictably.
A V-belt transfers rotational power from the engine's crankshaft pulley to driven accessories such as the alternator, cooling fan, or hydraulic pump, depending on the drive arrangement. The belt's V-shaped cross-section grips the pulley grooves under tension, allowing efficient power transfer without slippage. Over time, heat cycling, oil contamination, and normal wear cause the belt material to crack, glaze, or stretch — a worn belt will slip under load, reducing output from driven components, and a snapped belt will shut down those systems entirely until replaced.
