The Genie 1266645GT is a genuine OEM V-Belt designed for the Kohler KDW1003 engine as fitted to the RL4 light tower. Sourced directly from Genie, this belt matches the original specification, ensuring a correct drop-in fit on the RL4 without reworking or adapting the drive system. Genuine OEM construction means the belt profile, length, and compound are held to the same standards as the part it replaces, so the engine's accessory drive performs exactly as designed. Cross-reference part number 1266645GT against your RL4 parts manual to confirm this is the right belt for your unit before ordering.
Key Features
- Engine-Matched Belt Profile — Engineered to the Kohler KDW1003's drive geometry, delivering the correct tension, wrap angle, and load capacity for this specific engine application.
- Genuine OEM Part — Supplied by Genie to the same material and dimensional standard as the factory-installed belt, so there is no guesswork on fitment or cross-section.
- Direct RL4 Light Tower Fitment — Confirmed compatibility with the RL4 light tower equipped with the Kohler KDW1003 engine; installs in place of the original with no modifications to pulleys or mounting hardware.
- Sustained Drive Efficiency — A correctly tensioned belt keeps the alternator and ancillary components spinning at the right speed, supporting stable power output during extended light-tower operation.
- Critical Drive Component — A slipping, cracked, or worn belt can cause the alternator or cooling fan to underperform, leading to electrical output loss or engine overheating; replacing it on schedule keeps the tower running through the shift.
A V-belt transfers rotational power from the engine's crankshaft pulley to driven accessories such as the alternator and cooling fan. The belt's trapezoidal cross-section wedges into matching pulley grooves, generating the friction needed to transmit torque without slippage. Over time, heat cycling, contamination, and normal wear cause the belt to stretch, crack, or glaze — once that happens, driven accessories lose efficiency and the engine can overheat or fail to charge the battery, putting the tower out of service until the belt is replaced.
