The Genie 1266803GT is a genuine OEM Kohler Exhaust Valve designed for the RL4 Vertical Mast light tower. Sourced directly from Genie, this part meets the exact engineering specifications required for proper engine valve operation on the RL4. Genuine OEM designation means this exhaust valve is the same component fitted at the factory, ensuring a direct, correct-fit installation. Cross-reference part number 1266803GT against your Genie parts manual to confirm fitment for your specific unit before ordering.
Key Features
- OEM-Matched Valve Geometry — Manufactured to the same dimensional and metallurgical standards as the original Kohler component, ensuring correct sealing surface contact and heat dissipation in the exhaust cycle.
- Direct Engine Replacement — Engineered to drop into the Kohler engine on the RL4 Vertical Mast without modification, maintaining correct valve timing and seat alignment.
- RL4 Light Tower Fitment — Confirmed for the Genie RL4 Vertical Mast, the portable towable light tower powered by a Kohler engine, making this the right part for that specific application.
- Sustained Engine Output — A properly functioning exhaust valve allows spent combustion gases to exit cleanly and on schedule, keeping the engine running efficiently to power the light tower's generator through long overnight shifts.
- Engine Integrity and Operational Safety — A worn or burnt exhaust valve causes compression loss, rough running, and potential engine damage. Replacing with a genuine OEM part restores proper combustion sealing and protects the engine from further harm.
The exhaust valve is a critical engine component responsible for opening and closing the exhaust port in the cylinder head at precisely timed intervals. During each combustion cycle, it opens to allow burnt exhaust gases to escape the cylinder before closing tightly to seal the chamber for the next intake stroke. When an exhaust valve wears, warps, or burns through — often from heat or carbon buildup — it can no longer form a proper seal, leading to compression loss, misfiring, reduced power output, and accelerated engine wear. Replacing a failed exhaust valve promptly restores full compression, smooth engine operation, and the reliable generator output that a light tower like the RL4 depends on for extended jobsite use.
