The Genie 1266730GT Sleeve Stem Seal is a genuine OEM engine seal designed for the Genie RL4 Vertical Mast light tower. Sourced directly from Genie and engineered to Kohler's exact specification, this seal delivers the precise fit and material integrity that the original design demands. Cross-reference part number 1266730GT against your parts manual to confirm compatibility before ordering.
Key Features
- Kohler-Spec Sealing Material — Genuine OEM construction meets the exact compound and dimensional spec Kohler requires for this stem application, ensuring proper compression and long-term sealing performance.
- Direct Engine Drop-In — Engineered to seat correctly in the valve stem bore without reworking surrounding components, making this a straightforward engine service part.
- Fits the RL4 Vertical Mast — Confirmed fitment for the Genie RL4 light tower, so you can order with confidence for that specific unit.
- Protects Engine Integrity — A correctly seated stem seal keeps oil out of the combustion chamber and combustion gases out of the valve train, preserving compression and preventing oil consumption.
- Critical for Engine Rebuild Accuracy — When performing a valve job or top-end overhaul on the Kohler engine, using the correct OEM seal is essential to restoring the engine to proper operating condition and avoiding repeat failures.
A sleeve stem seal, sometimes called a valve stem seal, fits around the valve stem where it passes through the cylinder head, forming a controlled barrier between the oil-lubricated valve guide and the combustion chamber. Its job is to meter the small amount of oil needed to lubricate the valve stem while preventing excess oil from being drawn into the cylinder, which would cause blue exhaust smoke, fouled plugs, and rising oil consumption. When this seal hardens, cracks, or wears out, oil makes its way past the valve stem unchecked — leading to carbon buildup, loss of compression, and accelerated wear throughout the top end of the engine. Replacing it with the correct OEM part restores the engine's designed sealing geometry and keeps the Kohler powerplant on your RL4 running cleanly.
