The Genie 1277636GT is a genuine OEM Main Tank Bulkhead Weldment designed for Genie S-40 and S-45 series telescopic boom lifts. As a factory-original weldment, this component is manufactured to the exact specifications required for a direct, secure installation in the hydraulic tank assembly of these machines. It is confirmed to fit the S-40 XC, S-45 XC, S-40 TRAX, S-45 TRAX, S-40 HF, and S-45 HF variants — cross-reference part number 1277636GT against your machine's parts manual to confirm compatibility before ordering. Choosing a genuine OEM part means no compromises on material grade, weld integrity, or dimensional accuracy for this structural and sealing-critical component.
Key Features
- Genuine OEM Weld Integrity — Manufactured by Genie to original engineering standards, ensuring the weld joints and formed steel meet the structural load and pressure-containment demands of the main tank bulkhead position.
- Direct-Fit Installation — Engineered to the original mounting profile and port layout, this weldment installs directly into the hydraulic tank assembly without rework or modification to mating components.
- Broad S-Series Compatibility — Fits six S-40 and S-45 telescopic boom lift variants, including XC, TRAX, and HF models, making it the correct replacement across the full range of these machines.
- Structural and Sealing Performance — The bulkhead weldment anchors fluid passages and separates tank chambers under operating pressure; a damaged or worn unit can result in hydraulic fluid leaks, loss of system pressure, and compromised boom function.
- Safety-Critical Structural Component — On a telescopic boom lift, hydraulic system integrity is directly tied to safe platform operation. Replacing a failed bulkhead weldment with a genuine OEM part restores the hydraulic containment the machine's safety systems depend on.
The main tank bulkhead weldment is a fabricated steel structural component that forms the internal dividing wall and port interface within the machine's hydraulic fluid tank. It provides a sealed boundary between fluid chambers and serves as the anchor point for hydraulic lines and fittings that route fluid to the boom's lift and drive circuits. When this weldment is cracked, corroded, or otherwise compromised, the hydraulic system can lose containment pressure, leading to external leaks, cross-contamination between tank sections, and degraded performance of the boom's lifting and extension functions. Replacing it with a genuine OEM unit restores the tank to its original sealed, structurally sound condition.
