The Genie 80121GT is a genuine OEM Exhaust Manifold Stud, M8X1.25X45 designed for TML-4000 and TML-4000N light towers. As a factory-sourced component, this stud is manufactured to the same dimensions and material grade as the original, ensuring a correct, secure fit in the exhaust manifold mounting position. Cross-reference part number 80121GT against your machine's parts manual to confirm it is the right stud for your specific unit before ordering.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact M8X1.25X45 thread and length specifications, matching the original stud for proper torque and sealing at the exhaust manifold joint.
- Direct Exhaust Manifold Replacement — Threads directly into the manifold mounting position with no modification, restoring a secure, leak-free connection between the manifold and the engine.
- Confirmed Fitment for TML-4000 Series — Sourced specifically for the TML-4000 and TML-4000N Terex mobile light towers, so you can order with confidence for those units.
- Exhaust Integrity Maintained — A sound manifold stud holds the exhaust manifold firmly in place, preventing exhaust leaks that can affect engine performance, introduce harmful gases into the work area, and accelerate wear on surrounding components.
- Operational Safety — A failed or missing exhaust manifold stud allows exhaust gases to escape at the manifold face. Replacing a damaged stud promptly keeps the exhaust circuit sealed and the light tower operating safely on the jobsite.
An exhaust manifold stud is a threaded fastener that anchors the exhaust manifold to the engine, holding it tightly against a gasket to contain and direct exhaust gases away from the engine. When a stud stretches, corrodes, or breaks, the manifold can work loose, allowing exhaust gases to leak at the joint — a condition that can damage the gasket, stress adjacent hardware, and create a hazard for anyone working near the machine. Replacing a worn or broken stud with the correct OEM part restores the clamping force the manifold needs to seal properly and stay in place through the heat cycles of normal operation.
