Key Features
- Genuine OEM Construction — Manufactured to Genie's exact M8X1.25X45 thread and length specification, ensuring correct engagement with the exhaust manifold mating surface.
- Direct-Fit Replacement — Engineered to match the original fastener, dropping straight into position without modification or rework.
- TML-4000N Fitment — Confirmed fitment for the Terex TML-4000N mobile light tower; cross-reference part number 80121GT against your parts manual before ordering.
- Exhaust Integrity — A sound manifold stud holds the exhaust manifold firmly against the engine, preventing exhaust leaks that can affect engine performance and create unsafe fume exposure on the jobsite.
An exhaust manifold stud is a threaded fastener that anchors the exhaust manifold to the engine block, creating a sealed joint that channels exhaust gases away from the engine. On a light tower like the TML-4000N, the engine runs for extended periods under load, exposing manifold fasteners to repeated heat expansion and vibration that can cause studs to loosen, corrode, or fracture over time. A failed or missing stud allows exhaust gases to escape at the joint, which can reduce engine efficiency and create a safety hazard for nearby workers. Replacing a damaged stud with the correct OEM part restores the proper clamping load at the manifold and keeps the exhaust system sealed and functioning as intended.
