Cross-reference part number T113783GT against your machine's parts manual to confirm it is the right fastener for your unit before ordering.
Key Features
- Genuine OEM Specification — Manufactured to Genie and Isuzu 4LE2 specification, ensuring correct thread form, dimensions, and material grade for this engine application.
- Direct Replacement Fit — Designed to replace the original fastener on the Isuzu 4LE2 exhaust manifold with no modification, using the same installation method as the part it replaces.
- Broad AL5 Family Compatibility — Fits AL5, AL5HT, AL5 with Vertical Mast, and AL5000 Genie light towers equipped with the Isuzu 4LE2 engine.
- Exhaust Integrity — A correctly torqued exhaust manifold nut keeps the manifold sealed to the engine block, preventing exhaust leaks that can affect engine performance and create hazardous fume exposure on the jobsite.
An exhaust manifold nut secures the exhaust manifold to the engine block, maintaining a tight, leak-free seal between the two mating surfaces. On a diesel engine like the Isuzu 4LE2, these fasteners are exposed to extreme heat cycling and vibration during every run cycle, which over time can cause them to loosen, corrode, or fail. A missing or damaged nut allows exhaust gases to escape at the manifold joint, which not only reduces engine efficiency but poses a serious health risk to anyone working near the unit. Replacing a worn or failed nut promptly with the correct OEM part restores the seal and keeps the engine operating as intended.
