The Genie 80379GT Engine Mount Isolator is a genuine OEM component designed for Genie and Terex portable light towers, including the AL4000, AL5000, AL5HT, TML-4000N, RL4, and related models. As a factory-authorized part, this isolator is built to the same specifications as the original, ensuring a direct, correct-fit replacement every time. Cross-reference part number 80379GT against your machine's parts manual to confirm it is the right fit for your specific unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original material and dimensional specifications, delivering the same grade of vibration-damping compound and mounting geometry as the part it replaces.
- Direct-Fit Replacement — Matches the original mounting configuration exactly, so installation requires no modification to the engine cradle or frame.
- Broad Light Tower Fitment — Compatible with multiple Genie and Terex light tower families, including AL4, AL4000, AL5, AL5HT, AL5000, RL4, and TML-4000N models.
- Vibration Control at the Source — A sound isolator absorbs engine vibration before it transmits into the frame, protecting surrounding components and keeping noise levels in check during extended operation.
- Operational Safety — A deteriorated or collapsed engine mount allows the engine to shift under load, risking misalignment of drive components and unplanned shutdowns on the jobsite. Replacing a worn isolator restores safe, stable engine positioning.
An engine mount isolator is a rubber-and-metal bushing positioned between the engine and the machine's frame. Its primary job is to absorb and dampen the vibration produced by the running engine, preventing that energy from transferring into the surrounding structure. Over time, the rubber element can harden, crack, or collapse — when that happens, vibration increases noticeably, fasteners work loose more quickly, and the engine itself can shift out of alignment with connected components. Replacing a failed isolator with the correct OEM part restores proper engine positioning and keeps vibration at the level the machine was engineered to handle.
