The Genie 8887GT is a genuine OEM External Star Washer,.5 designed for a wide range of Genie equipment, including S-series telescopic boom lifts, TML light towers, AWP personnel lifts, and Load Lifter material lifts. As a factory-sourced component, this washer matches the exact material grade, tooth count, and outside diameter specified for original Genie assemblies. Cross-reference part number 8887GT against your parts manual to confirm the correct application before ordering. Compatible models include the S-60, S-60 XC, S-60 HC, S-60 TRAX, S-60X, S-65, S-65 TRAX, TML-4000N, AWP series, Load Lifter, and PLC PLI personnel-lift lines.
Key Features
- Genuine OEM Hardened Teeth — The external serrations are formed to OEM specification, biting into mating surfaces to lock fasteners against vibration-induced loosening in field conditions.
- Direct Drop-In Hardware — The .5 outside dimension matches the original fastener stack exactly, so this washer seats without shimming or modification to the surrounding hardware.
- Broad Cross-Fleet Compatibility — Fits Genie S-series telescopic booms, TML light towers, AWP push-around personnel lifts, Load Lifter material lifts, and PLC PLI units, making it a practical stocking item for mixed fleets.
- Vibration Resistance Where It Counts — On aerial equipment and light towers subject to constant engine vibration and travel loads, an external star washer is the last line of defense against fastener back-out — a worn or missing washer can lead to loose electrical grounds, panel hardware, or structural connections.
- Electrical Grounding Integrity — Star washers are commonly used at grounding points; the serrated teeth cut through surface oxidation to maintain a low-resistance electrical path, making this a safety-relevant component on powered equipment.
An external star washer functions by biting into the face of a mating surface and the underside of a fastener head simultaneously, creating a mechanical lock that resists rotation caused by vibration and dynamic loading. On Genie booms, personnel lifts, and light towers — machines that encounter engine vibration, travel over rough terrain, or cycle through repeated extension and retraction — keeping fasteners torqued and seated is essential to structural and electrical integrity. When this washer is missing, damaged, or flattened from overtorque, the fastener it secures is far more likely to back out, potentially compromising a ground connection, a panel mount, or a structural joint.
