The Genie 75399GT is a genuine OEM Flat Washer, M14, Deutz F4L913 designed for Genie S-series telescopic boom lifts and Z-series articulating boom lifts powered by the Deutz F4L913 engine, including the S-80, S-85, S-100, S-105, S-120, S-125, and Z-80/60. Sourced directly from Genie, this replacement washer matches the original specification exactly, ensuring it seats and torques correctly within the engine assembly. Cross-reference part number 75399GT against your machine's parts manual to confirm fitment before ordering.
Key Features
- OEM-Grade M14 Dimensioning — Manufactured to the precise outer diameter, inner diameter, and thickness required by the Deutz F4L913 engine, so load is distributed evenly across fastened surfaces without distortion.
- Direct Drop-In Replacement — This washer installs in the same position as the original, requiring no modification to hardware or mating surfaces.
- Broad Boom Lift Compatibility — Fits Genie S-series telescopic booms (S-80 through S-125) and the Z-80/60 articulating boom lift, all equipped with the Deutz F4L913 engine.
- Protects Critical Fastener Joints — A correctly sized washer prevents fastener pull-through and surface galling, maintaining clamp load integrity on engine-mounted components over time.
- Engine System Integrity — On aerial work platforms, secure and properly torqued engine hardware is essential to safe machine operation at height; using the correct OEM washer helps ensure that joint integrity is not compromised.
A flat washer serves as a load-distributing interface between a fastener — typically a bolt or nut — and the surface it bears against. By spreading clamping force over a wider area, it prevents the fastener head or nut from embedding into or damaging the mating surface, and it helps maintain consistent torque retention over time. On engine assemblies such as the Deutz F4L913, using a washer with the correct M14 bore and outer dimensions is critical; an undersized or oversized washer can allow fasteners to work loose under vibration, leading to leaks, component movement, or accelerated wear on surrounding hardware.
