The Genie 990230GT Flat Washer, 3/4 ZP is a genuine OEM fastener component built for Genie and Terex AL- and RL-series light towers, including the AL4000, AL5000, AL4, AL5, AL5HT, RL4000, and RL4. As a direct OEM replacement, this washer is manufactured to the same dimensional and material standards as the original part. Cross-reference part number 990230GT against your machine's parts manual to confirm it is the correct item for your unit.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to exact Genie specifications, ensuring the correct outer diameter, inner diameter, and thickness for a proper fit with 3/4-inch fastener assemblies.
- Direct OEM Replacement — Installs in place of the original washer with no modification, maintaining the integrity of the fastened joint.
- Broad Light Tower Fitment — Fits multiple Genie and Terex AL- and RL-series portable light towers, including AL4000, AL5000, AL5HT, RL4000, and RL4 models.
- Correct Load Distribution — A properly sized flat washer spreads clamp load evenly across the mating surface, protecting the joint and the component being fastened from damage over time.
A flat washer distributes the clamping force of a bolt or nut across a wider surface area, preventing the fastener from pulling through or damaging the material it secures. Without the correct washer in place, fasteners can loosen prematurely or cause surface damage to structural and panel components. On light tower equipment that is regularly transported and set up in the field, maintaining secure fastener assemblies with properly rated hardware keeps the unit in reliable working condition.
