The Genie 52258GT is a genuine OEM Spindle Washer designed for a broad range of Genie and Terex trailer-mounted articulating booms and mobile light towers, including the TML-4000, TML-4000N, TZ-34/20, TZ-50, TZ-50/30, TMZ-17/10, TMZ-34/19, and TMZ-50/30. Sourced directly from Genie, this washer is an exact-fit OEM component that installs without modification, preserving the precise tolerances the original assembly was engineered around. Cross-reference part number 52258GT against your machine's parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original material and dimensional specifications, ensuring the washer seats and loads correctly within the spindle assembly.
- Direct Drop-In Replacement — Matches the original mounting profile for a straightforward swap with no rework needed on the surrounding hardware.
- Broad Model Coverage — Fits Genie and Terex trailer-mounted articulating boom lifts (TZ and TMZ series) as well as TML-series mobile light towers, making it a versatile service part across multiple equipment lines.
- Maintains Spindle Integrity — A correctly fitted washer distributes load evenly across the spindle interface; a worn or missing washer can allow metal-on-metal contact, accelerating wear to surrounding components.
- Safe Rotation and Alignment — On trailer-mounted and towable equipment, proper spindle hardware is critical to consistent wheel tracking and towing stability — keeping the unit operating as intended on and off the jobsite.
A spindle washer sits between rotating or sliding spindle components, acting as a load-distributing interface that prevents direct surface contact between mating parts. By cushioning and spreading axial loads, it reduces wear on the spindle and the components it bears against, helping the assembly move smoothly and consistently. When a spindle washer deteriorates or is missing entirely, uneven loading can cause premature wear, increased play in the assembly, and potential misalignment — issues that are especially consequential on towable equipment where wheel and axle integrity directly affects safe road transport.
