Wacker Neuson 5000089316 Lock Nut

The Wacker Neuson Lock Nut is a genuine OEM fastener designed for a broad range of Wacker Neuson equipment, including CRT48 ride-on concrete trowels, G-Series skid-mounted and portable generators, PT3 series centrifugal trash pumps, LTW and LTV light towers, HI series indirect-fired air heaters, and WB16 power buggies. Sourced directly from Wacker Neuson, this lock nut matches the exact thread specification, material grade, and dimensional tolerances of the original hardware installed at the factory. With fitment spanning dozens of configurations across multiple product families, verifying your model number against part number before ordering is recommended. This is a stocked OEM replacement that keeps your equipment running with the correct hardware.

Key Features

• Correct Thread Engagement: — Manufactured to the exact thread pitch and diameter spec of the original, ensuring full thread engagement and proper clamping load across all listed assemblies.
• Genuine Wacker Neuson OEM Hardware: — Sourced directly from Wacker Neuson, this lock nut meets the same material and torque-retention standards as the fastener originally installed on your machine.
• Wide Cross-Family Fitment: — Compatible with CRT48 ride-on trowels, G-Series generators (G25 through G320), PT3-series trash pumps, LTW/LTV light towers, HI-series indirect-fired air heaters, and WB16 power buggies.
• Vibration-Resistant Locking Action: — A lock nut's prevailing-torque design resists loosening under vibration and dynamic loads — critical on equipment such as concrete trowels and generators that operate under sustained mechanical stress.
• Direct Drop-In Replacement: — Installs in place of the original fastener with no rework to mating hardware, maintaining the integrity of the joint and the surrounding assembly.

A lock nut is a fastener engineered to resist loosening caused by vibration, shock loads, and cyclical forces during machine operation. Unlike a standard hex nut, a lock nut incorporates a prevailing-torque feature — such as a distorted thread section or a nylon insert — that maintains clamping force even as the machine vibrates or flexes in use. When a lock nut loosens or fails, connected components can shift, create play in the assembly, or detach entirely, which can lead to accelerated wear of surrounding parts or a machine-out-of-service condition. Replacing a worn or missing lock nut with the correct OEM part, such as the Wacker Neuson 5000089316, restores the designed clamping integrity and keeps critical joints properly secured.
