The Wacker Neuson Nut is a genuine OEM component designed for PT6Y and PT6YT series pumps. Sourced directly from Wacker Neuson, this replacement nut meets the exact material and dimensional specifications of the original hardware used on these machines. Compatible across multiple PT6Y variants — including the PT6Y-SA, PT6YT, PT6Y-AU, and PT6YT-IN — this is the correct factory part for scheduled maintenance or field repairs. Having the right hardware on hand keeps your pump assembly properly secured and operating as intended.
Key Features
- Genuine OEM Hardware Spec — Manufactured to the exact thread form, hardness grade, and dimensional tolerances specified for the original assembly — no guesswork on fitment.
- Drop-In Replacement — Installs directly in place of the original nut with no reworking of mating threads or fastener seats required.
- Broad PT6Y Series Coverage — A single part number covers PT6Y-SA, PT6YT, PT6Y-AU, PT6YT-IN, and standard PT6Y configurations, making it a practical stocking choice for fleets running multiple variants.
- Maintains Clamping Integrity — A correctly spec'd nut holds critical pump components at the right torque value; an undersized or incorrect substitute can loosen under vibration and lead to assembly failure.
- Verified Wacker Neuson Part Number — Part number 5100071031 is confirmed against Wacker Neuson parts documentation, so you can order with confidence that you're receiving the right component.
A nut is a fundamental threaded fastener that works in conjunction with a bolt or stud to clamp and secure machine components together. In pump assemblies, fasteners like this one are critical to keeping housings, covers, and mechanical elements properly aligned and torqued — preventing movement, vibration-induced loosening, and potential fluid or mechanical failure. When a nut becomes stripped, corroded, or damaged, replacing it promptly with the correct OEM part restores the integrity of the fastened joint and ensures the assembly performs as designed.
