Wacker Neuson 5100044126 Grease Zerk

The Wacker Neuson Grease Zerk is a genuine OEM lubrication fitting designed for the Mechanical Quick Coupler (55mm). Sourced directly from Wacker Neuson, this OEM part is manufactured to the same specification as the original component installed at the factory. It is a direct-fit replacement for the Mechanical Quick Coupler (55mm), slotting into the existing grease port without any modification. Keeping this fitting in good working condition is essential to maintaining proper lubrication flow to the coupler's moving components.

Key Features

• Genuine OEM Lubrication Spec: — Manufactured to Wacker Neuson's exact thread pitch and ball-check tolerances, ensuring consistent grease flow and a leak-free seal at the fitting head.
• Direct Port Fit: — Threads directly into the existing grease port on the Mechanical Quick Coupler (55mm) for a clean, tool-standard installation.
• Confirmed Fitment: — Compatible with the Wacker Neuson Mechanical Quick Coupler (55mm), giving you confidence you're ordering the correct part the first time.
• Protects Coupler Longevity: — A functional grease zerk keeps the coupler's pivot points and wear surfaces properly lubricated, preventing premature wear and costly coupler damage.
• Verified Part Number: — Listed under Wacker Neuson part number 5100044126 for straightforward cross-referencing against your service manual or parts breakdown.

A grease zerk — also called a grease nipple or grease fitting — is a small but critical service point on equipment that relies on regular lubrication. It accepts a grease gun coupler and allows pressurized grease to be injected directly into a joint, bearing, or pivot point, displacing moisture and contaminants in the process. On a mechanical quick coupler, a damaged, seized, or missing zerk means grease cannot reach the wear surfaces, leading to accelerated metal-on-metal wear, stiff operation, and eventual coupler failure. Replacing a worn or stripped zerk promptly is one of the simplest preventive maintenance steps an operator can take to extend coupler service life.
