Wacker Neuson 5000087871 Grease Fitting 1/4-28

The Wacker Neuson is a genuine OEM Grease Fitting 1/4-28 designed for the CRT46KHN, CRT46KHO, and CRT46ASO ride-on concrete trowels. Sourced directly from Wacker Neuson, this fitting matches the original specification for thread size and port geometry, ensuring a secure, leak-free connection to the grease pathway. It is a direct drop-in replacement for the factory-installed fitting on these CRT46 series machines, with no reworking of the grease port required.

Key Features

• Genuine OEM Thread Integrity — 1/4-28 fine-thread specification matches the original fitting exactly, maintaining proper seating and seal against grease port threads.
• Direct-Connect Replacement — Threads directly into the existing grease port on CRT46 series trowels, accepting a standard grease gun coupler for immediate use.
• CRT46 Series Fitment — Verified compatible with CRT46KHN, CRT46KHO, and CRT46ASO ride-on concrete trowels.
• Lubrication System Performance — A properly seated grease fitting ensures grease reaches critical rotating components; a damaged or missing fitting blocks lubrication flow entirely, accelerating bearing and pivot wear.
• Genuine Wacker Neuson Part — Manufactured to OEM standards, so the fitting holds up to repeated grease gun attachment without stripping or deforming the seat.

A grease fitting serves as the entry point for lubricant into a machine's grease-charged bearings, pivots, and joints. When a technician attaches a grease gun to the fitting, the one-way valve inside opens to accept grease under pressure, then closes to retain it when the gun is removed. On a ride-on concrete trowel like the CRT46 series, consistent lubrication of rotating assemblies is critical to smooth trowel arm operation and long component life. A cracked, stripped, or missing fitting prevents grease from entering the system at all, leaving bearings to run dry and wear prematurely.
