Wacker Neuson 5002004705 Fitting Grease Am6

The Wacker Neuson 5002004705 is a genuine OEM Grease Fitting designed for a wide range of Wacker Neuson tandem rollers, trench rollers, and concrete trowels, including the RD12, RD16, RT56, RT82, RTLx, RTKx, CRT, and CT series machines. As a factory-authorized component, the part meets Wacker Neuson's original engineering standards, ensuring a direct, drop-in fit at every grease point it serves. Confirmed fitment spans walk-behind and ride-on trowels, remote-controlled trench rollers, and tandem vibratory rollers across multiple generations of Wacker Neuson equipment. Keeping the correct grease fitting in place protects bearings, drums, and pivot points from premature wear — making this small part critical to long-term machine health.

Key Features

• Genuine OEM Construction Manufactured to Wacker Neuson's original thread form and seating geometry, so grease flows at the correct pressure without leakage or backflow at the check valve.
• Direct-Mount Replacement Threads directly into the existing port without re-tapping or adapters, restoring a fully sealed grease pathway on first installation.
• Broad Cross-Series Fitment Compatible with RD12 and RD16 tandem rollers, RT56, RT82, RTLx, and RTKx trench rollers, and the full CRT and CT concrete trowel lineup — one part number covers multiple machine families.
• Protects Critical Bearing and Pivot Points A functioning grease fitting ensures lubrication reaches drums, eccentric shafts, and articulation joints on schedule; a blocked or missing fitting accelerates metal-to-metal wear and shortens component life significantly.
• Fuel and Fluid System Safety The integrated ball-check design prevents contaminants from entering the grease circuit between service intervals, maintaining lubrication integrity in muddy or wet jobsite conditions.

A grease fitting — sometimes called a Zerk or grease nipple — is the access point through which lubricating grease is injected into a bearing housing, pivot pin, or rotating assembly using a grease gun. Inside the fitting, a spring-loaded ball check valve opens under grease-gun pressure to allow grease in, then closes to seal the port and block dirt and moisture from entering. On compaction rollers and concrete trowels, these fittings serve drum bearings, eccentric shaft housings, articulation pins, and steering pivots. When a grease fitting becomes damaged, cross-threaded, or seized, lubrication cannot be delivered to the component it serves, leading to accelerated bearing wear, overheating, and eventual component failure. Replacing a worn or missing fitting promptly with the correct OEM part — such as the Wacker Neuson 5002004705 — is one of the lowest-cost preventive maintenance steps available for protecting high-value rotating assemblies.
