The Wacker Neuson is a genuine OEM Pump Arm Weldment designed for the WB16A, WB16AE, WB16AF, WB16AD, WB16AEF, WB16AES, WB16AFS, WB16AEFS, WB16ADE, WB16ADF, and WB16ADEF Power Buggy series. Sourced directly from Wacker Neuson, this part meets the same manufacturing standards as the component installed at the factory. Part number covers an extensive range of WB16 Power Buggy configurations, so buyers can confirm fitment with confidence across both early and later machine variants. If your Power Buggy's hydraulic dump system is underperforming or the existing arm shows cracking or wear at the weld joints, replacing it with the correct OEM weldment restores full lifting and dumping capacity.
Key Features
- Welded Steel Construction: — Engineered as a structural weldment, this arm is built to handle the repetitive load cycles of a hydraulic-actuated dump bed without flex or joint fatigue.
- Genuine OEM Part: — Supplied by Wacker Neuson as original equipment, 5000155067 matches the geometry and material spec of the part it replaces — no reworking or shimming needed on installation.
- Broad WB16 Series Coverage: — Fits the full WB16A Power Buggy family, including electric-start (E), forward-fold (F), and self-propelled (S) variants across multiple production series.
- Restores Full Dump Function: — A cracked or worn pump arm weldment causes loss of hydraulic leverage, resulting in slow, incomplete, or uncontrolled bed dumping. This replacement brings dump performance back to spec.
- Structural Integrity for Safe Load Handling: — Because the pump arm directly transfers hydraulic force to the dump bed, a compromised weldment poses a tipping and load-drop risk. Replacing a damaged arm is a safety-critical service step.
The pump arm weldment is the structural link between the hydraulic cylinder and the dump bed on WB16 series Power Buggies. When the hydraulic system activates, the arm transfers that force mechanically to tilt the bed and discharge the load. Because it operates under significant cyclic stress — lifting and lowering a full load repeatedly throughout the workday — the weld joints are the most common point of fatigue failure. A cracked or bent weldment reduces dumping leverage, can cause the bed to drop unexpectedly, and places additional strain on the hydraulic cylinder. Replacing part 5000155067 at the first sign of cracking or deformation keeps the dump system operating safely and prevents secondary damage to connected hydraulic components.
