Wacker Neuson 5000071648 Piston Pin

The Wacker Neuson is a genuine OEM Piston Pin designed for a broad range of Wacker Neuson equipment, including CT36 and CT30 walk-behind concrete trowels, WP and VP series single-direction vibratory plates, BPU reversible vibratory plates, PT2A centrifugal trash pumps, GP and GV portable generators, and several screed power units. This is a direct OEM replacement sourced through authorized Wacker Neuson supply channels, ensuring it meets the exact dimensional and material specifications of the original part. Fitment spans a wide cross-section of the Wacker Neuson lineup — from compaction and concrete finishing to pumping and power generation — so always verify your model number and machine number before ordering. With confirmed against your unit, you can install with confidence that the part will perform as the engine was designed to deliver.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact bore diameter and surface hardness specifications, ensuring correct wrist-pin clearance within the connecting rod and piston assembly.
• Drop-In Engine Compatibility — Engineered to seat directly into the OEM piston and rod without machining or fitting adjustments across all covered models.
• Wide Cross-Platform Fitment — A single part number covers CT30/CT36 trowels, WP/VP/BPU compaction plates, PT2A trash pumps, GP/GV generators, and HP/SP screed power units — one SKU for multiple machines sharing the same engine platform.
• Critical Engine Integrity — A worn or out-of-spec piston pin causes piston slap, increased blowby, and accelerated cylinder wear; replacing it promptly restores proper combustion transfer and protects the engine block.
• Fuel System Safety Compliance — As a pressurized combustion component, using the correct OEM-spec pin prevents abnormal play in the piston assembly that could lead to misfiring or uncontrolled engine behavior under load.

The piston pin — also called a wrist pin — is the hardened steel pin that links the piston to the small end of the connecting rod inside the engine cylinder. It allows the connecting rod to pivot as the piston travels up and down, transferring the force of combustion into rotational motion at the crankshaft. Because it operates under continuous high-load cycling and elevated heat, the pin must maintain tight dimensional tolerances; if it wears oversize or develops surface pitting, it creates play in the piston assembly that causes knocking, loss of compression, and rapid internal engine damage. Replacing a worn piston pin with a correctly spec'd OEM part like the 5000071648 restores the tight fit the engine requires to run cleanly and efficiently.
