The Wacker Neuson Connecting Rod is a genuine OEM connecting rod designed for a wide range of Wacker Neuson vibratory plates, truss screeds, and internal vibrators, including the WP1540A, WP1550A, VP1340A, VP1550A, VP2050A, BPU2540A, BPS series, GV2500A, and PT2A models. Sourced directly from Wacker Neuson, this part carries the same specifications as the component originally installed at the factory, ensuring a correct fit with no guesswork. It also covers compatible HP, HPG, and BT series power units, making it one of the most widely applicable engine components in the Wacker Neuson small-engine lineup. When it comes time to rebuild or restore engine performance, the is the part to reach for.
Key Features
- OEM-Spec Rod Geometry — Manufactured to the exact bore diameter, pin clearance, and bearing tolerance specified for Wacker Neuson small engines, ensuring correct compression and crank alignment on installation.
- Drop-In Engine Replacement — Matches the original rod dimensions and fastener pattern, allowing direct installation without machining or shimming.
- Broad Wacker Neuson Fitment — Covers WP1540A, WP1550A, VP1340A, VP1550A, VP2050A, BPU2540A, BPS1550A, BPS2050A, GV2500A, PT2A, HP/HPG screed power units, BT24A, BT36A, and additional variants across the Wacker Neuson vibratory and concrete equipment range.
- Engine Power Restored — A worn or damaged connecting rod causes knocking, loss of compression, and eventual engine seizure; replacing it with a correctly toleranced OEM rod restores full power output and smooth operation.
- Verified Part Number — Sold under Wacker Neuson part number 5100050571, cross-referenced against the full OEM parts catalog for confidence before you order.
The connecting rod is the mechanical link between the piston and the crankshaft inside a small engine. It converts the up-and-down movement of the piston into the rotational force that drives the crankshaft and, ultimately, the machine's working components. When a connecting rod develops excessive play at the big-end or small-end bearing journals — or suffers a fatigue crack — the result is a characteristic knock at idle that worsens under load, rapid loss of compression, and in severe cases a catastrophic engine failure. Replacing a worn rod promptly with a correctly sized OEM component is one of the most effective ways to bring an engine back to its original power and keep it running reliably through demanding compaction and concrete finishing work.
