The Wacker Neuson Crankshaft is a genuine OEM Crankshaft designed for the PDT2A, PDT3A, and PDI3A series. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component it replaces. Correct fitment is confirmed across all three series, making this the straightforward choice when the engine needs a crankshaft replacement.
Key Features
- OEM-Grade Journal and Bearing Surface Tolerances — Machined to the same dimensional tolerances as the original, ensuring correct oil film clearance and smooth rotation throughout the engine's operating range.
- Drop-In Engine Replacement — Engineered to the original interface dimensions, so it seats correctly in the crankcase and aligns with connecting rod, main bearings, and seals without modification.
- Confirmed Fitment for PDT2A, PDT3A, and PDI3A Series — Covers all three model series under a single part number, simplifying ordering for mixed fleets or multi-unit service jobs.
- Restores Full Power Stroke Efficiency — A worn or damaged crankshaft causes vibration, loss of compression transfer, and accelerated bearing wear; replacing it with a correctly spec'd OEM part restores smooth, consistent power delivery.
- Genuine Wacker Neuson Part — Supplied as a genuine OEM component under part number 5100056845, backed by Wacker Neuson's manufacturing standards for internal engine components.
The crankshaft is the central rotating component of a two-stroke or four-stroke engine, converting the linear force of each power stroke into the rotational output that drives the machine. It runs in precision main bearings inside the crankcase and must maintain exact dimensional tolerances to keep combustion energy transfer efficient and internal wear to a minimum. When a crankshaft develops wear, scoring, or damage — often signaled by unusual vibration, knocking, or loss of power — continued operation accelerates damage to bearings, seals, and the connecting rod, making timely replacement critical to restoring the engine to proper working condition.
