The Wacker Neuson Crank is a genuine OEM component designed for the PDT2A, PDI2A, PDT2, and PDI2 series 50mm/2in diaphragm trash pumps. Sourced directly from Wacker Neuson, this crank meets the original design specification for these compact, portable pumping units. Compatible across both standard and inline diaphragm pump configurations, the is the correct replacement when the original crank shows wear or requires service. Confirm your model number before ordering to ensure a direct fit.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original dimensional and material tolerances, ensuring the crank engages the diaphragm drive mechanism with the correct stroke geometry.
- Direct Drop-In Replacement — Matches the original mounting configuration for the PDT2A, PDI2A, PDT2, and PDI2 pump families, fitting into the existing crank housing without modification.
- Broad PDT2/PDI2 Series Coverage — Confirmed fitment across multiple build variants of the 50mm/2in diaphragm trash pump line, including standard and inline pump models.
- Consistent Diaphragm Stroke — A correctly functioning crank delivers the precise reciprocating motion the diaphragm needs to maintain rated flow and suction performance; a worn crank causes erratic pumping or complete loss of prime.
- Verified OEM Part Number — Part number 5000089601 is the authoritative Wacker Neuson reference for this crank, eliminating guesswork when sourcing a like-for-like replacement.
The crank is a core mechanical component inside a diaphragm pump's drive assembly. It converts the rotational motion of the engine or motor into the back-and-forth movement that flexes the diaphragm, drawing fluid in on one stroke and pushing it out on the next. Without a correctly functioning crank, the diaphragm cannot complete its full stroke, leading to reduced flow rate, loss of prime, or a complete pumping failure. Replacing a worn or damaged crank restores the pump's designed fluid transfer capacity and keeps the unit operating at its rated output.
