The Wacker Neuson Gearbox Cover is a genuine OEM component designed for PDT2, PDT3, PDI2, and PDI3 series diaphragm trash pumps. Sourced directly from Wacker Neuson, this cover is an exact-match replacement for both 50mm/2in and 75mm/3in pump configurations across the PDT and PDI families. Whether you're servicing an inline or standard diaphragm model, part number is the correct factory replacement to restore your pump to full working condition. Confirmed fitment spans a wide range of PDT2A, PDT2, PDT3A, PDT3, PDI2A, PDI2, PDI3A, and PDI3 models.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional specification, ensuring the gearbox enclosure maintains a proper seal against contamination and fluid ingress.
- Direct-Fit Replacement — Matches the original mounting points and bolt pattern, dropping into place on compatible PDT and PDI series pump gearboxes without any modification to the housing.
- Broad PDT and PDI Series Coverage — Confirmed fitment across PDT2, PDT2A, PDT3, PDT3A, PDI2, PDI2A, PDI3, and PDI3A diaphragm trash pump models in both 50mm/2in and 75mm/3in discharge sizes.
- Protects Internal Drive Components — A properly fitted gearbox cover keeps debris, moisture, and pump media away from internal gear and drive components, preventing premature wear and unplanned service intervals.
- Verified Wacker Neuson Part Number — Order with confidence using part number 5000162726 — the correct OEM reference for this cover across all compatible pump variants.
The gearbox cover on a diaphragm trash pump encloses and protects the internal drive mechanism that converts engine or motor rotation into the reciprocating action that moves the diaphragm. Without a secure, undamaged cover, the gearbox is exposed to water, grit, and pumped media, which can contaminate lubricants, accelerate gear wear, and ultimately cause drive failure. A cracked, missing, or improperly seated cover is a common source of gearbox deterioration on high-cycle pump applications, making timely replacement critical to keeping the pump running at full output.
