The Wacker Neuson Gearbox Input Cover is a genuine OEM component designed for PDT3A, PDI3A, PDI3A(I), PDT2A, and PDI2A(I) series diaphragm pumps. Sourced directly from Wacker Neuson, this part matches the original specification and slots into place exactly as the factory-installed cover did. Keeping the gearbox input properly sealed is critical to pump longevity, and using the correct OEM cover ensures nothing is left to chance on the job.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original tolerances, ensuring the cover seats flush and holds a proper seal against contaminant ingress at the gearbox input.
- Direct Drop-In Replacement — Matches the original mounting pattern and hardware interface of the factory cover, so installation follows the standard service procedure without rework.
- Broad Pump Series Coverage — A single part number covers PDT3A, PDI3A, PDI3A(I), PDT2A, and PDI2A(I) diaphragm pump models, making it a convenient stocking item for mixed pump fleets.
- Protects Gearbox Input Drivetrain — A correctly fitted cover shields the input shaft area from dust, debris, and moisture that can accelerate wear on internal gearbox components and lead to premature failure.
- Verified Part Number Fit — Part number 5100075502 is confirmed against Wacker Neuson's own parts documentation for the listed models, giving you confidence you are ordering the right cover the first time.
The gearbox input cover encloses and protects the entry point of the drive gearbox on diaphragm pumps, keeping the internal gears and input shaft shielded from the working environment. Without a sound cover in place, dirt, water, and debris can work their way into the gearbox housing, wearing down gear surfaces and bearings far ahead of their normal service life. A damaged or missing cover typically shows up as increased noise from the gearbox, oil seepage around the input, or accelerated wear that shortens the pump's overall service interval.
