The Wacker Neuson Gearcase Housing is a genuine OEM component designed for the PD3B 75mm/3in Diaphragm Pump. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original, ensuring a correct installation with no guesswork. It is confirmed compatible with the PD3B series, making it a straightforward replacement for technicians and operators keeping their pump in service.
Key Features
- Genuine OEM Construction: — Cast and machined to the same dimensional tolerances as the original, ensuring internal gear components seat and align correctly within the housing.
- Direct Replacement for PD3B: — Designed to bolt directly into the PD3B 75mm/3in Diaphragm Pump drivetrain without rework or fitment adjustments.
- Protects the Drive Assembly: — Encloses and supports the gear mechanism that drives pump action, shielding moving parts from contamination and mechanical stress.
- Restores Full Pump Output: — A damaged or cracked gearcase housing allows debris ingress and misalignment that degrades diaphragm stroke consistency; replacing it restores rated flow performance.
- Verified Wacker Neuson Part Number: — Part number 5000088306 is the current OEM reference for this housing, confirmed for the PD3B platform.
The gearcase housing is the structural enclosure that surrounds and protects the gear-driven mechanism responsible for actuating the pump's diaphragm. It maintains precise alignment between the drive shaft, gears, and diaphragm linkage, which is critical for consistent fluid displacement and rated pump output. When the housing is cracked, worn, or damaged, internal components lose their alignment, lubrication escapes, and contamination enters — leading to accelerated wear of the gear set and erratic or failed pumping action.
