The Wacker Neuson 5100039328 Crankcase Cover Complete is a genuine OEM component designed for PT4A and PT4A(I) series self-priming centrifugal trash pumps. As a direct OEM replacement, this cover is manufactured to the same specifications as the original part, ensuring a proper seal and correct fitment without additional machining or adaptation. This assembly is confirmed compatible across multiple PT4A configurations, making it a straightforward service solution for field technicians and shop mechanics alike. Keep part number 5100039328 on hand to minimize unplanned service interruptions on your Wacker Neuson PT4A equipment.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional standards, ensuring the crankcase is fully sealed against oil leaks and contaminant ingress.
- Drop-In Assembly Fit — Supplied as a complete cover assembly, this unit installs directly onto the crankcase mating surface with no additional sub-assembly or fitment adjustment needed.
- Confirmed PT4A and PT4A(I) Compatibility — Verified fitment across PT4A and PT4A(I) trash pump models, covering multiple serial-range configurations within the PT4A family.
- Protects Internal Engine Components — A sound crankcase cover maintains proper oil retention and crankcase pressure; a cracked or failed cover can lead to rapid oil loss and accelerated engine wear.
- Sourced Direct from Wacker Neuson — Part number 5100039328 is an authorized OEM component, supporting accurate parts documentation and service record compliance.
The crankcase cover seals the lower end of the engine, enclosing the crankshaft, bearings, and oil supply within a protected environment. It maintains correct crankcase pressure and prevents oil from escaping while keeping dirt, water, and debris away from critical rotating components. When the crankcase cover cracks, warps, or develops a failed gasket surface, oil leaks and pressure loss follow quickly, putting the engine at risk of serious internal damage if the pump continues to operate.
