The Wacker Neuson Crankcase Cover Gasket is a genuine OEM crankcase cover gasket designed for MDP3 and PT3c series diaphragm and trash pumps. Sourced directly from Wacker Neuson, this is the same part installed at the factory — ensuring a correct, leak-free seal without guesswork. It is compatible across the MDP3, MDP3X, MDP3-CN, PT3G-c CE, and PT3G-c CN model variants. When it comes to crankcase sealing, using the OEM-specified gasket is the straightforward way to protect the engine and keep the pump running as intended.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's exact material and compression specifications, delivering a consistent, oil-tight seal at the crankcase cover interface.
- Drop-In Crankcase Cover Fit — Matches the original gasket profile precisely, seating flush against the crankcase cover mating surface with no trimming or reworking required.
- Broad MDP3 and PT3c Series Coverage — A single part number covers MDP3, MDP3X, MDP3-CN, PT3G-c CE, and PT3G-c CN pump variants, simplifying parts sourcing across your fleet.
- Protects Engine Integrity — A properly sealed crankcase prevents oil loss and external contamination, both of which can cause accelerated internal wear and pump failure if left unchecked.
- Genuine Wacker Neuson OEM Part — Part number 5000409351 is an authorized Wacker Neuson component, giving you confidence that fit and material grade match the original specification.
The crankcase cover gasket forms an oil-tight seal between the crankcase cover and the engine block, preventing lubricating oil from escaping and keeping contaminants out of the crankcase. On diaphragm and trash pumps like the MDP3 and PT3c series, maintaining this seal is critical — a failing or compressed-out gasket leads to oil seepage, loss of lubrication, and eventually internal engine damage if the problem goes unaddressed. Replacing a worn crankcase cover gasket with a correctly specified OEM part restores the seal to its original condition and prevents costly secondary damage.
