The Multiquip 01679100 Crankcase Assembly is a genuine OEM component designed for MVH406, QP4TZ, and MVH-406DSZ series equipment. Sourced directly from Multiquip, this assembly meets the exact specifications of the original part and installs as a direct replacement with no rework required. Whether you're servicing a heavy-duty reversible plate compactor or a trash pump, the part restores the engine's structural foundation to factory condition. Confirm your model number before ordering to ensure a correct match.
Key Features
- Genuine OEM Construction — Machined to the same tolerances as the original, ensuring correct bore alignment, bearing seat dimensions, and sealing surfaces critical to crankcase integrity.
- Direct-Fit Assembly — Replaces the original crankcase housing with matching bolt patterns and port locations, so installation follows the standard service procedure without custom fitting.
- Broad Model Coverage — Compatible with MVH406, QP4TZ, and MVH-406DSZ equipment, covering both heavy-duty reversible plate compactor and trash pump applications in the Multiquip lineup.
- Engine Structural Integrity Restored — A damaged or worn crankcase leads to oil leaks, bearing failure, and loss of compression; replacing it with a genuine assembly brings the engine block back to its designed operating condition.
- Fuel System Sealing Compliance — As a core engine housing component, the part provides the sealed environment required for safe containment of oil and combustion gases, directly supporting fuel system and emissions integrity.
The crankcase assembly forms the structural core of the engine, housing the crankshaft, bearings, and internal oil passages that keep all moving components lubricated and in alignment. It must maintain a precise, oil-tight seal to support correct oil pressure and prevent contamination of the combustion chamber. When a crankcase develops cracks, stripped threads, or worn bearing bores, the entire engine is at risk — oil loss accelerates wear across every internal component, and continued operation can lead to catastrophic engine failure. Replacing the assembly with a genuine Multiquip part ensures the engine returns to its original structural specification.
