The Wacker Neuson Crankcase is a genuine OEM component designed for the RD7H-ES and RD7H-S tandem rollers and the DPU 4045H and DPU 5045H reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this crankcase matches the exact specifications of the original part, ensuring a correct fit without modification. It is compatible across multiple configurations of the RD7 tandem roller series as well as the DPU 4045H and DPU 5045H diesel reversible plate lines. When engine integrity is on the line, replacing a damaged or worn crankcase with a genuine OEM part is the only way to protect the rest of the drivetrain.
Key Features
- Genuine OEM Casting Integrity — Manufactured to Wacker Neuson's original tolerances, ensuring correct bore geometry and sealing surface quality critical for crankcase function.
- Direct-Fit Replacement — Matches original mounting points, gasket surfaces, and port locations for a straightforward swap on covered machines.
- Broad Model Coverage — Fits RD7H-ES and RD7H-S tandem roller variants as well as DPU 4045H and DPU 5045H diesel reversible vibratory plate compactors across multiple machine configurations.
- Protects Engine Assembly — A correctly sealed crankcase maintains proper oil retention and bearing support; a cracked or compromised housing leads to oil loss, bearing failure, and costly collateral engine damage.
- Fuel and Oil System Integrity — Correct crankcase fitment is essential to maintaining proper crankcase pressure and preventing seal blowouts or fuel contamination in the lower engine assembly.
The crankcase forms the structural foundation of the engine, housing the crankshaft, connecting rod, and lower bearing assemblies while containing the engine oil needed to lubricate those moving parts. It must maintain a precise sealed environment to sustain correct crankcase pressure and prevent oil from escaping into surrounding components. When a crankcase is cracked, warped, or worn at its sealing surfaces, it typically causes persistent oil leaks, loss of crankcase pressure, and accelerated wear on bearings and seals — failures that can quickly escalate into full engine replacement if not addressed.
