The Wacker Neuson 5100026422 is a genuine OEM Crankcase designed for the DPU110L and DPU110rL series reversible vibratory plate compactors. As a direct factory replacement, this crankcase is manufactured to the exact specifications required by Wacker Neuson for use across the full DPU110 platform, including Lec, Lem, Lekc, and US-market variants spanning the 870 and 970 generations. Sourcing a genuine OEM component like the 5100026422 ensures the part integrates correctly with the engine assembly without dimensional compromise. With verified fitment across more than a dozen DPU110 configurations, this is the correct crankcase to specify when rebuilding or replacing the lower engine structure on your machine.
Key Features
- Genuine OEM Casting Integrity — Manufactured by Wacker Neuson to the same material grade and dimensional tolerances as the original, ensuring proper bore geometry and sealing surface condition critical to crankcase function.
- Direct Engine Assembly Fit — Designed to accept the original crankshaft, bearings, and seals without reworking mounting points or gasket surfaces, supporting a clean, complete engine rebuild.
- Broad DPU110 Series Coverage — Confirmed fitment across DPU110Lec, DPU110Lem, DPU110Lekc, DPU110rLec, and DPU110rLem variants in both standard and US-market configurations, across 870 and 970 generations.
- Structural Foundation for Engine Performance — A correctly sealed and undamaged crankcase maintains proper oil retention and bearing support, allowing the compactor's engine to deliver full power output to the exciter system.
- Fuel and Oil System Integrity — As a primary engine enclosure, a genuine OEM crankcase with correct sealing surfaces prevents oil leaks that can lead to lubrication loss and premature internal engine wear — a critical consideration on high-vibration compaction equipment.
The crankcase is the structural core of the engine, forming the sealed housing that encloses the crankshaft, connecting rod, and lower-end bearings while retaining the engine oil needed to lubricate all moving components. On reversible vibratory plate compactors like the DPU110 series, the engine operates under sustained mechanical stress from both combustion forces and exciter-generated vibration, making crankcase integrity essential to engine longevity. When a crankcase develops cracks, stripped threads, or damaged sealing surfaces, oil retention is compromised, internal components lose proper lubrication, and catastrophic engine failure can follow — making timely replacement with the correct OEM part the only reliable fix.
