The Wacker Neuson Crankshaft is a genuine OEM crankshaft designed for the RD7 series tandem rollers and DPU 4045H, DPU 5045H, and DPU 5545H series diesel reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this crankshaft matches the original component specification, ensuring a direct, hassle-free installation with no guesswork on fitment. It covers an extensive range of RD7 and DPU variants — including He, Heh, Hec, Hef, and Heap configurations — making it a widely applicable engine rebuild part across the RD7 and DPU heavy-duty diesel compaction families. When your machine is down for an engine overhaul or crankshaft failure, using the correct OEM part protects the integrity of the entire rebuild.
Key Features
- OEM-Matched Bearing Journal Tolerances — Machined to the exact journal dimensions required by the engine, ensuring proper bearing clearance and oil film formation throughout the crankshaft's service life.
- Drop-In Engine Replacement — Designed to install directly into the original engine block without modification to bearing caps, seals, or connecting rods on compatible RD7 and DPU models.
- Broad Fitment Across RD7 and DPU Families — Fits RD7H, RD7He, RD7Heh, RD7Hf, and related tandem roller variants, plus DPU 4045H, DPU 5045H, and DPU 5545H reversible plate compactors in standard, He, Heh, Hec, and Heap configurations.
- Protects Connected Engine Components — A correctly dimensioned crankshaft maintains proper rotation balance and prevents accelerated wear on bearings, connecting rods, and main seals — all of which are at risk when a worn or damaged crankshaft is left in service.
- Critical for Engine Integrity Under Load — In high-vibration compaction environments, crankshaft dimensional accuracy directly affects engine longevity; an out-of-spec crankshaft can cause rapid bearing failure and catastrophic engine damage.
The crankshaft is the central rotating component of a reciprocating engine, converting the up-and-down motion of the pistons into the rotational force that drives the machine. It runs in precision-machined main bearings within the engine block and connects to the connecting rods at its crankpins, making its dimensional accuracy critical to smooth, balanced engine operation. When a crankshaft becomes worn, scored, or cracked — whether from oil starvation, overloading, or age — it causes engine knocking, excessive vibration, bearing failure, and ultimately complete engine seizure if not addressed promptly.
