The Wacker Neuson is a genuine OEM Connecting Rod Bush designed for the RD7H series walk-behind tandem rollers and the DPU 4045H, DPU 5045H, DPU 4545H, and DPU 5545H series diesel reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this part carries the same tolerances and material specifications as the original component installed at the factory. The is a direct-fit replacement, dropping into the connecting rod assembly without modification. With broad coverage across multiple RD7H and DPU model variants, this bush suits a wide range of serial number ranges within these two compaction equipment families.
Key Features
- Precision-Bore OEM Bushing Material — Manufactured to the exact bore diameter and bearing surface specification Wacker Neuson requires in the connecting rod assembly, maintaining correct rod-to-pin clearance throughout the service life of the engine.
- Drop-In Connecting Rod Fit — Engineered to the original press-fit dimensions for the RD7H and DPU 4045H / 5045H / 4545H / 5545H connecting rod bores, so installation follows the standard service procedure with no re-machining.
- Wide RD7H and DPU Series Coverage — A single part number covers a broad range of RD7H tandem roller variants and DPU diesel reversible plate compactor models, making it a practical stocking item for fleets running mixed Wacker Neuson compaction equipment.
- Protects Crankpin and Rod Integrity — A worn or undersized connecting rod bush accelerates wear on the crankpin journal and connecting rod bore, leading to knock, power loss, and eventual engine failure. Replacing with a correctly sized OEM bush restores proper oil film and load distribution.
- Genuine Wacker Neuson OEM Part — Part number 5000104350 is an authentic Wacker Neuson component, ensuring the material hardness, surface finish, and dimensional accuracy match the original specification for both the roller and vibratory plate engine applications.
The connecting rod bush is a small cylindrical bearing sleeve pressed into the small end of the engine's connecting rod, providing a precision wear surface between the rod and the piston pin (wrist pin). It allows the piston to pivot smoothly on the pin during each compression and power stroke while absorbing the significant side loads that combustion generates. When the bush wears, pin-to-rod clearance increases, causing audible knock, loss of compression, increased oil consumption, and — if left unaddressed — damage to the piston pin and connecting rod itself. Replacing a worn bush with a correctly sized OEM part restores the tight tolerances the engine depends on for efficient, low-vibration operation.
