The Wacker Neuson Cylinder with Piston is a genuine OEM assembly designed for the RD7H tandem roller and DPU 4045H and DPU 5045H reversible vibratory plate compactors. As a direct OEM part sourced through authorized Wacker Neuson supply channels, the delivers the dimensional accuracy and material specification required to restore proper engine or hydraulic function in demanding compaction applications. This assembly is confirmed to fit the RD7H double drum vibratory roller alongside the DPU 4045H and DPU 5045H reversible plate compactor models, covering both the standard and 750-series machine configurations. When you need a like-for-like replacement that meets original build tolerances, this is the correct part for the job.
Key Features
- Genuine OEM Bore and Wall Tolerances — Manufactured to Wacker Neuson's original dimensional specifications, ensuring correct compression characteristics and a proper mating fit with associated piston rings and cylinder head components.
- Complete Cylinder and Piston Assembly — Supplied as an integrated unit, so the cylinder bore and piston are matched at the source — eliminating the guesswork of pairing separate components during a rebuild.
- Broad Compaction Equipment Fitment — Compatible with the RD7H double drum vibratory roller and both the DPU 4045H and DPU 5045H reversible vibratory plate compactors, including 750-series variants.
- Restores Full Power Output — A worn or scored cylinder causes loss of compression, rough running, and reduced compaction force. Replacing with 5000104345 brings the engine back to its rated output so your machine delivers consistent compaction energy.
- Fuel System and Emission Integrity — A correctly sealed cylinder assembly maintains the combustion efficiency the engine was calibrated for, supporting proper fuel burn and keeping exhaust output within expected parameters.
The cylinder with piston is the core combustion assembly of the engine — the cylinder provides the bore in which the piston travels, and together they form the sealed chamber where fuel ignites and drives power to the crankshaft. On compaction equipment like vibratory plate compactors and tandem rollers, this assembly is under sustained mechanical load and high thermal cycling, making wear over time a normal service event. When the cylinder bore becomes scored or the piston loses its sealing profile, compression drops, power output falls off, and the machine can no longer deliver the compaction force it was rated for — making timely replacement critical to maintaining effective and consistent ground compaction.
