The Wacker Neuson Rectifier Assembly is a genuine OEM component designed for the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers. Sourced directly from Wacker Neuson, this assembly carries the same part number and specification as the unit installed at the factory, ensuring a drop-in fit with no guesswork on compatibility. It is an exact match for both RD27 series machines, covering the tandem roller applications where consistent electrical output is critical to reliable operation.
Key Features
- Genuine OEM Electrical Spec: — Manufactured to the original output and rectification specification, so AC-to-DC conversion stays within the precise range the RD27 charging system requires.
- Direct Plug-In Replacement: — Matches the OEM connector and mounting configuration on RD27-100 and RD27-120 machines for a straightforward swap during service.
- RD27 Series Fitment: — Confirmed fit for the RD27-100 (5000620037) and RD27-120 (5000620038) Hydrostatic Vibratory Rollers.
- Protects the Charging System: — A functioning rectifier keeps the battery charged and the roller's electrical system stable; a failed unit leads to battery drain, voltage irregularities, and unplanned stoppages on the compaction pass.
- Electrical System Safety: — Correct rectifier output prevents voltage spikes that can damage sensitive control electronics and instrumentation on the machine.
The rectifier assembly converts alternating current (AC) produced by the alternator into the direct current (DC) that charges the battery and powers the machine's electrical systems. On a tandem roller like the RD27, consistent DC supply is essential for stable operation of controls, instrumentation, and hydrostatic drive electronics. When the rectifier fails, the battery can no longer hold a charge, the machine may shut down unexpectedly mid-pass, and continued operation risks damage to downstream electrical components.
