- Direct OEM Replacement — Engineered to match the original mounting configuration and connector interface, this Generator / Alternator installs in place of the factory unit without modification.
- Confirmed Fitment — Verified for Bomag BW 850 TR and BW 85 T trench compactors, so you can source with confidence.
- Charging System Integrity — A functioning alternator keeps the battery charged and the electrical system stable; a worn or failed unit can cause erratic machine behavior, starting failures, and unplanned stoppages.
- Electrical Safety Compliance — As a genuine OEM part, this alternator maintains the correct grounding and output protection characteristics specified for these machines, supporting safe electrical system operation.
The Generator / Alternator is responsible for continuously recharging the battery and supplying electrical power to the machine's systems while the engine is running. On trench compactors like the BW 850 TR and BW 85 T, a healthy alternator is critical to sustaining reliable engine starts and consistent operation of controls and lighting. When the alternator weakens or fails, the battery discharges, electrical components become erratic, and the machine may shut down entirely — making prompt replacement essential to keeping the compactor productive.
