The Bomag 83670305 Potentiometer is a genuine OEM component designed for BM 1200/30 and BM 1300/30 cold milling machines. Sourced directly from Bomag, this potentiometer delivers the exact electrical resistance characteristics and mechanical fit the machine's control system requires. It is a direct replacement for the original unit on both the BM 1200/30 and BM 1300/30, ensuring seamless integration with existing wiring and control circuits. Operators who need to restore precise positional sensing or throttle feedback can rely on this part to bring the machine back to correct operating specification.
Key Features
- OEM-Matched Resistance Output — manufactured to the same resistance tolerances and signal range as the original, ensuring the control system reads accurate positional data without recalibration.
- Drop-In Electrical and Mechanical Fit — matches the original connector pinout, shaft dimensions, and mounting configuration on BM 1200/30 and BM 1300/30 cold milling machines for a straightforward swap.
- Confirmed Cold Milling Machine Fitment — verified for the Bomag BM 1200/30 and BM 1300/30, covering both models in this milling machine series.
- Restores Accurate Machine Control — a worn or drifted potentiometer causes erratic throttle response or inaccurate position feedback; replacing this component brings control system performance back to spec.
- Genuine Bomag OEM Part — part number 83670305 is an authentic Bomag component, carrying the same design and material standards as the part it replaces.
A potentiometer is a variable resistor that sends a continuously changing electrical signal to the machine's control unit, communicating the position of a lever, pedal, or actuator. On Bomag cold milling machines, this signal is critical for functions such as engine throttle control or rotor depth adjustment — the control unit reads the potentiometer's output to determine exactly where an operator-controlled input is set. When a potentiometer wears out or fails, the signal becomes inconsistent or falls out of the expected range, which can cause sluggish response, erratic behavior, or fault codes that prevent the machine from operating correctly. Replacing a faulty potentiometer with the correct OEM unit restores clean, accurate signal transmission and dependable machine response.
