Product Overview — Part 3115 1926 02
The 3115 1926 02 is a precision-manufactured Vibration Dampers component. The 3115 1926 02 is a dedicated BOMAG vibration damper rubber element for BW series compactor vibration system components. Unlike cab mounts which isolate the operator cab, this damper element is installed within the BOMAG vibration exciter system to manage internal resonances and protect the exciter assembly from fatigue. The rubber compound in part 3115 1926 02 is formulated for higher-frequency dynamic loading than cab mounts — typically 40–70 Hz continuous with peak amplitudes associated with the BOMAG eccentric mass system. Fatigue life testing demonstrates over 10 million cycles at design amplitude before significant stiffness change. Companion parts in the BOMAG vibration system include 3115 2472 00 anti-vibration mount and 3128047510 rubber isolator. All three are available with short lead times from our manufacturing facility.

Installation Guidelines
- Inspect on arrival: Verify part number 3115 1926 02. Check for transit damage — reject any non-conforming component.
- Clean mating surfaces: Remove all rust, old rubber fragments, grease, and paint before installation.
- Align correctly: Follow assembly drawing orientation. Incorrect orientation may cause premature failure.
- Torque fasteners: Use calibrated torque wrench and cross-pattern tightening sequence per OEM specification.
- Post-install check: Inspect for correct seating. Run equipment at low speed to verify no abnormal noise or vibration.
