The Bomag 05902389 Gear Unit for Travel is a genuine OEM component designed for BW 174 and BW 170 series tandem rollers, including the BW 174 AD-2, BW 174 AD-2 AM, BW 174 AC-2, BW 174 AC-2 AM, BW 174 AP, BW 174 AP-AM, BW 174 ACP, BW 174 ACP-AM, BW 170 AD-2 AM, and BW 170 AP AM. Sourced directly from Bomag, this gear unit matches the original component exactly, ensuring correct integration with the roller's travel drive system. Confirming part number 05902389 against your machine's serial plate and service documentation before ordering is always recommended.
Key Features
- Genuine OEM Gear Tolerancing — manufactured to Bomag's original specifications, with gear geometry and bearing interfaces that match the travel drive assembly precisely, maintaining correct torque transmission and minimizing internal wear.
- Direct Drop-In Replacement — mounts to the existing drive interface on BW 174 and BW 170 series tandem rollers without reworking mounting points or adapting fastener patterns.
- Broad BW 174 and BW 170 Series Coverage — confirmed fitment across the BW 174 AD-2, BW 174 AD-2 AM, BW 174 AC-2, BW 174 AC-2 AM, BW 174 AP, BW 174 AP-AM, BW 174 ACP, BW 174 ACP-AM, BW 170 AD-2 AM, and BW 170 AP AM tandem rollers.
- Consistent Travel Drive Performance — a properly functioning travel gear unit delivers smooth, controlled drum propulsion at the correct speed and torque ratio; a worn or failed unit can cause erratic travel, loss of traction, or complete drive failure on the asphalt.
- Authenticated Bomag Part — supplied as a genuine Bomag assembly, so the part number 05902389 traces directly back to Bomag's own supply chain with no substitution in materials or heat treatment.
The gear unit for travel is a core element of a tandem roller's propulsion system, transferring power from the hydraulic or mechanical drive source to the drum to move the machine forward and in reverse across the paving surface. It steps down rotational speed and multiplies torque to deliver the controlled drum movement that asphalt compaction requires. When this unit develops internal wear, gear damage, or bearing failure, the result is typically sluggish or uneven travel, abnormal noise from the drive housing, or an inability to propel the drum altogether — all of which interrupt compaction passes and require immediate attention.
