company news about New Stock Release 05819031 BW138AC Roller Travel Hydraulic Motor Original Parts Tandem Roller

Release date: 22 October 2026. We have just added a fresh batch of the 05819031 travel hydraulic motor to stock. The motor is built to original parts specification and is used on the travel drive of BW138AC tandem road rollers. Repair workshops and contractors who have been waiting for this part can now order from ready stock instead of waiting for a factory lead time.

The travel hydraulic motor is the component that turns hydraulic pressure into rotary torque at the drum side of a tandem roller. When it wears out, the symptoms are easy to recognize: the machine loses travel speed, one drum creeps or stops, the motor housing runs hot, or oil starts to leak around the shaft seal. On a paving or compaction job these faults stop production immediately, because a roller that cannot travel smoothly will leave marks on the mat and fail density checks.

Ordering the wrong motor or a modified unit often creates a second problem. Adapter plates, mismatched flanges and incorrect displacement all lead to poor low speed control, extra heat and repeat failures. The 05819031 unit is matched to the BW138AC travel circuit, so the mounting flange, shaft key and port positions line up without modification.

• Housing bore and flange checked against the original drawing before assembly
• Pressure test at working pressure to confirm the shaft seal and O-ring kit hold
• Run-in test in both directions to confirm smooth rotation and correct flow response
• Shaft key and spline checked with a gauge to avoid installation delay on site
• Surface protected against rust for sea freight, with test record available on request

The 05819031 motor suits BW138AC tandem rollers working on highway construction, municipal road repair, industrial yard compaction and parking area paving. It is also a sensible shelf item for workshops that service roller fleets, because travel motor failures are one of the most common downtime causes on older tandem machines.
