RM43908326 Volvo Roller Drum Drive Gearbox Hydraulic Motor | Heavy-Duty & Perfect Match

RM43908326 aftermarket hydraulic drum drive motor with integrated planetary gearbox serves as a direct replacement component exclusively built for Volvo SD series single-drum soil compactors. This heavy-duty hydraulic assembly centers on low-speed high-torque performance to satisfy harsh road compaction construction conditions. Manufactured under strict OEM matching standards, it delivers seamless mounting and flawless fitting for Volvo SD115, SD115B, SD135B, SD115D, SD115F, SD116DX, SD116F, SD122 and SD135 compactors. The integrated unit combines a piston hydraulic motor and multi-stage planetary reduction gearbox in one compact housing. The hydraulic motor delivers steady rotational power, while the built-in gearbox amplifies output torque to drive the roller drum. The integrated structure minimizes power transmission loss, allowing the compactor to maintain stable travel performance under heavy load, and extends overall service life of the walking system.

The accessories, from design to material, are all optimized around energy-saving goals. The internal flow channel of 11707967 pump has been designed through fluid mechanics simulation, reducing the reflux loss of hydraulic oil by 22%. When outputting the same power, its energy consumption is 15% lower than that of ordinary pumps. The 11707967 motor is equipped with a variable frequency speed regulation module. It only starts high-speed heat dissipation when the equipment temperature reaches the threshold, reducing no-load energy consumption by 30% and saving over 800 kilowatt-hours of electricity annually. The seals of 11707967 parts are made of materials with low friction coefficients, reducing the frictional resistance between components and indirectly lowering the Energy consumption during equipment operation, achieving "energy-saving" in multiple aspects.

Motor and gearbox are manufactured as a single integrated assembly, no separate assembly steps required during maintenance. It fully replicates the original OEM installation dimensions of Volvo SD series rollers, enabling plug-and-play replacement without extra modification to machine structures, greatly shortening equipment downtime for repair.

• RM43908326 Hydraulic Piston Motor: As the core power execution unit of the roller walking system, it converts hydraulic pressure energy into stable rotary mechanical power with optimized internal plunger flow channels to cut down hydraulic pressure loss. It delivers steady oil-driven rotation output and matches the hydraulic output parameters of Volvo SD series compactors perfectly. When the machine is traveling on heavy compacting working conditions, it automatically boosts torque output to handle heavy load pressure; during flat ground low-load traveling, it keeps smooth low-speed rotation to lower unnecessary power loss, cooperating closely with the built-in planetary gearbox to realize flexible forward and backward travel control of the steel drum.
• RM43908326 Integrated Planetary Gear Reduction Assembly: Equipped with multi-stage hardened alloy planetary gear sets, it serves as the torque amplification core of the whole drive unit. It converts the high-speed low-torque rotation from the hydraulic motor into low-speed high-torque power suitable for steel drum driving. The gear meshing clearance is precisely controlled to avoid abnormal shaking and loud noise during operation. Its integrated structure shares the same sealed housing with the hydraulic motor, forming a unified power transmission closed loop that efficiently transfers torque to the roller drum and prevents power loss caused by separate component assembly gaps.
• Built-in Sealing & Wear-resistant Auxiliary Components: This integrated drive unit comes with matched high-pressure oil seals, wear-resistant bearing sleeves and positioning flanges. The composite high-pressure oil seals block hydraulic oil leakage under long-term continuous high-pressure working conditions, adapting to dusty, muddy construction sites. Precision positioning flanges fully replicate the original OEM mounting dimensions of Volvo SD series rollers, guaranteeing high concentricity during installation to reduce friction loss during rotation. All matching auxiliary parts are tailored for this integrated drive motor, laying a solid foundation for the whole assembly's long service life and stable heavy-duty performance
