Hardened bevel & 3-stage planetary gears, strong resistance to compaction impact

Multi-layer fluorine rubber floating seals for zero leakage under high temperature

Standard G3/4 oil port, easy lubrication maintenance with ISO VG220 gear oil

Affordable durable aftermarket replacement versus expensive genuine OEM assemblies

Q: Which machines fit this gearbox reducer?
A: Gearbox Part No.59390872 (interchangeable 59186387) is exclusively designed for Ingersoll Rand DD110, DD110HF and DD130 double-drum asphalt compactors.

Q: Direct OEM interchangeable?
A: Yes. Input spline flange, output wheel mounting flange, bolt hole layout and overall dimensions match the original OEM unit 1:1, plug-and-play replacement without cutting or adapter modification.

Q: Key technical specs?
A: Rated working pressure 35 MPa, peak pressure 42 MPa; max output torque range 92000–110000 N·m. It adopts integrated spiral bevel + 3-stage carburized hard-tooth planetary transmission structure.

Q: Compatible with original hydraulic motors?
A: Perfectly matched with original Rexroth A6VM107 / A6VE107 hydraulic motors via standard 14-tooth internal spline input flange, fits factory original walking hydraulic circuits directly.

Q: Stable compaction performance?
A: Precisely ground carburized alloy bevel and planetary gears minimize vibration, friction and abrasion, delivering consistent low-speed high torque to handle long-hour asphalt paving, climbing and frequent start-stop construction work.

Q: Heavy-duty upgraded options available?
A: Optional thickened reinforced gear assemblies, multi-layer fluorine rubber floating seal kits and heavy-duty roller bearings for frequent overload, high-temperature asphalt construction sites.

Q: Recommended lubricant & maintenance cycle?
A: ISO VG220 EP extreme pressure industrial gear oil. Check oil level and seals daily; fully drain and replace gear oil every 1000 working hours under dusty road construction conditions.

Q: Troubleshoot leakage & overheating?
A: Retighten mounting bolts for minor oil seepage; replace full seal kit for serious leakage. Overheating generally results in degraded lubricant, insufficient oil volume or worn internal gears. Follow official maintenance guides, unauthorized disassembly is not recommended.

Q: Warranty terms?
A: 12-month factory warranty. Free technical consultation and free spare parts replacement for failures caused by non-human damage under standard operating conditions.
