| 2. Precision Fit | 100% matched to D155A-3/5 housing | Universal fit that may cause oil leakage |
| 3. Pressure Rating | Tested to withstand 25MPa+ peak pressure | Often fails under high-load stress |
| 4. Service Life | Estimated 8,000+ operational hours | Unpredictable, often less than 3,000 hours |

If your D155A bulldozer is experiencing slow hydraulic response, unusual whining noises from the pump area, or increased oil temperature, the gear pump internal seals or gears may be worn. Replacing it with a 705-56-34630 OEM replacement prevents further damage to the transmission system.
First, check the hydraulic filters for metal shavings. If contamination is found, the 705-56-34630 pump may have suffered internal cavitation. We recommend a complete system flush before installing the new pump to ensure longevity.
Our units feature an OEM-standard tri-metal structure and are trusted by repair shops and equipment fleets worldwide for their consistent performance in extreme environments.
