Caterpillar M313D2/M315D2/M317D2 Wheel Excavator Original Factory Compatible Hydraulic Main Pump Assembly

Special for dedicated use, precisely matched without error
Tailored specifically for the Caterpillar D2 series wheel excavators. Different from the general crawler excavator hydraulic pumps, it features exclusive flange dimensions, regulator parameters, and installation points that perfectly match the M313D2, M315D2, and M317D2 models. No need for modification or debugging, it can be directly installed and replaced. This avoids issues such as deviation in universal part compatibility, inability to properly link the hydraulic system, and installation misalignment. It has excellent compatibility, significantly reducing equipment modification costs and installation time.

Powerful and with stable high-efficiency operation
It adopts a high-end piston-type hydraulic structure and is equipped with the original factory power adjustment component. The oil pressure output is uniform and stable, with extremely low power transmission loss. It can perfectly adapt to complex working conditions such as heavy-load excavation, continuous operation, and high-low speed switching of the equipment. It effectively restores the original factory power performance of the equipment, eliminating problems such as power attenuation, slow operation, and insufficient pressure during operation. It continuously ensures high-intensity and high-efficiency construction of construction machinery and significantly improves the progress of site operations.

Highly durable and resistant to damage and wear, with a longer service life.
The pump body is made of thickened high-strength alloy material. The core piston, bearings, and seals all use high-quality matching components. They have undergone precise processing and anti-pressure and wear treatment, possessing extremely strong pressure resistance, high-temperature resistance, and wear resistance. It can adapt to harsh working environments such as dust on construction sites, high and low temperatures, and heavy load impacts. It is less likely to experience oil leakage, pressure relief, pump body wear, or component damage. Compared to ordinary refurbished parts, its service life is significantly improved, reducing the hassle of frequent maintenance and replacement.

High cost-effectiveness, cost reduction and quality improvement with strong compatibility
This product is produced in accordance with the original factory's quality standards. Its performance, parameters and usage effect are infinitely close to those of the original factory parts, and it can completely replace the expensive original factory parts. At the same time, it avoids the compatibility limitations and aging defects of the old model parts 252-5002 and 251-8028. The upgraded model has more stable performance and lower failure rate. With an affordable price, it achieves the quality of the original factory level, significantly reduces the costs of equipment maintenance, repair and refurbishment, and its cost performance far exceeds that of ordinary refurbished pumps and general pumps of the same type.
