Product Overview

 

CAT 2579370 is a high-performance hydraulic motor specially designed for Caterpillar BU115 and BU118 Utility Brooms. It is the core replacement component for the rotary drive of this model of brooms. This product directly replaces the original part number 2579370 and adopts the same installation dimensions, shaft extension specifications and hydraulic interfaces as the original, ensuring a perfect match with the broom assembly.

Whether it is used for road cleaning, parking lot maintenance or construction site cleaning, this motor can provide strong and stable rotational power for the brush roller, helping your cleaning equipment restore its original working efficiency. As a high-quality alternative to original parts, we offer equally reliable performance, along with higher cost-effectiveness and shorter delivery cycles.

 

Core advantages of the product

 

1. 100% size matching, plug and play
Manufactured strictly in accordance with the original CAT 2579370 drawings, the positions of the mounting flange, shaft extension, and oil port are completely consistent with the original parts. It can directly replace the damaged original motor without any modification, significantly reducing equipment downtime.
2. Optimized specifically for sweeping brush working conditions
• Low speed and high torque: The cycloidal structure provides abundant starting torque, ensuring stable operation of the brush roller during heavy-load startup (such as cleaning snow, compacting debris)
• Adjustable speed: The rotation speed of the brush roller can be flexibly controlled by adjusting the hydraulic flow to adapt to different cleaning conditions (such as dust removal in summer, snow removal in winter)
• Strong anti-pollution capability: The design has relatively loose requirements on the cleanliness of the oil, adapting to the hydraulic system conditions at the construction site
3. Sturdy and durable, suitable for harsh environments
• Heavy-duty bearings: Tapered roller bearings are used at the output end, which can withstand the radial load and impact generated during the operation of the brush roller
• Dust-proof seal: Double-lip shaft seal effectively prevents dust and gravel from entering the motor, extending the service life
• Anti-corrosion coating: The shell is sprayed with anti-corrosion paint to resist moisture and chemical corrosion
4. Reliable performance with better cost-effectiveness
Compared with original parts, this product offers a more favorable price and faster delivery time while ensuring the same performance and quality, making it an ideal choice for equipment maintenance and repair.
