Hydraulic Pump Specification
Model Number: 172-932210R-6684
Type: Hydraulic pump (likely an axial piston or gear pump, though specific type isn’t stated).
Application: Designed for use in heavy-duty mobile hydraulic systems, specifically in articulated dump trucks.
------
Compatibility
Manufacturer: Caterpillar Inc. (abbreviated asCAT).
Applicable Equipment:
• Model 583970: Likely a specific part or system identifier within Caterpillar’s catalog (could be a chassis, engine, or hydraulic assembly code).
• Articulated Dump Trucks:
• 725 Model: A medium-sized articulated dump truck in Caterpillar’s lineup, typically used in construction, mining, or quarrying.
• 730 Model: A larger variant of the 725, offering higher payload capacity and power for heavy-duty applications.
Key Feature: The pump is compatible with both the725and730 models, which share similar hydraulic system architectures despite differences in size/capacity.

Technical Context
1. Articulated Dump Trucks:
• These vehicles have a pivoting joint ("articulation") between the cab and dump body, allowing tighter turning radii and better maneuverability on rough terrain.
• Hydraulic systems in such trucks control steering, dump bed lift, and sometimes braking or suspension.
2. Hydraulic Pump Role:
• The pump converts mechanical power (from the engine) into hydraulic flow/pressure to operate actuators (e.g., cylinders for lifting the dump bed).
• Must withstand high pressures, vibrations, and harsh environmental conditions (dust, temperature extremes).

Additional Notes
• Part Number Clarity: The model number (172-932210R-6684) is likely a Caterpillar OEM part number, used for ordering or identifying replacements.
• Cross-Reference: If sourcing this pump, verify compatibility with specific truck serial numbers or hydraulic system revisions, as Caterpillar may update designs over time.
• Alternatives: Aftermarket or remanufactured pumps may use different numbering systems but claim equivalency—always check technical specs.
