Need help?Do you have a question about the Case CX470B and is the answer not in the manual?
The CX470B Crawler Excavator is a heavy-duty construction machine designed for various earthmoving and excavation tasks. This service manual provides comprehensive information for its maintenance, repair, and operation, ensuring optimal performance and longevity.
The CX470B is a powerful crawler excavator, primarily used for digging, lifting, and loading materials in construction, mining, and demolition environments. Its robust design and hydraulic system enable it to handle demanding tasks with efficiency. The machine features a main boom, arm, and bucket, which are hydraulically operated to perform excavation and material handling. It is equipped with a swing motor and reduction gear for rotating the upper structure, and drive motors with final drive transmissions for track movement. The undercarriage, consisting of tracks, rollers, and a take-up roller, provides stability and mobility across various terrains. The operator's cab is designed for safety and comfort, with controls for all machine functions and an optional FOPS (Falling Object Protective Structure) for enhanced protection.
The manual details various technical specifications crucial for understanding the machine's capabilities and for proper servicing.
Type, Serial Number, and Year of Manufacture: These identifiers are essential for part orders and technical assistance, ensuring the correct components and information are provided. Engine: The engine's make and type, along with its serial number, are specified. The manual emphasizes the use of genuine Case engine oil, recommending "No. 1 ENGINE OIL" (MS 1121, SAE 15W-40) or oils meeting ACEA E7 / API CI-4 categories. Oil viscosity ranges are provided for different ambient temperatures, including mineral, semi-synthetic, and synthetic base oils. Fuel System: The machine requires specific diesel fuel to meet emission control regulations (3rd-stage) and ensure optimal engine performance. Fuel specifications include:
The CX470B is designed for versatility and operational safety. Control System: The machine features a sophisticated electrical system with service connectors, engine and main body error codes (DTCs), and troubleshooting guides for the 6UZ1 engine. Electrical circuit diagrams are provided for diagnostics. Operator Safety: The manual emphasizes strict adherence to safety warnings and cautions. Operators are instructed to read the operator's manual, understand control functions, and be aware of their surroundings. Personal protective equipment (hard hat, safety shoes, ear protection, eye protection, heavy gloves, reflector clothing) is recommended. The machine is designed for a single operator, with no riders allowed. Hydraulic Operation: Procedures for checking and testing hydraulics, as well as cycling cylinders to remove air, must be followed carefully, ensuring all personnel are clear of the working area. Engine Exhaust: Warnings against engine exhaust fumes in enclosed spaces are provided, recommending exhaust pipe extensions and proper ventilation. Heavy Components: The manual highlights that some machine components are very heavy, requiring suitable lifting equipment and additional help during servicing. Hydraulic Oil Pressure: A warning about pin-sized streams of hydraulic oil under pressure penetrating the skin is included, advising immediate medical treatment if exposure occurs and recommending the use of cardboard or wood to check for leaks.
The service manual provides extensive guidelines for maintaining the CX470B to ensure its reliability and extend its service life. Cleaning: All metal parts, except bearings, should be cleaned with a suitable solvent or by steam cleaning (avoiding caustic soda). Bearings require cleaning in a suitable solvent and air drying (never compressed air). Oil passages should be cleaned with compressed air. Inspection: Regular inspection of all disassembled parts for wear and damage is crucial. Worn or damaged parts must be replaced with genuine Case service parts. Small scoring or grooves can be removed with a hone or crocus cloth. Bearings: Bearings should be checked for smooth action and replaced if loose or rough. Needle bearings require careful installation, with petroleum jelly applied to their inner and outer diameters. Gears: All gears must be inspected for wear and damage, and replaced as necessary. Seals and Gaskets: New oil seals, O-rings, and gaskets should always be installed, with petroleum jelly applied to aid installation. Shafts: Shafts must be checked for wear, damage, and condition of bearing and oil seal surfaces. Lubrication: Only specified oils and lubricants from the Operator's or Service Manuals should be used. Failures due to non-specified lubricants are not covered by warranty. Bolt and Nut Tightening: Bolts and nuts should be tightened alternatingly (left/right, top/bottom) for uniform force. Critical locations may require engine oil on threads and additional securing methods (wire, cotter pins). Retightening is required after the first 50 hours for new machines and every 250 hours thereafter.
