Procedures Highlighted:
Component identification for ordering, visual assembly/disassembly order for parts lookup, detailed part illustrations with corresponding part numbers, cross-referencing of superseded parts, and identification of component variations based on serial number splits.
Parts Identification:
Detailed exploded views of every major system and subsystem, with each part clearly labeled and referenced to a corresponding part number in a tabulated list.
Ordering Assistance:
Essential for correctly ordering replacement parts, preventing misidentification and ensuring compatibility, especially given the serial number split.
Technical Depth:
Comprehensive for parts identification and ordering. Focuses on exploded view diagrams, component breakdowns, and part number listings. Does not typically include diagnostic procedures, repair steps, or torque specifications, which would be found in a Service Manual.
Engine Make Model:
CASE (likely sourced from a major engine manufacturer like Continental or Cummins, depending on specific build)
Engine Configuration:
Likely a 3-cylinder or 4-cylinder diesel engine. Displacement typically in the 3.0L to 4.0L range.
Engine Cooling System:
Water-cooled, with components like radiator, fan, water pump, thermostat, and hoses detailed in the manual.
Estimated Horsepower:
Horsepower ratings varied by specific engine option, generally in the 50-70 PTO horsepower range.
Fuel System Type:
Indirect injection diesel with a Bosch or Simms inline injection pump.
Standard Transmission:
Manual transmission with multiple forward and reverse gears. Often a 8-speed or 12-speed gearbox.
Optional Transmission:
Some configurations may have offered a synchronized transmission or creeper gears.
Transmission Features:
Robust gearbox design for heavy-duty agricultural work. Includes clutch, gearbox components, and final drive assemblies.
Power Takeoff Pto:
Covers PTO clutch, drive shaft, and output shaft components for the rear PTO, and potentially the live PTO mechanism if equipped.
Wheelbase:
Varies by configuration (e.g., 2WD vs. 4WD, if applicable), typically around 80-90 inches.
Tire Sizes:
Manual will illustrate wheels and hubs, essential for specifying correct tire sizes (e.g., 16.9-30 rear, 7.50-16 front, varies by option).
Operating Weight:
Typically in the range of 4,000 - 6,000 lbs (1800 - 2700 kg).
Safety Ratings:
Tractor safety standards of the era focused on ROPS (Roll-Over Protective Structure) availability, seat belts, and lighting. This manual focuses on parts, not operational safety features.
Active Safety Features:
Brake system components, steering system components. The manual details parts for these systems.
Passive Safety Features:
Operator station parts, fender components, and linkage points for potential ROPS installation. The manual covers the structural parts.
Service Intervals:
While this manual is for parts, a service manual would detail intervals for engine oil changes (e.g., 250 hours), transmission oil, hydraulic oil, and filter replacements. This parts manual is essential for obtaining those filters and fluids.
Fluid Specifications:
This manual can help identify the correct hydraulic fluid reservoirs and components where fluids are used. Specific fluid types (e.g., SAE 20W-30 engine oil, Hy-Trans or equivalent for transmission/hydraulics) would be detailed in a service manual or owner's manual. This parts manual allows you to find the correct parts for fluid service access.
Hydraulic System Capacity:
While exact capacities are not in this manual, it shows all hydraulic components (pump, filters, reservoirs, lines, cylinders) allowing for precise component replacement and service. It will list part numbers for hydraulic filters.
Common Issues Addressed By Parts:
Common wear items on tractors of this era include clutch components, hydraulic pump seals, PTO spline wear, front axle kingpins, and brake linings. This manual provides part numbers for all these critical components.
Brand Heritage:
CASE Corporation has a long history in agricultural and construction equipment, dating back to the mid-19th century, known for innovation and reliability.
Model Evolution:
The CASE 970 was part of a broader line of utility tractors that evolved over decades, building on previous designs and incorporating technological advancements of its time. The serial number split indicates evolutionary changes in components or design.
Serial Number Significance:
The 'BEFORE SN 8672001' designation is critical. It indicates that component designs, part numbers, or manufacturing processes changed at or around this serial number, making this manual specific to earlier production units.
Production Period:
The CASE 970 was produced in the 1970s and early 1980s. This manual specifically covers models manufactured before a significant component change at SN 8672001.
