Engine Make:
Case IH (Often utilizes Sonalika or other licensed engines, check specific model variant)
Engine Model Typical:
Likely a 4-cylinder diesel engine. Specific model code (e.g., 4CT, 4.2L) not provided but common for this tractor class.
Displacement Cc:
Typically around 4100-4200 cc for this class (approx. 4.2 Liters)
Horsepower Net Peak:
Approx. 70 HP (as per model designation). Specific rating may vary by market.
Torque Peak Nm:
Torque figures would be specified in the manual; typically in the range of 250-300 Nm for this horsepower class.
Fuel Injection Type:
Direct Injection, typically mechanical or common rail depending on the specific build date and emissions standards.
Transmission Type Standard:
Manual Synchromesh Transmission (MST) with partial power shift or creeper gears common.
Transmission Type Optional:
Powershuttle or hydrostatic transmission options may have been available depending on region and configuration.
Pto Speeds:
Standard PTO speeds (e.g., 540/1000 RPM) and their engagement procedures.
Gear Range:
Typically offers multiple forward and reverse gear ranges (e.g., 8F x 8R or 16F x 16R with creeper).
Engine Oil Change:
Typically every 250 hours or annually. Manual will provide exact interval and oil specification.
Hydraulic Fluid Change:
Typically every 1000-1200 hours or every two years. Manual will specify.
Fuel Filter Replacement:
Intervals vary, often every 250-500 hours or as needed based on fuel quality. Manual will detail.
Air Filter Maintenance:
Service based on operating conditions, often checked daily and replaced as needed. Manual will provide guidance.
Engine Oil Type:
Typically SAE 15W-40 API CI-4 or CJ-4 diesel engine oil. Manual will confirm exact specification and API rating.
Hydraulic Fluid Type:
Typically UTTO (Universal Tractor Transmission Oil) or a specific Case IH-approved fluid. Manual will specify grade and capacity.
Coolant Type:
Ethylene glycol based coolant with a suitable anti-corrosion package. Manual will provide type and mix ratio.
Common Wear Points:
Operator neglect of routine maintenance, wear on clutch components, hydraulic system leaks, and electrical connection corrosion can be common on older tractors. Manual helps prevent and diagnose these.
Engine Reliability:
Generally reliable engines, but like all diesels, require proper fuel and oil maintenance. The manual is crucial for any engine-related troubleshooting.
