Engine Oil Type Recommendation:
Typically API CD or CE rated diesel engine oil, SAE 30 or 10W-30 depending on ambient temperature. Refer to specific engine data in manual for precise API service category.
Hydraulic Fluid Type:
Case IH Hy-Tran Plus or equivalent UTFMS (Universal Tractor Transmission Oil). Specific viscosity grades may apply.
Transmission Fluid Type:
Likely UTFMS (Universal Tractor Transmission Oil) or gear oil, depending on the specific transmission design (e.g., independent PTO vs. combined sump). Manual is crucial for precise spec.
Coolant Type:
Ethylene glycol based antifreeze mixed with distilled water (typically 50/50 ratio). Specific type (e.g., conventional green) should be confirmed from manual.

Worn clutch plates, hydraulic pump wear, injector pump issues (diesel), carburetor adjustment problems (gasoline), PTO seal leaks, and differential bearing wear.
Tune Up Components:
Spark plugs, ignition points, condenser, fuel filters, air filter, oil filter, and potentially distributor cap/rotor.
Brand History Context:
Case tractors have a long history of agricultural innovation, with the '600' series representing a robust line of utility and row-crop tractors from the mid-to-late 20th century.
Model History Context:
The 630 and 640 models were successors to earlier Case designs, offering improved power, hydraulics, and operator comfort for their era. They served as versatile workhorses on farms.
Production Period Estimate:
Likely produced during the 1960s and early 1970s.
