Part of the Case Operator Manuals.
All 90 pages of this Case International 664 Diesel Tractor Operator Manual (OEM #1084107R1) focus on one thing: keeping your tractor running the way the factory intended. Inside: a full instrument panel walkthrough covering the torque amplifier, speedometer-tachometer, temperature gauge, and oil pressure tellite, plus step-by-step operating procedures for the three-point hitch, independent PTO, auxiliary hydraulic valves, and remote cylinders. You also get a complete lubrication guide with service intervals, a preventive maintenance schedule, cold weather precautions, tire inflation tables, and a specifications section covering engine capacities, PTO shaft speeds, and electrical system details. Set the water pump belt deflection to 7/8 inch under a 25-pound load and fill the radiator 1-1/2 inches above the core when cold. No more guessing at fluid levels or service schedules. Bookmarked by section, it opens on any device; grab your phone, walk to the machine, and get to work.

Case 664 Diesel International, 664 Diesel, International 664 Diesel Common Problems This Manual Covers
Temperature gauge climbs steadily toward the red zone during normal field operation
Shut the engine down and let it cool before removing the radiator cap. Fill the cooling system to 1-1/2 inches above the radiator core when cold (page 47). Clear debris from the radiator fins blocking airflow. Check water pump and alternator-generator belt tension on page 48: correct deflection is 7/8 inch under a 25-pound load at the midpoint between pulleys.
Manual Section: Cooling System p. 47Brake pedals feel soft, uneven, or require more foot travel than normal to stop
Check brake pedal free movement on page 5: each pedal must have exactly 1-3/4 inches of free travel before the brake engages. Adjust the linkage to equalize pressure side to side if one pedal bites sooner than the other. Test by pressing both pedals together on level ground and confirming equal stopping force before operating on slopes or public roads.
Manual Section: Supplement to Operators's Manual (1084107R1) International 664 Tractor p. 5Frequently Asked Questions
How to read serial number on International Harvester 664 tractor
The manual instructs owners to specify the tractor and engine serial numbers, including prefix and suffix letters, when ordering parts. Illustrations on page 3 indicate the general locations for both the diesel engine serial number and the tractor serial number on the machine. p. 3
How do you fix case International 664 tractor won't start or cranks over slowly in cold weather?
Verify coolant is 1-1/2 inches above the radiator core before cold-weather operation (page 47). Check battery terminals for corrosion and clean if needed. Follow the ether starting aid procedure on page 22 for below-freezing conditions. If the engine still won't crank after cleaning terminals, charge or replace the battery before attempting another start. p. 22
How do you fix oil pressure or alternator tellite stays on after engine reaches normal operating speed?
Stop the engine immediately if either tellite stays lit at running speed. Test the tellite bulbs and check engine oil level first, as described on page 53. Then verify the alternator-generator belt deflects 7/8 inch under a 25-pound load at the midpoint between pulleys (page 48). A slack belt prevents proper charging and will keep the alternator tellite lit. p. 53
How do you fix engine misfires or runs rough and loses pulling power in the field?
Replace both the primary and final fuel filters as covered on page 25. After fitting new filters, bleed trapped air from the fuel lines following the venting procedure on page 19. While stopped, check alternator belt deflection: correct tension is 7/8 inch under a 25-pound load midway between pulleys (page 48). Restart and confirm smooth running under load. p. 25
