J. I. Case 200–600 Common Problems This Manual Covers
Case 300 power steering hoses leaking fluid, pump housing wet and steering effort increasing
Check the troubleshooting chart to confirm the symptom: loss of assistance, unequal turning radius, or fluid foaming at the reservoir. Remove the pump and cylinder hoses, inspect for cracking or soft spots, and replace any hose showing seepage. Flush the reservoir and inlet screen before refilling to keep contamination out of the relief valve.
Manual Section: Power Steering System Troubleshooting ChartThrow-out yoke and clutch rod worn or loose, clutch pedal has excessive free play
Inspect the throw-out yoke and clutch rod for wear at the pivot points and linkage pins. Turn the housing slightly to center the release yoke, then tighten the housing retaining screws to 25-30 ft.-lbs. (200B, 300, 300B, 350, 500B). Replace the clutch rod if pin holes are elongated, and recheck pedal free play after adjustment.
Manual Section: Engine Clutch p. 46Hydraulic pump making noise with low output pressure, oil foaming visible in the reservoir
Check the hydraulic pump noise troubleshooting section on page 75. Drain and inspect the reservoir for foaming, which points to a fractured intake tube or oil overheated above 190°F from too much oil in the reservoir. Verify gear backlash is not misaligned, check pump O-rings for wear, and correct the fluid level before restarting the pump.
Manual Section: Hydraulic Pump Noisy or Low Output Troubleshooting p. 75Front and rear wheel hub seals packed with twine, fluid leaking from both hubs
Remove the hub covers front and rear and clear out any wrapped twine or debris fouling the seal lip before it cuts into the rubber. Replace both hub seals as a set rather than one side, and clean the axle housing thoroughly so fresh debris cannot re-enter. Refill with the specified axle lubricant and check for leakage after the first hour of operation.
Manual Section: Final DriveTractor loses power or stalls in certain gears, uneven power shift performance under load
Check linkage adjustment on the control valve and clutch pressure regulator for binding or excessive play that would cause stalling in specific gear ranges. Inspect the convertor fluid level along with the breather and filter for contamination, since low or dirty fluid causes power shift hesitation under load. Adjust linkage per the Case-O-Matic operation section and retest through each gear range before returning to service.
Manual Section: Case-O-MaticFrequently Asked Questions
What are the torque specs for the main bearing bolts on a J.I. Case 400B?
For J.I. Case 400B non-diesel models, the main bearing bolts should be tightened to a torque of 90-100 ft.-lbs. This specification is crucial for proper engine assembly, as detailed in paragraph 33. p. 23
What is the cylinder head tightening torque for J.I. Case 350 non-diesel models?
For J.I. Case 350 non-diesel models, the cylinder head retaining stud nuts should be tightened to a torque of 95-100 ft.-lbs. The tightening sequence shown in Fig. C759 must be followed for correct assembly. p. 16
What is the valve tappet gap adjustment for J.I. Case 300B diesel engines?
For J.I. Case 300B diesel engines, the valve tappet gap should be adjusted to 0.014 hot. This adjustment is performed after the engine has warmed to operating temperature. p. 16
What is the crankcase oil capacity with filter for J.I. Case 300 Diesel models?
The crankcase oil capacity with filter for J.I. Case 300 Diesel models is 6.0 quarts. For non-diesel models, the capacity is 5.0 quarts, as listed in the service data. p. 4
