This 128-page Case/international Shop Manual PDF covers the complete factory service scope for the 235, 235H, 245, 255, 265, and 275 tractors, spanning front axle systems (both two-wheel-drive and all four-wheel-drive variants) through engine rebuild, transmissions, and hydraulic lift overhaul. Inside: full electrical wiring diagrams, hydraulic schematics with pump, auxiliary valve, and lift cover procedures, and a condensed service data section packed with tune-up specs, clearances, and fluid capacities. Four distinct transmission types cover this family (sliding gear, constant mesh, synchromesh for the 245/255/265, and the 235H hydrostatic unit), each with complete teardown and troubleshooting procedures. Set your 275 clutch release lever to 20.3-21.7 mm before closing up the clutch pack, and confirm alternator output at 14 volts, 8 amps at 1300 rpm. Your dealer can't quote factory spec for a tractor this old. One download, bookmarked by system, searchable by keyword.

Case/international 235-275 Common Problems This Manual Covers
Case/International 235 hydraulic hitch will not raise despite engine running at operating speed p. 117
Check the drop rate control knob on the lift cover first; it must be open, not fully closed. Verify hydraulic fluid level meets capacity specs on page 5. If the hitch still will not lift, connect a flow meter as described on page 117 to test pump output and confirm relief pressure is within specification.
Manual Section: Hydraulic Lift SystemStarter clicks but engine won't crank, no response to key in any position p. 57
Test each safety switch with a voltmeter or continuity tester, checking that stroke measures 4-5 mm (0.16-0.20 in.) per specs on page 58. If switches pass, pull the starter and measure pinion gap clearance: it should be 0.5-2.0 mm (0.0197-0.0787 in.) when the solenoid is engaged (page 57). Replace any switch or solenoid that falls out of spec.
Manual Section: Electrical System Safety SwitchesHydrostatic transmission won't move in either direction or operates erratically at any speed p. 99
Verify fluid quantity and quality first per page 99; the hydrostatic unit is sensitive to low or dirty fluid. Measure forward drive pressure, reverse drive pressure, and charge pressure at the test ports (specs on page 99). If charge pressure falls below specification, suspect the charge pump or a clogged filter before splitting the transmission.
Manual Section: Transmission (235H Hydrostatic)Clutch slips under load with delayed engagement and pedal sinking toward floor p. 68
Remove the clutch and inspect disc lining thickness; replace if below the 0.3 mm (0.012 in.) wear limit (page 68). Verify rivet countersink depth falls between 1.2-2.0 mm (0.05-0.08 in.), since shallow rivets score the flywheel face. Check release lever height and adjust to spec before reinstalling.
Manual Section: ClutchEngine misfires and bogs under load with excessive black exhaust smoke and rough idle p. 55
Replace fuel filters at least once yearly or whenever dirty (page 55). If misfiring continues, use the injector line disconnection test in the Diesel Fuel System section: with the engine running, loosen each injector line fitting one at a time and note which cylinder, when cut, causes no rpm change. Send those nozzles for bench testing.
Manual Section: Diesel Fuel SystemAlternator not charging, battery drains between uses, charge warning light stays illuminated p. 57
Check fan belt deflection: should be 13 mm (1/2 in.) at
Frequently Asked Questions
What are the torque specs for rear wheel to axle hub bolts on Case/International 235 and 235H models?
The rear wheel to axle hub bolts for Case/International 235 and 235H models should be tightened to 118-132 N.m (87-98 ft.-lbs.) torque. This specification is crucial for proper assembly and safe operation.
What is the torque specification for rear axle stud nuts on Case/International 245, 255, and 275 models?
For Case/International 245, 255, and 275 models, the nuts securing the rear wheel rim to the wheel disc should be tightened to 152-172 N.m (112-127 ft.-lbs.) torque. The rear wheel to axle hub bolts should be tightened to 118-132 N.m (87-98 ft.-lbs.) torque.
What are the replacement specifications for Starter solenoid?
The manual does not provide specific replacement specifications for the starter solenoid itself, such as a part number or electrical ratings. However, it does describe the disassembly process and an adjustment specification for the pinion gap when the solenoid (13) is engaged: the pinion (3) should move to within 0.5-2.0 mm (0.0197-0.0787 in.) of the end of the pinion shaft (6).
What are the replacement specifications for Fuel filters?
The manual specifies that a renewable paper filter element type fuel filter (4) should be installed. It should be replaced at least once each year or whenever it appears dirty, or if the engine is misfiring or has lost power.
