All 222 pages of this International 384, 238 Service Manual (OEM #SM-51A) are aimed at one job: putting your tractor back to factory condition, component by component. If you're tracking down the International 384, 238 service manual pdf, this is the OEM document, not an aftermarket reprint. Inside you get hydraulic schematics tracing every circuit from pump to rockshaft, wiring diagrams covering the alternator, keyswitch, fuse boxes, and lighting circuits, plus a full standard torque section with bolt data spanning the entire drivetrain. Set front axle toe-in between 0 and 1.59 mm (0.062 in) before you button up the steering — that kind of factory number is what separates this manual from forum guesses. Your machine is down. Pull up this bookmarked PDF on any device, jump straight to the section you need, and get the right spec on the first try.

International 384, 238 Common Problems This Manual Covers
International 384 stored for years, cranks but won't fire; metering valve suspected clogged p. 47
Drain the fuel tank completely and remove the injection pump for bench inspection per page 47. Soak the metering valve in carb cleaner for at least 30 minutes to break down varnish deposits from stale diesel. Blow all fuel galleries dry with compressed air. Verify injection pump timing marks are aligned before cranking.
Manual Section: Fuel SystemSteering wanders or pulls to one side unpredictably, front wheels shimmy at low speed p. 115
Measure front axle toe-in first; the specification is 0 to 1.59 mm (0.062 in) per page 14. If toe is correct, remove the steering box cover per page 115 and inspect the worm wheel and shaft for flat spots or pitting on the contact faces. Check the drag link and drop arm ball joints for vertical and lateral free play.
Manual Section: Front Axle & SteeringDual clutch slips under drawbar load or drags, pedal won't disengage cleanly p. 61
Remove hood and grille to reach the clutch housing per page 61. Clean both driven disc faces with brake cleaner; handle only by the hub. Inspect pressure plate springs for fatigue cracks. Measure friction disc thickness and compare against Technical Specifications on page 10. Adjust pedal free travel before reinstalling.
Manual Section: Engine ClutchHydraulic lift climbs slowly or creeps down with implement attached under load p. 141
Check hydraulic fluid level before removing anything. Inspect pump gears and housing per page 141 for scoring or wear. Trace the pressure circuit using the hydraulic schematic on page 12 to isolate whether the fault is at the pump, relief valve, or control valve assembly. Verify the rockshaft and draft control linkage move freely.
Manual Section: Hydraulic SystemBrakes grab unevenly or tractor pulls hard to one side when stopping p. 105
Inspect both disc brake assemblies together per page 105; unequal braking almost always means oil contamination or a glazed pad on one side. Check the cross shaft bushings for seizure. Adjust the compensating linkage so both pedals lock together evenly. Torque all fasteners to specification values on page 9 after reassembly.
Manual Section: BrakesFrequently Asked Questions
How to read the serial number on International 384?
The engine serial number is stamped on the right side of the crankcase. The tractor serial number is stamped on a nameplate attached to the right side of the clutch housing.
How to reset the PTO on International 384?
While there is no explicit 'reset' procedure for the PTO, the manual provides adjustment procedures. For the PTO lever, adjustments include setting the lever height and setscrew clearance. For the PTO Countershaft and Driving Shaft, it is important to check the clutch disengaged position.
How to reset fuel system International 384
There is no explicit 'reset' procedure for the entire fuel system. However, adjustments for the governor lever and foot accelerator are provided. This includes adjusting the governor control rod to achieve 'low idle' and 'high idle' positions, and checking the foot pedal stop.
What are the replacement specifications for Steering worm wheel and shaft assembly?
While specific replacement dimensions for a new steering worm wheel and shaft assembly are not provided, the manual details critical adjustment specifications after assembly or replacement. The steering shaft end float should not exceed 0.08 mm (0.003 in), and the thrust screw should be adjusted to a torque of 70 to 80 kgm (50 to 60 lbf) to ensure proper operation.
