Case Farmall 460, 560, International 560 Operators Manual (incl. Wiring)

Remove the rear axle housing inspection cover and check for metal particles in the lubricant — this is a known early-production issue. Drain the rear axle housing completely and inspect gears for spalling or pitting. Torque rear wheel hub clamp bolts to 390-460 foot-pounds per page 16 before reinstalling. If metal contamination is present, the drive assembly requires replacement; do not return to service with contaminated oil.

Check the wiring diagram on page 50 and trace ignition circuit from the switch to the distributor. Inspect all connections for corrosion or moisture intrusion, especially at the break-away connector socket. Verify the ignition switch position at page 14. Clean and reseat all terminals; if repeated fuse burnout occurs, inspect the lighting circuit wiring per page 43 for a short before condemning the ignition system.

Check whether the transport lock knob was accidentally turned fully in while adjusting seat spring tension — this is the most common cause of sudden hitch failure. Refer to page 25 for the Hydra-Touch control handle layout and verify the transport lock is released. Also confirm fluid level in the transmission and differential case; Hydra-Touch operation depends on shared fluid, and the system holds approximately 10 gallons on the Farmall 460 or approximately 16 gallons on the Farmall 560 and International 560 (page 55).

Inspect all hydraulic self-sealing couplings at the bottom of the tractor — a partially unseated coupler restricts flow and is often invisible without hands-on pressure. Press each coupling fully until it clicks locked, per page 25. Check the fluid filter condition described in the Hydra-Touch section; a clogged filter starves the pump. Also clean the oil pump screen per page 54 if sluggish operation persists after coupling inspection.

Stop the engine immediately and investigate before restarting. Check the oil level with the gauge rod on the engine; capacity is 9 quarts. Remove and clean the oil intake screen per the procedure on page 54 — a plugged screen is a common cause of pressure drop. Verify oil viscosity matches operating temperature using the specifications on page 54. If pressure does not recover after refill and screen cleaning, inspect the oil pump and main bearings.

Check the charge indicator per page 14; a continuous discharge reading means the generator is not keeping up or the regulator has failed. Inspect the fan belt for correct tension and wear at page 47 — a slipping belt is the leading cause of undercharging. Clean the generator and regulator terminals described on page 48. If belt tension and connections are correct but discharge continues, test the generator output and replace the regulator.
