Case 410, 420, 420CT Common Problems This Manual Covers
Case 420 engine fails to start when cold below 40 degrees even with glow plugs engaged p. 181
Remove the starter motor and inspect the brush length as detailed on page 181. Replace the brush holder assembly if the brush fastened to it measures less than 11 mm (7/16 inch). Verify armature runout does not exceed 0.05 mm (0.002 inch) on page 182.
Manual Section: Starter and Starter Solenoid Test ProceduresParking brake engages and does not unlock or release when commanded by the operator p. 335
Test the brake system release pressure. For 410 machines, verify the maximum pressure when fully disengaged reaches 1100 to 1500 kPa (160 to 217 psi) as shown on page 335. If pressure falls short, inspect the solenoid and apply 11 120 N (2500 pound-force) friction stack compression force on page 354.
Manual Section: BrakesEngine will not turn over because the auxiliary hydraulics foot pedal is stuck out of neutral p. 479
Inspect the auxiliary spool in the control valve and confirm it rests in the neutral position. Adjust the control cable until the auxiliary hydraulic pedal sits completely horizontal as described on page 479. Start the machine and verify low idle engine speed stays at 1050 ± 50 r/min.
Manual Section: Mounted EquipmentReduced loader lifting capacity and slow boom movement during heavy material handling p. 363
Check the loader control valve main relief pressure on page 363. Connect your test gauge and verify the system maintains 20 700 ± 345 kPa. If pressure drops below specification, inspect the gear pump flow and verify total hydraulic system capacity holds exactly 50.2 liters.
