Case 1840 SKID STEER, 1845C Uni-Loader Common Problems This Manual Covers
Case 1840 right side drive does not engage or stalls under load during operation p. 392
Pressure test the hydrostatic charge circuit at full throttle; minimum charge pressure must read 26 to 28 bar (390 to 415 psi) on page 392. If the reading is low, inspect the piston pump for internal wear and recheck the neutral adjustment before replacing the pump assembly.
Manual Section: Hydrostatic Drive System TroubleshootingBackup alarm fails to sound when both control levers are moved rearward toward the operator p. 267
Jump the front piston pump backup alarm switch circuit and start the engine. Move both control levers to the rear; the alarm must sound. If silent, check wire 2 and ground wire 3 between switches, then replace the rear piston pump backup alarm switch per page 267 and check the 10 ampere fuse on page 258.
Manual Section: Electrical System TestingAir filter restriction indicator does not light despite a visibly clogged or dirty filter element
Disconnect the air filter restriction switch connector and test continuity with the engine off; the switch should close as vacuum builds past its rated restriction point. Check the wiring back to the instrument cluster for an open circuit or corroded connector, and verify the cluster bulb itself before condemning the switch.
Manual Section: Electrical System TestingHydraulic filter warning light illuminates on the dash while the engine is running at full throttle p. 268
Run the engine at full throttle and watch the warning lamp per page 540; if it stays lit, replace the hydraulic filter. The restriction switch is normally open and closes at 3 ±0.3 bar differential (40 ±4 psi) per page 268; replace the switch if it falls outside that range. Hand tighten the new filter 1/2 turn past O-ring contact.
Manual Section: Hydraulic System Troubleshooting ProcedureSteering or loader control levers feel loose, sloppy, or fail to return to neutral position p. 751
Check clearance of the steering control levers in the front panel; initial adjustment minimum is 38 to 42 mm (1.50 to 1.65 inches) per page 751. Inspect the centering mechanism for worn pins or bushings and adjust until the lever returns squarely to center, confirming loader lever travel matches the 25 degree angle on page 760.
