Case IH DX48, DX55 Common Problems This Manual Covers
Case IH DX48/DX55 engine won't start or cranks very slowly in cold weather
Check battery terminals for corrosion and verify the battery holds a full charge before cranking. Inspect fuel lines for wax buildup in freezing temperatures. If cranking speed is still low, top up the crankcase to full; capacity with filter is 7.0 liters. Follow the engine no-start diagnosis chart.
Manual Section: Engine Troubleshooting - GeneralHydraulic lift arms fail to raise implement or move very slowly under load p. 657
Check the transmission and hydraulic fluid level; total system capacity is 42.0 liters (11.1 U.S. gal.). Replace the hydraulic filter if past the 50-hour initial change interval. Verify the control valve moves fully through its range and the relief valve is not stuck open. Work through the lift troubleshooting steps in the Hydraulic System section at page 657.
Manual Section: Hydraulic System TroubleshootingEngine overheats, temperature gauge climbs into red zone even at normal load
Inspect the radiator core and clean debris from the fins with compressed air. Check coolant level; capacity is 8.0 liters. Test the radiator cap: it must hold 0.9 bar (13 psi) per the spec on page 88; replace if it fails. Verify the thermostat opens and the water pump impeller is intact before suspecting head gasket issues.
Manual Section: Engine Troubleshooting - GeneralClutch slips under heavy load with burning smell when pulling uphill or towing
Adjust the clutch pedal free play per the Clutch section at page 221. If adjustment doesn't stop the slip, remove the assembly and measure the clutch plate: outside diameter should be 275 mm (10.827 in.) per the spec on page 222. Inspect the flywheel face and pressure plate for oil contamination from a rear main seal leak before ordering parts.
Manual Section: Clutch TroubleshootingPower steering requires heavy effort to turn, especially at low ground speed
Check the power steering fluid level and refill if low; total capacity is 1.8 liters (1.9 U.S. qts.). Inspect the steering pump drive belt for wear or slippage. Purge air from the system by cycling the steering lock-to-lock several times with the engine idling. If stiffness remains, trace the hydraulic circuit through the Steering section at page 773.
Manual Section: Steering TroubleshootingPTO shaft won't rotate or engages and immediately stalls under implement load
Verify the PTO control lever locks fully into the engaged detent. Check the transmission and hydraulic fluid level; shared system capacity is 42.0 liters (11.1 U.S. gal.). Inspect the hydraulic filter for restriction; first change is at 50 hours. If pressure confirms but the shaft won't spin, trace the fault in the PTO section at page 607.
Manual Section: PTO TroubleshootingFrequently Asked Questions
Torque specs for engine bolts on Case IH DX55?
The manual provides metric bolt torque specifications for various engine components on the Case IH DX55. For example, connecting rod cap bolts should be torqued to 49-54 N⋅m (36-40 ft. lbs.), main bearing retaining bolts to 49-54 N⋅m (36-40 ft. lbs.), and cylinder head bolts to 98-103 N⋅m (72-76 ft. lbs.). Flywheel retaining bolts require a torque of 68-78 N⋅m (51-58 ft. lbs.).
