Case IH D35–DX45 Common Problems This Manual Covers
Case IH D35 hydraulic system loses pressure after hot operation and implement fails to lift. p. 623
Inspect the hydraulic schematic to trace the pressure lines. Verify pump capacity reaches 37.1 lpm (9.8 gpm). If output drops below specification, replace the faulty pump and torque the new retainers to 22 to 28 Nm (16 to 20 ft. lbs.) using the guide on page 607.
Manual Section: Hydraulic System TroubleshootingEngine stalls under heavy load on steep slopes and produces excessive black exhaust smoke. p. 119
Check the fuel injectors using the procedures on page 119. Test the injection pressure and verify it reaches 147 bar (2150 psi) as detailed on page 219. If pressure is low, adjust the setting to 146 bar (2150 psi) or replace the injector assembly to restore clean combustion.
Manual Section: Engine TroubleshootingTractor loses forward momentum during gear changes and transmission fails to engage gears smoothly. p. 261
Measure the clutch pedal free-travel and confirm it measures between 19 mm and 30 mm as shown on page 257. If adjustment fails to fix the slip, replace the complete single clutch assembly and tighten the mounting bolts to 22 to 28 Nm (16 to 21 ft. lb.).
Manual Section: Clutch TroubleshootingEngine fails to crank in freezing weather and starter motor emits a rapid clicking noise. p. 119
Test the battery voltage and inspect the wiring diagram for loose ground connections. Remove the starter and bench test it to ensure the motor reaches a no load speed of 4000 RPM as specified on page 1011. Clean all terminals before reinstalling the unit.
Manual Section: Engine TroubleshootingFrequently Asked Questions
Torque specs for engine bolts on Case IH D35
For the Case IH D35, connecting rod cap bolts should be torqued to 49-54 N⋅m (36-40 lbs. ft.). Main bearing retaining bolts also require a torque of 49-54 N⋅m (36-40 lbs. ft.). Cylinder head bolts should be tightened to 98-103 N⋅m (72.3-76 lbs. ft.).
How to reset hydraulic pressure on Case IH D45
To adjust the hydraulic pressure on a Case IH D45, you need to adjust the relief pressure setting by adding or removing shims from the relief valve. The specified pressure reading for D45 models should be 172 bar (2500 psi). Each 0.3 mm (0.012 in.) shim change will adjust the pressure by approximately 10 bar (150 psi).
What are the replacement specifications for Hydraulic pump?
The hydraulic pump is a gear type pump. If troubleshooting indicates a faulty pump, it should be replaced with a new assembly, as only the shaft seal and internal O-rings are serviceable parts. The pump capacity is 37.1 lpm (9.8 gpm) at an engine speed of 2800 rpm.
What are the replacement specifications for Clutch plate assembly?
The clutch plate assembly is serviced as a complete unit, with overhaul limited to resurfacing the flywheel and replacing the entire clutch assembly if damaged. The clutch disc lining should be replaced if worn to less than 6.9 mm (.27 in.) on D35 and D40 models, or 7.2 mm (.28 in.) on D45 models, from the top of the rivet head.
