Case 9030B, 9040B, 9045B Common Problems This Manual Covers
Case 9040B excavator shuts off suddenly with Low Oil Pressure fault, will not restart
Check oil pressure at operating temperature: a warm engine at rated speed should read 2.07 to 3.45 Bar (30 to 50 psi). Verify crankcase level at 23.2 liters (6.1 US gallons). If oil level is adequate, bleed the fuel system; new injector opening pressure must be 205 to 213 Bar (2968 to 3084 psi) per page 28.
Manual Section: Engine Oil Pressure TroubleshootingEngine turns over slowly or fails to crank, electrical system at fault
Inspect both 12-volt batteries: cold cranking capacity must be 800 amperes at -17°C (0°F), load-tested at 400 amperes. Check all fuses for breakage and corrosion per page 82. Test the 24-volt DelcoRemy starter motor for voltage drop under load. Confirm alternator output reaches 65 amperes at rated engine speed.
Manual Section: Battery System Charging & Fluid TroubleshootingHydraulic leaks return immediately after seal and connection repairs, fittings still weeping p. 157
Always install new oil seals, O-rings, and gaskets as specified on page 7. Reusing old seals is the leading repeat-leak cause. After reassembly, verify main relief pressure at 318 ±20 Bar (4612 ±290 psi) and pilot relief at 40 ±3 Bar (580 ±43 psi). The total hydraulic system holds 224 liters (59 US gallons); check level after any seal work.
Manual Section: Hydraulic System Pressure Testing & AdjustmentTrack tension out of spec, shoe bolts loose, pin and bushing wear accelerating
Inspect track tension and adjust per service procedures. Torque all track shoe cap screws to 555 to 685 lb-ft (755 to 930 Nm) per page 102. Check pin and bushing condition at each service interval. Consult the exploded parts view to identify worn components before disassembly.
Manual Section: Tracks, Rollers, and IdlersAir cleaner clogged, engine losing power and running rough under heavy load p. 82
Remove and inspect the air cleaner element. Clean or replace it if dirty or damaged, per page 82. A restricted air filter starves combustion and produces black exhaust smoke. After replacement, confirm the engine recovers rated output of 133 kW (178 hp) at 2200 rpm per the engine specifications on page 27.
Manual Section: Electrical Specifications and TroubleshootingFrequently Asked Questions
What fluids and capacities does this machine require?
The 9040B Excavator requires specific fluids and capacities. For instance, the Engine Crank Case Capacity is 23.2 liters (6.1 US gallons), the Fuel Tank is 310 liters (82 US gallons), and the Total Hydraulic System Capacity is 224 liters (59 US gallons). Recommended lubricants include CASE MS-1210 TCH FLUID for the Hydraulic System and API GL-4, SAE 90 for Final Drive and Swing Drive Lubricants.
How to troubleshoot engine won't start?
To troubleshoot an engine that won't start, first ensure the "ELEC. PROBLEM" message is not indicated on the monitor. If it is, refer to trouble No. 10. If not, check if controlling engine rotation is possible. The manual provides a detailed flow chart starting on page 97 for "Problem Description (No. 10) Engine does not start even though the message "ELEC. PROBLEM" is not displayed."
What are the hydraulic system specifications?
The hydraulic system specifications include a Kawasaki K3V112DT-1M4R pump with a displacement of 96.5 cm³/rev x 2 and a maximum working pressure of 343 (travel) Bar (4980 psi). The main relief standard is 318 ±20 Bar (4612 ±290 psi), and the pilot relief is 40 ±3 Bar (580 ±43 psi). The hydraulic oil test temperature is 45 - 55°C (113-131°F).
What torque specifications are listed?
The manual lists various torque specifications for cap screws and nuts. For Cap Screws, an M12 size requires 58.8 Nm (43.4 lb-ft) and an M20 requires 274.0 Nm (202.4 lb-ft). For Socket Head Cap Screws, an M12 requires 78.4 Nm (57.8 lb-ft) and an M20 requires 343.0 Nm (253.1 lb-ft). Special torques for track components are also provided, such as Track Shoe Cap Screws at 555 to 685 lb-ft (755 to 930 Nm).
