Case 40 XT, 60 XT, 70 XT Common Problems This Manual Covers
Case 40 XT engine fails to start or runs erratically with sputtering after sitting in storage
Drain the fuel tank and check the water separator bowl for standing water before cranking again. The fuel tank holds 84 Ltr., so top off with fresh diesel after draining contaminated fuel completely. Replace the water separator element and bleed air from the fuel lines at the injector pump. Check wiring at the fuel solenoid pull in relay per the electrical fuel system troubleshooting if the engine still won't fire.
Manual Section: Electrical Fuel System Components TroubleshootingHydraulic system pressure drops below 124 bar during operation, bucket response feels weak
Hook up a flowmeter and run the pressure and flow tests for the loader circuits described. Check main relief pressure against the 20,700 kPa spec listed on page 162; if it reads more than 3.8 L/min (one gpm) below the baseline flow at the same pressure noted on page 167, the pump or seals are leaking internally and need teardown.
Manual Section: Hydraulic Pressure & Flow Tests (Loader Circuits)Unable to maintain throttle at 2000 rpm under load, engine bogs down on heavy lift
Check the air filter restriction indicator first; a clogged element chokes intake before governor linkage ever gets blamed. Inspect the governor linkage for binding or a stretched cable, and verify the fuel injector pump timing is set correctly. Reference the engine oil pressure and coolant temp sensor checks starting to rule out a false shutdown signal masquerading as power loss.
Manual Section: Electrical Instrument Panel & Sensor TroubleshootingHydraulic pressure loss during auxiliary flow control use, attachments lose power intermittently
Run the auxiliary circuit flowmeter test while cycling the high flow switch to isolate whether the drop is circuit-specific or system-wide. Check the high flow switch wiring and hydraulic coupler connections per the hydraulic control troubleshooting section. Torque any loose coupler fittings and verify the circuit relief valve holds the 20,700 kPa main relief spec on page 162.
Manual Section: Electrical Hydraulic Control TroubleshootingOne side of the drive works while the other doesn't, machine pulls hard to one track or wheel
Start with the hydrostatic system general troubleshooting table to narrow down pump versus motor versus linkage. Check charge pressure and flow on the affected side against the good side using the checks; a charge pressure gap points to a worn hydrostatic pump. Verify the hydrostatic drive pump doesn't exceed its 345 kPa maximum pressure spec, and inspect the control linkage for a bent or disconnected rod.
Manual Section: Hydrostatic System General TroubleshootingReversible standard tires wearing unevenly and rubbing against the frame during turns
Check tire mounting direction and rotation pattern against the 12x16.5 tire dimension spec, since these reversible tires must be rotated on schedule to even out wear. Inspect the frame clearance area for scuffing that indicates the tire is riding too close, and check wheel bearing play. Re-torque wheel lug nuts to spec and confirm tire pressure matches the sidewall rating before returning the machine to service.
Manual Section: Presentation: Technical Specifications p. 10Frequently Asked Questions
How do you reset the hydraulic control valve on Case 40XT, 60XT, and 70XT skid steers?
The manual provides procedures for "Centering the servo piston" and "Hydraulic Neutral Adjustment" to address issues with the hydraulic control valve. Centering the servo piston involves connecting a hose between ports or removing a restriction orifice, then adjusting the servo screw until the tires begin to rotate in both directions, centering the screw between these points. The hydraulic neutral adjustment requires raising the unit, releasing brakes, and using a jumper wire for the seat switch, then adjusting the servo adjustment bracket based on tire rotation. p. 203
What is the purpose of the spring in the hydraulic control valve for Case XT series?
Springs in the hydraulic control valve serve several purposes, including maintaining the main spool in a closed position within the main relief valve, where a small spring force keeps it closed until oil pressure exceeds its setting. In circuit relief valves, a spring holds a poppet against a seat, requiring hydraulic force to open it. Additionally, a spring-centered mechanism in the hydrostatic pump's servo control system returns the servo control to a neutral position. p. 47
How do you reset the hydraulic control valve spring on Case 40XT?
To adjust the hydraulic control valve spring, specifically the servo piston centering spring, you need to remove the cap and external sealing nut, then the bolts retaining the servo piston cover. Rotate the piston end cover off the servo adjusting screw and then tighten or loosen the centering spring lock nut until all looseness is removed. The lock nut must be positioned just tight to the spring. p. 205
What is the fuel tank capacity for Case 40XT, 60XT, and 70XT skid steers?
The fuel tank capacity for these skid steers is 83.3 litres (22 U.S. gallons). It is recommended to fill the tank at the end of the daily operating period to prevent condensation. p. 12
