Tracking down drive motor issues on your loader just got easier with this 214-page Case 40xt service manual pdf, covering the complete XT series including the 60 and 70 skid steers. You get complete hydraulic schematics detailing charge pressure flows, clear wiring diagrams for isolating electrical faults, and high-quality exploded views of the hydrostatic pump assemblies. Open up a full troubleshooting section that walks you through exactly what to do when one transmission works correctly and the other fails. Verify your main relief pressure is hitting exactly 3000 psi (20,700 kPa) before topping off the 50.2-liter hydraulic system. Stop ripping apart the wrong components to fix machine creep. Download this bookmarked file directly to your shop tablet, click the section you need, and get your machine back to pushing dirt.

Case 40XT / 60XT / 70XT Common Problems This Manual Covers
Case 40XT-70XT main relief valve won't adjust to correct hydraulic pressure setting, bucket lifts weak
Check the pressure checks procedure. Install a gauge inline and run the engine at full throttle; main relief pressure should read 20,700 kPa (207 bar, 3000 psi) per page 162. If it won't reach spec, the relief cartridge is worn; replace it rather than keep forcing the adjustment screw.
Manual Section: Hydraulic System Pressure ChecksEngine won't start or runs rough in cold weather, water suspected in fuel
Drain the fuel tank, which holds 83.3 litres (22 U.S. gallons) per the specification on page 12, and check for water settling at the bottom of the tank. Replace the fuel filter and refill with fresh diesel before attempting a restart. Store the fuel container outside and away from heat so condensation can't form and contaminate the tank again.
Manual Section: Electrical System TroubleshootingHydraulic hoses or lines worn through near sharp edges or moving parts, oil spraying under pressure
Trace the failed hose against the hydraulic schematic to confirm correct routing before replacing it. Reroute the new line clear of the chain case and cylinder rods, and secure it with new clamps every 12 to 18 inches. Refill the system to its 50.2 litre (13.3 gallon) capacity per page 12 and bleed air before testing.
Manual Section: Hydraulic System Troubleshooting (General)Auxiliary hydraulic flow won't engage from the foot pedal, attachment doesn't respond
Check the troubleshooting procedures for auxiliary flow faults before tearing into the valve. Verify the auxiliary relay and pedal switch close at idle, then check for full pedal travel; binding linkage often mimics a bad flow valve. Test pressure against the 20,700 kPa (3000 psi) main relief spec on page 162 to rule out a system-wide loss.
Manual Section: Hydraulic System Troubleshooting (General)One drive side works correctly while the other doesn't, machine pulls to one side p. 202
Start with the hydrostatic troubleshooting checks for one side working and the other not. Confirm both drive motors share equal charge pressure, then test circuit relief on the weak side; it should hold at 34,500 kPa (5004 psi) per page 202. A low reading usually points to a worn relief valve or a damaged drive motor.

What are the replacement specifications for Main relief valve?
The Main relief valve controls the hydraulic system pressure, with a Main Relief Pressure specification of 20,700 kPa (207 bar) (3000 psi). If the pressure setting is not as specified, or if the valve begins to open at 183 bar (2400 psi) or less when completely open, the main relief valve is considered damaged and must be replaced. Refer to page 45 or 122 for the location of the main relief valve and page 166 for further testing procedures.
How do you fix case 40XT-70XT main relief valve won't adjust to correct hydraulic pressure setting, bucket lifts weak?
Check the pressure checks procedure. Install a gauge inline and run the engine at full throttle; main relief pressure should read 20,700 kPa (207 bar, 3000 psi) per page 162. If it won't reach spec, the relief cartridge is worn; replace it rather than keep forcing the adjustment screw.
