Case IH JXU75, JXU85, JXU95, JXU105, JXU115 Common Problems This Manual Covers
Loss of hydraulic or lift power during heavy lifting
Weak lift or hydraulic power under load usually traces to the hydraulic pump, a low relief setting or a worn control valve. Check the system pressure and flow against spec, inspect the relief and the fluid level and condition, then service the pump if output is low. The hydraulic systems section gives the test points and pump procedure.
Manual Section: Hydraulic SystemsEngine stalls unexpectedly under load
A stall under load on the F4CE diesel is most often fuel delivery, a clogged filter or an air intake restriction. Change the fuel and air filters, check supply and injection delivery, and confirm the idle and rated speeds. The engine section covers the fuel and injection service and the speed settings.
Manual Section: EngineLoss of power steering or heavy steering
Heavy or lost steering points to the steering pump, a low relief or air in the system. Check the fluid level and condition, bleed the system, and test the steering pump and relief pressure against spec. The steering section covers the pump, valve and the pressure checks.
Manual Section: SteeringFrequently Asked Questions
What does Case IH part number 87679936A cover?
It is the full factory service manual with supplement for the Case IH JXU75, JXU85, JXU95, JXU105 and JXU115 tractors, 1,538 pages covering the F4CE 4.5 litre diesel, clutch, transmissions, front and rear drive, PTO, brakes, hydraulics, steering, cab air conditioning and the electrical system.
My JXU loses lift or hydraulic power under a heavy load, where do I start?
Loss of lift power under load usually points to the hydraulic pump, the relief setting or a worn control valve. The hydraulic systems section covers the pump, the pressure and flow checks and the relief settings to isolate it.
Does one manual cover all five JXU models?
Yes. The JXU75, JXU85, JXU95, JXU105 and JXU115 are covered together, with the per model engine ratings and any model specific differences called out within each procedure.
Which engine is in the JXU series and what power does each model make?
All five use the F4CE 4.5 litre four cylinder diesel. Output runs from 56 kW (76 hp) on the JXU75 up to 83 kW (113 hp) on the JXU115, with the exact rating per model in the engine section.
Is this the same manual a Case IH dealer uses?
It is the factory service manual with supplement (part number 87679936A), the same step by step repair, specification and torque data the JXU tractors were built and serviced to.
