Part of the Case Repair Manuals.
The 570LXT is Case's loader landscaper, and it earns its keep on rough duty cycles that punish the shuttle, the axles and the loader pins. This is the real factory service manual, part 7-50773, 1,125 pages covering the 4-390 diesel engine, fuel, electrical, steering, power train, brakes and the full hydraulic system. Whether you are chasing a shuttle that hesitates on forward or reverse, a leaking rear PTO seal, or just setting fluid capacities and idle speeds before a job, it is here in factory order with the specs and torque values the machine was built to.

Case 570LXT Common Problems This Manual Covers
Slow forward or reverse engagement after the machine has sat (shuttle hesitation)
Start at the transmission strainer screen and clean it, then check the modulator and control valve operation and the shuttle pressures against spec. The Carraro shuttle is sensitive to a clogged strainer or a lazy modulator, and the power train section gives the pressure test points and adjustment steps to isolate and correct it.
Manual Section: Power Train3-point hitch or rear PTO output seal leaking into the rear housing
Inspect the rear PTO output seal, which is specific to the 570LXT rear configuration, and replace it before contamination reaches the rear housing oil. The power train and hydraulics sections cover the seal replacement and the correct rear housing fluid level and capacity.
Manual Section: Power TrainRapid Carraro planetary wear or king pin damage on the front axle
This is almost always a lubrication problem, a missing or sheared lower kingpin grease zerk starves the joint. Restore the grease point, follow the daily lubrication schedule, and inspect the planetary and kingpin for wear before further damage. The power train section covers the axle service and the greasing intervals.
Manual Section: Power TrainAccelerated wear on boom pivot and bucket pins under heavy landscape work
Heavy loader duty cycles wear the boom pivot and bucket pins faster than lighter use, so keep the pins greased on schedule and check pin and bushing clearance regularly. The hydraulics and general sections cover the loader linkage service and the wear limits to replace against.
Manual Section: HydraulicsFrequently Asked Questions
What does Case part number 7-50773 cover?
It is the full factory service manual for the Case 570LXT Loader Landscaper, 1,125 pages covering the 4-390 diesel engine, fuel, electrical, steering, power train, brakes and the hydraulic system with fluid capacities and repair procedures.
My 570LXT is slow to engage forward or reverse after sitting, where do I start?
That shuttle hesitation usually traces to a dirty transmission strainer screen or a modulator/control valve issue. The power train section covers the transmission, shuttle and the pressure checks to isolate it.
What do error codes E01 and E02 mean and how do I reset the display?
The electrical section covers the instrument and error code display, what the fault codes indicate, and the reset and diagnostic procedure.
What are the front axle bolt torque values?
The General section lists the standard and specific torque values, including the four wheel drive front axle, along with the fluid capacities for the axle and planetaries.
Is this the same manual a Case dealer uses?
It is the factory service manual (part number 7-50773), the same step by step repair, specification and torque data the 570LXT was built and serviced to.
