Part of the Kubota Repair Manuals.
This is the Kubota Shop Manual for the LA524AU-B, LA714AU-B, and LA854AU-B front loaders, a 68 page PDF covering all three models in one document. It moves through loader information and specifications, the general section with identification, lubricants, and tightening torques, the mechanism section for the hydraulic circuit and control valve assembly, and the servicing section with troubleshooting and repair.With it you can diagnose weak or sticking loader functions, service the boom and bucket cylinders and control valve, dismount the loader from the tractor, and reset fittings and mounting hardware to factory torque. It also covers the optional third function valve and the self-leveling parallel linkage.Reference figures include lift capacities to maximum height of 400 kg, 600 kg, and 800 kg across the three models, a main frame mounting bolt torque of 226 N-m, and a relief valve setting of 17.1 to 18.1 MPa.

Kubota LA524AU-B, LA714AU-B, LA854AU-B Common Problems This Manual Covers
Loader stalls on combined moves
The loader can stop or hesitate when raising and curling at the same time, pointing to the control valve metering. The mechanism section explains the control valve assembly structure and the boom and bucket cylinder control.
Manual Section: Mechanism p. 27Bucket will not lower normally
A bucket that only lowers while another function is used suggests a sticking spool or a control valve fault. The servicing section troubleshooting helps isolate the lower circuit before disassembly.
Manual Section: Servicing p. 48Loader drifts or feels spongy
Some bleed-down after shutdown is normal, but persistent weakness or drift can mean low fluid, internal leakage, or air in the system. The servicing checks help you tell normal from a real fault.
Manual Section: Servicing p. 48Weak or intermittent hydraulics
Functions that fade under load often come from low fluid, a clogged filter, leaking hoses, or low system pressure. The servicing section covers checking the relief valve, set to 17.1 to 18.1 MPa on the LA714AU-B.
Manual Section: Servicing p. 48Loose main frame mounting hardware
Loader mounting and fitting hardware works loose over time and must be reset to spec. The general section lists tightening torques, including the main frame mounting bolt and nut at 226 N-m.
Manual Section: General p. 16Twisted loader arms or support bar
Side loading or overload can bend loader arms or the support crossbar. The servicing section covers checking, disassembling, and servicing so you can inspect and repair the structure.
Manual Section: Servicing p. 48Frequently Asked Questions
Which loaders does this manual cover?
It covers the Kubota LA524AU-B, LA714AU-B, and LA854AU-B front loaders together in one shop manual, with shared and model-specific specifications, mechanism, and servicing information.
Do the lift capacities differ by model?
Yes. Lift capacity to maximum height is 400 kg on the LA524AU-B, 600 kg on the LA714AU-B, and 800 kg on the LA854AU-B. The information section lists the full loader and bucket specifications. p. 2
Does it give the hydraulic relief valve pressure?
Yes. The servicing section covers checking and adjusting the hydraulics, including the relief valve setting pressure of 17.1 to 18.1 MPa on the LA714AU-B. p. 48
Are torque specs for fittings and mounting included?
Yes. The general section covers tightening torques for bolts, plugs, and hydraulic fittings, including the main frame mounting bolt and nut at 226 N-m and the various UNF and NPT fitting values. p. 16
