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. Instant PDF download, print as needed.
