Part of the Kubota Repair Manuals.
This is the Kubota LA714AU and LA854AU front loader workshop manual, publication 9Y111-04020, a 55-page PDF with a full text layer covering both loader models. It documents loader identification and lubricants, the self-leveling parallel linkage and port relief valve, the hydraulic circuit and block, and the four-position bucket control valve assembly.The Servicing section carries the repair material: troubleshooting charts, servicing specifications, tightening torques, and the procedure for dismounting the loader from the tractor. Model-specific figures include the boom and bucket cylinder torques for each loader, the main frame bolt torque, relief valve setting pressures, and the piston rod bend limit, so a repair can be checked against factory numbers.Buyers download the manual instantly as a PDF that opens on a phone, tablet, or shop computer and prints cleanly, keeping the torque tables and troubleshooting charts ready at the bench.

Kubota LA714AU, LA854AU Common Problems This Manual Covers
Slow, weak, or jerky loader movement
Dirty or low oil, a clogged filter, or internal leakage makes the loader hesitate under load. The troubleshooting charts step through the checks to find where the pressure is being lost.
Manual Section: Troubleshooting p. 38Bucket or boom will not lower normally
A hard catch near float or a bucket that will not drop points to a sticking valve spool or a control valve fault. The four-position bucket control valve coverage explains its operation.
Manual Section: Control Valve Assembly p. 25Support bar or frame twisted
Uneven attachment loading or a side disconnect event can twist the loader linkage or bend the support bar. The dismounting procedure covers correct attachment and support to avoid this.
Manual Section: Dismounting Front Loader From Tractor p. 38Mounting bolts working loose
The main frame and sub frame hardware can loosen under vibration and heavy use. The Tightening Torques figures give the main frame bolt value so fasteners are reset to spec.
Manual Section: Tightening Torques p. 38Self-leveling not holding the bucket level
Poor bucket leveling ties to the parallel linkage or the port relief valve being out of adjustment. The self-leveling coverage explains the linkage and relief valve setting.
Manual Section: Self-Leveling p. 25Hydraulic leaks at hoses and fittings
Aged seals, loose couplers, or damaged hoses cause weeping around the connections. The hydraulic circuit and fitting coverage shows oil flow and the correct fitting torques for sealing joints.
Manual Section: Hydraulic Circuit p. 25Frequently Asked Questions
