Part of the Kubota Repair Manuals.
This is the Kubota LA714AU-C front loader workshop manual, publication 9Y111-07800, a 60-page PDF with a full text layer. It covers the LA714AU-C loader from identification and lubricants through the hydraulic circuit, the control valve assembly with its boom and bucket cylinder controls, the optional third function valve, and the self-leveling parallel linkage.The Servicing section holds the hands-on material: troubleshooting charts, servicing specifications, tightening torques, and the procedure for dismounting the loader from the tractor. Verified figures include the main frame mounting bolt torque, hydraulic hose fitting torques, the solenoid valve resistance, and the main relief valve setting pressure, so a repair can be measured against factory values.Buyers get an instant PDF download that opens on a phone, tablet, or shop computer and prints cleanly, keeping the torque tables and troubleshooting charts on hand at the bench.

Kubota LA714AU-C Common Problems This Manual Covers
Loader will not raise or curl under load
No response under load usually means low fluid, air in the system, a leaking hose, or a valve or pump issue. The troubleshooting charts step through these checks to isolate the fault.
Manual Section: Troubleshooting p. 45Loader drifts down after lifting
Loss of holding power after a lift points to internal cylinder leakage, control valve leakage, or worn seals. The checking and servicing procedures show how to inspect and rebuild the cylinders.
Manual Section: Checking, Disassembling And Servicing p. 50Jerky or slow loader operation
Contaminated or low oil, a clogged strainer, or air ingress makes the loader hesitate. The control valve assembly coverage explains the boom and bucket cylinder controls so the cause can be traced.
Manual Section: Control Valve Assembly p. 29Hydraulic leaks at hoses and fittings
Aged seals, loose couplers, or over-tightened fittings cause weeping at the connections. The hydraulic fittings torque table gives the flare nut figures so joints are sealed without damage.
Manual Section: Hydraulic Fittings p. 22Excessive play or loose attachment
Sloppy bucket or loader movement often comes from worn pins, bushings, or linkage hardware. The servicing specifications list the wear limits so worn parts can be identified and replaced.
Manual Section: Servicing Specifications p. 46Self-leveling not tracking correctly
Poor bucket leveling can come from the parallel linkage or the port relief valve being out of adjustment. The self-leveling section explains the linkage and relief valve so it can be checked.
Manual Section: Self-Leveling p. 42Frequently Asked Questions
