Looking for the Kubota LA764 workshop manual PDF? These 61 factory pages (OEM #9Y111-07120) cover the LA764 Front Loader from safety and specs through full disassembly and reassembly. The hydraulic schematic traces circuit flow across all six control valve positions: neutral, up, down, floating, roll-back, and dump. Eight pages of tightening torques run from general hardware through hydraulic fittings and adapters. Fifteen servicing pages walk through loader removal, control valve teardown, cylinder overhaul, and frame work, backed by a maintenance checklist with intervals from daily to 50-hour points. Set the M16 main frame bolts to 226 N-m, the M12 sub frame hardware to 90.2 N-m, and fill the transmission case to 40.0 L before startup. Stop chasing hydraulic faults on guesswork. Every section is bookmarked, so you can jump straight to the page you need on a tablet at the machine.

Kubota LA764 Common Problems This Manual Covers
Kubota LA764 boom moves in the wrong direction or bucket does not respond normally to control inputs p. 42
Inspect the hydraulic hose routing against the schematic on page 30. Reconnect any reversed lines. Check the transmission case hydraulic fluid level and fill with up to 40.0 L of fluid if low. Torque 9/16 UNF flare nuts to 22 to 25 N-m.
Manual Section: ServicingLoader becomes locked up in the down position or overall boom motion is severely restricted p. 44
Test the relief valve setting pressure on page 44. Adjust the valve to hold 17.1 to 18.1 MPa. Verify the control valve spool is not stuck. Check the cylinders for internal leakage and replace damaged seals to restore the 4.0 sec lifting time.
Manual Section: ServicingQuick attach parts bind during attachment changes or latching handles feel excessively tight p. 54
Clean dirt and debris from the latch area and grease the pivot points. Torque the grease fittings to 4.1 to 6.7 N-m as specified on page 21. Measure the clearance between the boss and the nut when fixing the pin, keeping it within 2 to 3 mm.
Manual Section: ServicingBoom structure or center support bar appears bent and frame loads unevenly during operation p. 45
Check the main frame mounting bolts for loose connections. Torque the M16 main frame mounting bolts to 226 N-m using the specifications on page 45. Measure the piston rod for straightness and replace it if the bend exceeds the 0.25 mm allowable limit.
Manual Section: ServicingFrequently Asked Questions
What are the torque specs for Kubota LA764 loader mounting bolts?
Main frame mounting bolts (M16) tighten to 226 N·m (23.0 kgf·m, 166 lbf·ft). The M16 sub frame mounting bolts and nuts take that same 226 N·m (23.0 kgf·m, 166 lbf·ft). The M12 sub frame bolts and nuts drop to 90.2 N·m (9.20 kgf·m, 66.5 lbf·ft).
What is the correct procedure for removing and reinstalling a Kubota LA764 front loader?
To remove the loader, lift the boom until the stands can turn, stop the engine, and pull the spring pins (2) holding the stands to the boom. Move the stands outward, align the holes, then slide them inward and fit the spring pin as shown on page 46. To reinstall, ease the tractor between the loader side frames (1) until the rear of both side frames touches the main frames (2), then connect the four hoses (3) with couplers to the control valve fittings as shown on page 48.
How to torque Kubota LA764 loader bolts
Set the main frame mounting bolts (M16) to 226 N·m (23.0 kgf·m, 166 lbf·ft). The M16 sub frame bolts and nuts use that same figure. For the M12 sub frame bolts and nuts, back off to 90.2 N·m (9.20 kgf·m, 66.5 lbf·ft).
What are the replacement specifications for hydraulic fluid?
Use KUBOTA UDT or SUPER UDT fluid* in the hydraulic system. The transmission case feeds the front loader hydraulics and holds 40.0 L (10.6 U.S. gals, 8.80 Imp. gals).
