Part of the Kubota Repair Manuals.
This workshop manual covers the Kubota LA525 and LA765 front loaders, the factory service book (publication 9Y111-10142) for owners and mechanics servicing these attachments. Its 80 pages walk through how the loaders work and how to repair them, not just how to run them.
Content is organized into Information, General and Front Loader sections. You get loader and bucket specifications, loader identification, lubricant and tightening-torque tables, the hydraulic circuit, hydraulic block and control valve assembly with structure and operation, plus troubleshooting and servicing specifications. Torque figures, relief-valve pressures and wear limits are called out throughout.
These loaders mount to Kubota L2501, L3301, L3901 and L4701 tractors, and the manual reflects that range. Delivered as a searchable, printable PDF, it is the reference for setting mounting bolts correctly, chasing a hydraulic fault, or rebuilding a cylinder to spec.
