Part of the Yanmar Repair Manuals.
All 770 pages of this Yanmar V80 Wheel Loader Service Manual cover every system on your compact loader: the full embedded Deutz TCD 2.9 L4 workshop manual, travel hydraulics setting instructions, and a complete electrics section with cable colors, fuse assignments, and relay charts. You get hydraulic circuit diagrams for both Parallel-Kinematic and Z-Kinematic configurations, full vehicle wiring schematics, and a diagnosis section packed with SerDia 2010 SPN/FMI error codes. Inside the setting instructions: A4VG045DA1 displacement pump specs, A6VM DA motor calibration, and Hydromatik tightening values for the entire travel hydraulic system. Torque the M68x2 guide bushing on the 63mm cylinder to 290-335 Nm; M8 headless screws get 25 Nm. Your machine doesn't care about guesses. Bookmarked for instant navigation: pull it up on your tablet, jump to the schematic, and start turning wrenches.
