Name: Link-Belt 75 & 80 Spin Ace Tier III Service Manual with Wiring Diagrams
Author: Link-Belt

Relief valve settings, pump flow control and circuit routing for these machines are things only the factory can settle, and this 756-page Link-Belt 75 and 80 Spin Ace Tier III service manual PDF is where the factory puts them on record for both hydraulic excavators. Travel, swing, boom and bucket circuits are traced port by port in the hydraulic section, down to pilot hose connections and backup circuits. Wiring and harness diagrams cover the monitor display and engine control, while the maintenance section, by far the largest part of the book, takes you from pressure checks through full disassembly. On the 80, run a 10 µm fuel pre-filter ahead of the 4 µm main filter and a 6 µm return element in the hydraulic tank. Some days it is just you, the machine, and nobody to call. This bookmarked, keyword-searchable PDF rides along on your laptop to whatever site the excavator is working.
