Part of the Yanmar Repair Manuals.
Air trapped in the pump after a hose change will make a ViO75 groan under load, and the fix is a specific bleeder procedure, not more cranking. This Yanmar ViO75 (ViG3 series) excavator service manual settles that kind of question with factory procedures for the hydraulic system, control valves, piston and gear pumps, travel and swing motors, and the 4TNE98-EBVA diesel engine.
Service Standards chapters set wear limits for rubber and steel crawler undercarriages, hydraulic cylinders, and front attachment pins, so you can measure a worn part and know whether it stays or goes. Technical Data adds full specifications, weights of main parts, and lifting capacities for standard and long arm machines.
The full 556-page book travels as one PDF on a phone or laptop, so the answer is wherever the machine stopped, in the cab or beside the track frame. A crew waiting on parts is bad enough; waiting on information is optional.
