This Bobcat 320 & 322 G Series Excavator Service Manual goes far beyond routine maintenance. It provides the complete disassembly and assembly procedures for every major component — hydraulic cylinders, control valves, pumps, motors, swivel joints, swing frames, and the undercarriage. Each procedure includes step-by-step instructions with photographed or illustrated references, torque values, and service limits. The electrical system section includes a full wiring schematic for the 320 and 322, and the hydraulic section includes a detailed schematic of the control valve, manifold, and circuit routing. The troubleshooting charts for the hydraulic circuit, cylinder circuit, swing circuit, and travel circuit help isolate faults before disassembly. Engine reconditioning is covered separately for early and later serial ranges, with cylinder head servicing, piston and connecting rod service, crankshaft and bearing inspection, and complete engine specifications.

What This Manual Enables You To Do

With this Bobcat 320 & 322 G Series Excavator Service Manual, a qualified technician can perform full machine overhauls, not just filter changes. You can remove and reinstall the engine, rebuild hydraulic cylinders, service the hydraulic control valve section by section, replace travel motor components, adjust track tension, repair the swing motor, replace boom and arm bushings, service the swivel joint, and diagnose electrical faults using the factory wiring schematic. The manual gives you the correct torque values, oil capacities, pressure settings, and adjustment clearances so every repair is done to specification.

The Bobcat 320 and 322 G Series are compact excavators used in construction, landscaping, and utility work. When a hydraulic cylinder leaks or a travel motor fails, downtime is expensive. Having the correct service procedures and specifications on hand means you can order the right parts, perform the repair correctly the first time, and get the machine back to work. The manual covers serial numbers from 223911001 and 224011001 upward, so it applies to a wide production range of G Series machines.
