Bobcat 320 & 320L Excavator PDF Repair and Service Manual (S/N 223811001 & Above)
The Bobcat 320 and 320L Compact Excavators are engineered to deliver dependable hydraulic performance, precise control and excellent maneuverability for contractors working in construction, landscaping, utility installation and property development. While both models share the same proven platform, the 320L features an extended undercarriage that provides improved stability during lifting and digging operations. This OEM factory service manual is specifically written for machines with serial numbers 223811001 & Above, ensuring every repair procedure, specification and illustration matches the correct production configuration.
Designed for trenching, foundation excavation, drainage projects, grading and general earthmoving, the Bobcat 320 and 320L combine a rugged crawler undercarriage with a responsive hydraulic system for smooth boom, arm and bucket operation. Their compact dimensions allow operators to work efficiently in restricted spaces while maintaining excellent breakout force and lifting performance. Both excavators are compatible with numerous work attachments including buckets, hydraulic breakers, augers and grapples, making them versatile machines for a wide range of jobsite applications.
As machine operating hours increase, components such as hydraulic pumps, control valves, swing drives, travel motors, final drives and electrical systems require accurate diagnosis before repairs are carried out. The official Bobcat Factory Service Manual provides dealership-level procedures covering inspection, troubleshooting, hydraulic pressure testing, complete disassembly, repair, adjustment and operational verification using OEM service specifications.
