Together, these technical chapters provide service personnel with a thorough, standardized guide for maintaining and overhauling the Bobcat S590 loader. From foundational routine maintenance and fluid change intervals to complex hydraulic cylinder rebuilds, every chapter provides explicit diagnostic steps, factory-approved procedural workflows, and exact torque values to eliminate guesswork in the shop or field.

In-Depth Preventative Maintenance & Component Servicing

The Bobcat S590 Skid-Steer Loader Service Manual provides rigorous maintenance guidelines structured by operating hours. Technicians have access to complete procedures for draining and replenishing fluids, including engine crankcase lubrication meeting API CI-4 or ACEA E7 ratings, chaincase lubricants, and hydraulic system fluids ranging from Bobcat All-Season to specialized biodegradable formulas. Fuel system upkeep is thoroughly explained, highlighting fuel priming routines, water separator draining, and specific precautions necessary when operating on ultra-low sulfur diesel or B5/B7 biodiesel blends.

Hardware variations across production changes are addressed directly. The manual distinguishes between earlier cooling configurations with square expansion tanks and later configurations featuring rectangular tanks, detailing specific condenser unlatching and swing-out radiator access methods for thorough cleaning. Crucial daily safety systems—such as the Bobcat Interlock Control System (BICS), lift arm bypass valve, operator cab door sensors, and seat belt retractors—include full operational checkouts and adjustment criteria.

IMAGES PREVIEW

Hydraulic Diagnostics & Component Rebuilding

Hydraulic performance is vital on the Bobcat S590 Skid-Steer Loader, and this service manual provides deep technical instructions for isolating and correcting pressure loss or cycle-time faults. Step-by-step diagnostic workflows show how to isolate lift and tilt cylinders using pressure plugs to distinguish between internal piston seal blow-by and main spool leakage. Technicians are provided with complete tear-down and assembly specifications, such as torquing the lift cylinder piston retaining nut to 1152 N·m (850 ft-lb) or 780 N·m (575 ft-lb) on updated designs, tightening cylinder head glands to 373 N·m (275 ft-lb) or 550 N·m (405 ft-lb), and using specialized expander and compressor tools for seal installation without distortion.

Main system pressure calibration is clearly documented. Mechanics can verify primary relief valve cracking pressures at the front quick couplers using an in-line flow and pressure tester, adjusting the valve to factory specifications between 23787 and 24476 kPa (3450 to 3550 psi), or 24100 kPa (3500 psi) on B5N4 units. Accompanied by full hydraulic and hydrostatic schematics covering standard mechanical foot controls, advanced Selectable Joystick Controls (SJC), high-flow auxiliary circuits, and power attachment options, this manual serves as an indispensable shop guide.

Professional Shop Diagnostic Utility and Immediate Access

Utilizing the authentic Bobcat S590 Skid-Steer Loader Service Manual gives owner-operators, independent repair facilities, and equipment fleet managers the technical confidence to carry out repairs efficiently and accurately. Adhering to verified manufacturer assembly steps, bolt torque ratings, and system test parameters protects valuable machinery, prevents collateral hydraulic component failure, and ensures machine compliance with original factory performance benchmarks.

This service manual is delivered as an instant digital PDF download immediately upon completed order. You gain instant access with zero shipping wait times, allowing you to load the entire document onto shop laptops, field tablets, or mobile devices right at the machine. The PDF format allows you to navigate effortlessly through service chapters, zoom in on high-resolution hydraulic schematics, or print out clean mechanical procedure pages directly for bench work.
