Workshop Repair and Diagnostic Scope
This Bobcat S175 service manual goes well beyond routine maintenance. The hydraulic section covers the lift, tilt and Bob-Tach cylinders, main relief valve, standard and ACS/SJC control valves, hydraulic pump variants, filters, reservoir, oil cooler, auxiliary circuits and high-flow components. Hydraulic and hydrostatic schematic sets are provided for standard machines and configurations with 2-speed, high-flow and SJC options. Troubleshooting charts help trace symptoms such as slow or uneven hydraulic action, lift-arm drift and pressure-related faults before component repair is undertaken.
The hydrostatic and drive material follows the power path through hydrostatic pumps and drive motors, charge pressure, drive belt, two-speed valve, brakes, chaincase, axles and related drive components. The manual includes removal and installation procedures, component inspection, parts identification, disassembly and assembly steps, pressure checks and adjustment information where applicable. This makes the 2013 Bobcat S175 Skid-Steer Loader Service Manual 6987035 – S/N A3L520001 & Above useful for both fault isolation and major mechanical work.
Electrical coverage includes harness and connector identification, fuse and relay locations, solenoid tests, battery, alternator and starter service, instrument panels, Bobcat controllers, speed sensors, diagnostic service codes and the Bobcat Interlock Control System (BICS™). Separate material addresses ACS and SJC control systems, electrical/hydraulic controls, Service PC connections, calibration routines, steering drift compensation, control-panel setup, password functions, the maintenance clock and back-up alarm troubleshooting. These sections provide a structured path from a displayed service code or control-system symptom to testing and repair.
Engine service is centered on the Kubota V2403-M-DI family used in this loader; the specification section identifies the engine as Kubota V2403-M-DI-E3B Interim Tier IV. Coverage includes engine specifications and torque values, troubleshooting, engine removal and installation, compression checking, cooling and lubrication systems, fuel injection equipment, cylinder head work, valve servicing, crankshaft and pistons, camshaft and timing gears, and flywheel and housing service. The specification pages also give performance figures, capacities, electrical data, hydraulic data, dimensions, general bolt torques, hydraulic connection tightening information and hydraulic/hydrostatic fluid requirements.

Taken as a whole, the chapters connect scheduled maintenance with deeper diagnosis and component-level repair. A mechanic can move from symptom checks and service codes to pressure tests, wiring or hydraulic schematics, component removal, teardown and reassembly, then verify settings against the manual’s torque, capacity and specification data. The manual also distinguishes option-dependent procedures such as Standard Controls, ACS, SJC, High Flow and 2-Speed configurations where the service method or component layout changes.
Machine Specifications and Service Data
The specification section identifies a four-cylinder, liquid-cooled Kubota V2403-M-DI-E3B Interim Tier IV diesel engine with 2,433 L (148.5 in3) displacement. It lists rated output, torque, bore and stroke, idle ranges, hydrostatic four-wheel drive details, travel speeds, operating capacity, operating weight and breakout forces. Hydraulic data includes standard and high-flow pump capacities, quick-coupler relief pressure, cylinder dimensions and hydraulic function times. Electrical information covers the 12-volt system, 90-amp alternator, battery and starter, while capacity tables cover the fuel tank, engine oil, cooling system, hydraulic / hydrostatic reservoir and system, and chaincase reservoir.
For repair work, the manual supplies many job-specific torque values alongside general SAE and metric bolt torque charts. Hydraulic connection tables cover O-ring face seal, flare and port-seal fittings, and the hydraulic / hydrostatic fluid section provides viscosity guidance for operating temperature ranges. This combination is especially valuable when a repair involves both mechanical disassembly and system setup, because the same manual can be used to confirm the correct tightening value, fluid requirement, pressure range or adjustment before the loader is returned to service.
Get the S175 Back to Work
The 2013 Bobcat S175 Skid-Steer Loader Service Manual 6987035 – S/N A3L520001 & Above supports routine servicing, hydraulic and hydrostatic diagnosis, electrical troubleshooting, BICS™ checks, engine repair, drive-system work, control calibration and major component overhaul on the covered S175 loader. Using the documented procedures, test information, schematics, torque values and specifications helps reduce guesswork and gives each repair a clear reference point. Your manual is delivered instantly as a PDF after payment, with no shipping to wait for; open it on a computer, tablet or phone, and print the pages you need for the workshop.
