Kawasaki MULE 4010 TRANS4x4 Diesel UTV Service Manual – 2008 (P/N 99924-1409-04)

Kawasaki’s MULE 4010 TRANS4x4 Diesel service manual, Fourth Edition dated March 14, 2011, P/N 99924-1409-04, covers the KAF950G9, KAF950GA, KAF950HA, KAF950GB, and KAF950GC utility vehicles.

Searchable Text, Bookmarks, and Wiring Detail

Text and diagram access: Body text is searchable, with embedded bookmarks for chapters and individual procedures. Some diagram labels are outside the searchable text layer. Dense wiring diagrams require zooming to read small wire codes.

One printable, 533-page PDF, including the original cover and front matter, 12 blank pages, and the final model-application sheet.

Diesel Engine, Drivetrain, and EPS Service

The following selected service topics summarize the manual’s coverage. Other included work ranges from cargo-bed latch adjustment to cable, wire, and hose routing.

• Engine repair: Engine removal and installation, cylinder-head service, valve-seat repair, timing-gear work, and crankshaft, piston, and crankcase inspection.

• Diesel injection: Pump removal and installation, injection-timing inspection and adjustment, nozzle pressure and spray-pattern testing, and fuel-system troubleshooting charts.

• Converter and transmission: Drive-belt deflection adjustment, drive and driven pulley service, transmission case assembly, and high/low and 2WD/4WD shift mechanisms.

• Final drive: Front final gear case overhaul, limited-slip differential clutch inspection, bearing preload, bevel-gear backlash, and tooth-contact adjustment.

• Brakes and suspension: Brake-line bleeding, master- and wheel-cylinder service, MacPherson strut work, and De Dion rear axle suspension components.

• Electric Power Steering: Self-diagnosis, service-code reading and erasing, neutral-position registration, circuit checks, and EPS unit replacement.

• Electrical testing: Battery evaluation, alternator and starter-motor inspection, glow-plug and preheating-system checks, and model-specific wiring diagrams.

Written primarily for trained mechanics in a properly equipped shop, the manual also supports owners performing basic maintenance and repair who understand mechanical fundamentals, tool use, and workshop procedures; work beyond their experience belongs with qualified mechanics.

Engine Repair and Scheduled Maintenance

The system chapters keep maintenance, diagnosis, and rebuild references together for bench use. Periodic maintenance charts cover valve-clearance inspections, fuel-filter service, and transmission-oil changes.

Step-by-step procedures extend to rocker-arm disassembly, valve-guide replacement, cylinder boring and honing, and bearing-clearance inspection. Standard dimensions and service limits support decisions about component reuse and machining. The valve-seat section warns that excessive cutting can sink a valve far enough to require cylinder-head replacement.

Denso VE Injection Testing and Timing

The fuel chapter distinguishes nozzle markings when specifying injection pressure and pump plunger stroke. Timing inspection uses Dial Gauge Adapter 57001-1430, while nozzle checks address opening pressure, leakage, buzzing, and spray pattern.

Troubleshooting charts address injection-pump complaints, but internal pump and nozzle disassembly is excluded from field service. Malfunctioning assemblies are replaced or referred to an injection specialist.

Converter Alignment and Final-Drive Setup

Engine installation includes converter alignment using Assembly Jig 57001-1566. The converter chapter distinguishes early and late air-cleaner arrangements, including changes within the KAF950GA/HA configurations.

Transmission coverage extends into shift cables, differential gears, bearings, oil seals, and sectional illustrations. Front final-drive instructions explain shim selection and factory-matched ring-and-pinion replacement. Incorrect bearing preload or tooth contact can damage the bearings and gears.

Brake and Suspension Adjustments

Beyond hydraulic service, the chassis chapters include drum and lining wear checks, parking-brake adjustment, leaf-spring removal, and rear shock-preload adjustment for load and terrain.

Mechanical work requires proper shop safety precautions, particularly when supporting the vehicle or testing the high-pressure diesel injection system.

EPS Codes and Electrical Fault Tracing

Code 31: The service-code table links this warning specifically to a replacement EPS ECU whose neutral position has not been registered. Steering-gear, universal-joint, knuckle, and related mounting work also has registration requirements.

The EPS System Diagnosis Flow Chart and EPS Neutral Position Registration Flow Chart support diagnosis and post-repair setup. Circuit and power-supply checks help distinguish wiring faults from components requiring replacement. EPS unit service covers diagnosis and replacement; internal disassembly is prohibited.

Separate wiring diagrams distinguish KAF950G9/GA/HA from KAF950GB/GC configurations. Battery Testing Charts accompany charging checks, with additional circuit references for starting, preheating, and radiator-fan operation.

Cooling and Lubrication References

Water-pump inspection, radiator-cap testing, thermostat checks, and coolant replacement are covered alongside component removal and installation. The lubrication chapter provides an Engine Oil Flow Chart, oil-pressure testing, and oil-pump and relief-valve inspection.

A Preview of Idle, Injector, and Coolant Specifications

The idle-speed inspection specifies a thoroughly warmed engine, with a standard range of 850–950 r/min.

Injector opening-pressure specifications differ by nozzle marking: 13,239–14,220 kPa for red- or green-marked nozzles, and 14,465–14,955 kPa for unmarked nozzles.

The coolant-change section lists a total coolant amount of 4.4 L, alongside mixture information and filling instructions.
