Kawasaki MULE 2510 Diesel UTV Service Manual, 1999 (P/N 99924-1251-01)

The Kawasaki MULE 2510 Diesel / KAF950-A1 Service Manual, P/N 99924-1251-01, is the first edition dated October 14, 1999. It provides factory maintenance, troubleshooting, and repair information for this utility vehicle.

PDF Search Limits and Wiring Detail

Search, navigation, and small labels: PDF text search and embedded bookmarks are not available. The smallest wire-color codes and connector labels on the two-page vehicle wiring diagram require zooming.

Supplied as one 334-page printable PDF, with 17 chapters and the covers, front matter, and two-page errata sheet included in that total.

Diesel Injection, Drivetrain, and Chassis Repairs

These content highlights are a selection from the manual; other topics include air-cleaner service and spark-arrester cleaning.

• Fuel injection: Pump and injection-pipe removal and installation, dial-gauge timing inspection and adjustment, plus nozzle pressure, leakage, and spray-pattern tests.

• Engine repair: Engine removal, cylinder-head and valve-seat work, timing gears, crankshaft bearings, pistons, and cylinder boring and honing.

• Cooling system: Pressure testing, coolant filling and air bleeding, water-pump inspection, and service procedures for the radiators, thermostat, and pressure-relief cap.

• Converter and transmission: Belt replacement, drive and driven pulley disassembly, case splitting, and Hi/Low, 2WD/4WD, and differential shift-mechanism service.

• Final drive: Limited-slip differential clutch inspection, pinion-bearing preload, bevel-gear backlash and tooth-contact adjustment, propeller shafts, axles, and joint-boot replacement.

• Brakes and chassis: Hydraulic drum-brake repair, master-cylinder service, wheel-cylinder inspection, brake bleeding, struts, leaf springs, rack-and-pinion steering, and wheel alignment.

• Electrical diagnosis: Alternator and starter repair, glow plugs, preheating timer and relay tests, fuel cut solenoid inspection, radiator fans, and warning-light switches.

Written primarily for trained mechanics in a properly equipped shop, this manual also supports owners doing basic maintenance and repair who understand mechanics, tools, and workshop procedures.

Injection Timing and Diesel Fault Finding

The Denso VE pump section documents idle and maximum-speed adjustment, fuel-filter water draining, and fuel-filter bleeding. The Hard Starting flowchart connects fuel delivery with preheating, glow-plug condition, injection timing, and the fuel cut solenoid, helping separate electrical faults from fuel-system problems.

Related charts address unstable idling, stalling, lack of power, excessive smoke, and an engine that will not stop. Timing work calls for Dial Gauge Adapter 57001-1430.

Internal pump and nozzle work: These units are not covered by bench-overhaul instructions. Kawasaki calls for replacement or specialist repair, such as through a Denso Service Station.

Diesel injection testing involves high pressures and specialized equipment. Follow the workshop documentation and use personnel trained for these tests.

Internal Engine Work, Lubrication, and Cooling

Cylinder-head tightening sequences, rocker-arm and valve-guide inspection, and valve-clearance adjustment support top-end service. Step-by-step procedures extend to crankshaft removal and installation, with oversize-piston and undersize-bearing repair data. Compression testing specifies Compression Gauge Adapter 57001-1431.

The Engine Oil Flow Chart accompanies oil-pressure measurement and oil-pump and relief-valve inspection. Component-specific torque tables, fluid capacities, wear limits, clearances, and electrical test values accompany the relevant systems; scheduled work is listed in the Periodic Maintenance Chart.

The cooling-system Flow Chart maps the front and rear radiators and thermostat bypass. Separate checks address radiator fans and the pressure-relief cap.

Pulley Alignment and Gearbox Service

The Transmission Sectional Figure supports internal shaft and gear work. Rear differential-lock service is distinct from the front limited-slip unit, whose adjustment sections include shim tables and drive/coast tooth-contact illustrations.

Propeller-shaft installation includes yoke alignment. Engine mounting alignment uses Assembly Jig 57001-1365 to position the engine for the converter drive.

The pulley instructions warn that placing the clutch holder on the spider assembly can break that assembly.

Drum Brakes, Suspension, and Steering

Step-by-step drum removal and installation procedures address the press-fit mounting and dedicated puller and pusher tools. Suspension detail includes strut spring replacement and rear shock preload adjustment; steering procedures cover rack-guide preload and toe-in adjustment.

Wiring References and Included Errata

The Preheating System Circuit accompanies glow-plug control tests. The vehicle Wiring Diagram identifies European-model horn and reverse-light details, while cable, wire, and hose routing drawings show installation paths.

Errata 99929-1364-01 correct breather-hose routing, new drive-belt orientation, oil-filling precautions, and rear shock mounting details. The oil-filling caution explains how filling too quickly can send oil through the breather into the intake, causing hydraulic lock and severe engine damage.

Examples of Valve Clearance and Belt Wear Limits

The valve section specifies 0.2 mm clearance with the engine cold, linking its adjustment instructions to a defined inspection condition.

Drive-belt inspection lists a standard width of 31.2 mm and a service limit of 29.7 mm. The accompanying inspection also addresses cracks, breakage, peeling, and pulley condition.
