Machine, Engine and Service Data

The manual identifies a John Deere diesel engine for each loader: model 3029D for the 240 and 3029T for the 250. Both are three-cylinder 2.9 L engines with a 106 mm (4.17 in.) bore, 110 mm (4.33 in.) stroke, 17.8:1 compression ratio, and a rated speed of 2400 rpm. The specifications distinguish the 240 by serial-number break for rated output: 34.3 kW (46 hp) through S.N. 240852 and 38 kW (51 hp) from S.N. 240853, while the 250 is listed at 45.5 kW (61 hp).

Machine data goes beyond the engine. The specification section provides fluid capacities, hydraulic and hydrostatic data, dimensions, operating weights, rated operating capacities, ground speeds, tire sizes, recommended lubricants, fastener torque charts, O-ring and face-seal fitting service data, diesel fuel information, coolant requirements, and serial-number locations. Examples include a 56.7 L (15 gal) fuel tank, 23 L (6 gal) hydraulic system, 9.5 L (10 qt) cooling system, and 6.5 L (6.9 qt) engine-oil capacity with filter. Standard hydraulic/charge pump flow is listed separately for each loader, with optional high-flow values also provided.

Taken together, these chapters make the John Deere 240 250 Skid Steer Technical Manual TM1747 a broad machine-service reference rather than a single-system booklet. The technician can move from specifications and component identification into operating theory, fault isolation, measured tests and adjustments, and then the applicable removal, inspection, repair or installation procedure. Electrical coverage is especially extensive, with circuit schematics, wire-harness layouts, diagnostic sequences and test points, while the hydrostatic and hydraulic sections combine schematics with pressure and flow testing and detailed component service.

Important Engine Repair Reference

The diesel-engine section includes machine-specific diagnosis, testing, adjustments, engine removal and installation, and radiator service, but it directs internal engine repair to CTM125. Starter and alternator repair is directed to CTM77. This distinction is useful when choosing the manual: TM1747 concentrates on the 240/250 skid steer installation, systems and machine service while referring certain component-level overhaul work to the separate component technical manuals.

IMAGES PREVIEW

Diagnostics, Schematics and Repair Procedures

For troubleshooting work, TM1747 provides more than symptom lists. The electrical section includes theory of operation and diagnosis for starting, preheat, charging, warning-light, gauge, lockout and park-brake circuits, along with a main schematic and harness-specific diagrams. The hydrostatic section provides a complete system schematic plus tests for high-pressure relief, wheel speed, pump flow and case-drain condition. The hydraulic section adds system schematics for HUSCO- and Sauer-Danfoss-equipped machines and test procedures for relief valves, pump pressure and flow, boom and bucket drift or load checks, and self-leveling adjustment.

Repair coverage follows those diagnostic sections with procedures for major machine components. The chaincase and axle chapter addresses drive-chain tension, axle-housing work and sprocket service. Hydrostatic repair covers pump and motor removal and installation as well as pump and motor disassembly, inspection and assembly. Steering procedures cover centering plates, controls, damper and cross-shaft components. Brake repair is divided by the serial-number configurations shown in the manual. Hydraulic repair extends through the charge pump, high-flow equipment, control valves, self-leveling valve, boom and bucket cylinders, and hydraulic Quik-Tatch components.

Use the Correct Data for 240 and 250 Service

The two machines share many systems, but the manual keeps model-specific values where they differ. The 240 is listed with a 681 kg (1500 lb) SAE rated operating capacity, while the 250 is listed at 794 kg (1750 lb). The manual also gives separate dimensions, hydraulic-flow values and tire sizes for the two models. Serial-number divisions appear in procedures where production changes affect components, including axle and brake service. Using the model and serial information together with the applicable procedure helps avoid treating every 240 or 250 configuration as mechanically identical.

Get the Technical Information Needed for the Job

The John Deere 240 250 Skid Steer Technical Manual TM1747 – 2003 PDF supports practical diagnosis, testing, adjustment and repair across the diesel-engine installation, electrical system, chaincase and axles, hydrostatic drive, steering, brakes, working hydraulics and cab-related equipment. It gives the technician the specifications, schematics, test points, pressure and flow checks, torque information, component locations and step-by-step service procedures needed to approach faults and repairs with the correct machine data instead of relying on general assumptions. The manual is supplied as an instant PDF download after payment, with no physical shipping required. It can be opened on compatible computers, tablets or phones and printed when a paper reference is useful at the machine or workbench.
