JCB 403 WHEEL LOADER

Technical Description

The JCB 403 Wheel Loader is a compact, versatile machine powered by a 36 hp Kubota V1505 engine, naturally aspirated, delivering Stage 3A emissions compliance. It features a four-cylinder, four-valve engine with a displacement of 91.5 cu in, producing maximum power at 2700 rpm and peak torque of 91.6 Nm at 2200 rpm. The machine incorporates a ZF/Bosch-Rexroth transmission offering forward and reverse speeds up to 18.7 mph, with a two-speed hydrostatic system for precise control. Its hydraulic system delivers 180 bar pressure through a 10.7 gal/min gear pump, enabling a bucket breakout force of 3597 lbs and fast cycle times (raise: 4.4 sec, dump: 2.7 sec, lower: 3 sec). The wheel loader’s operating weight is approximately 5527 lbs, with a fuel capacity of 12.7 gallons and hydraulic fluid capacity of 10.6 gallons. Dimensionally, it is optimized for tight environments with a length of 13.7 ft, width over tires of 4.7 ft, wheelbase of 5.3 ft, and a cab height of 7.3 ft. Max hinge pin lift height reaches 9.5 ft, providing a dump clearance of 7.1 ft, with a reach of 1.2 ft at maximum lift and dump. It features robust ZF axles with 0.9 gal front and 1.1 gal rear axle oil capacity. The electrical system runs on 12 V, supported by a 72 Ah battery and 60 Ah alternator. The 403 offers options like differential locks front and rear, an oscillating center joint for terrain adaptability, and a high-strength chassis with patented parallel lifting arms for durability and operator comfort. Safety features include ROPS/FOPS certified cab variants and electronic quick-hitch isolation systems for secure attachment handling. This compact loader balances power, agility, and reliability for demanding material handling tasks in confined spaces.
