Ford 555 Backhoe Loader

The Ford 555 is a two-wheel drive backhoe loader. This model was manufactured from 1978 to 1984. The Ford 555 is powered by 201 cubic inches three-cylinder liquid-cooled diesel engine with a rated power of 62 hp (46.2 kilowatt) and 217 Hm (160 lb-ft) of max torque at 1200 rev/min.

The Ford 555 is equipped with two transmission options: 4x4 transmission with a torque converter, or 6x4 unsynchronized gear transmission with a manual reverse. Max. travel speed (forward and reverse): 20.2 mph (32.5 kph). The open center hydraulic system includes a gear pump with rated capacity of 27 gal/min (102.3 l/min). The main relief pressure is 148 bar (2150 psi).

The Ford 555 is equipped with 7.50x16 or 9.00x16 front tyres and 16.9x24 or 16.9x28 rear tyres. The front end loader has a max lift height of 129" (3270 mm) at pin, and bucket dump clearance of 105" (2660 mm). The lift capacity is 4700 lbs (2130 kg) to a max height at pin, and boom breakout force is 9800 lbs (4445 kg). The rated cycle times are 4.7 seconds raising to maximum height, and 1.6 seconds maximum bucket dumping. The 84" standard material bucket has a nominal heaped capacity of 1.0 cu.yd (0.80 m3).

The backhoe can dig to a maximum depth of 185" (4690 mm). The bucket cylinder has a digging force of 9735 lbs (4415 kg), and crowd cylinder has a digging force of 6920 lbs (3140 kg). The overall reach from swing pivot is 231" (5860 mm) at ground line. The backhoe can be fitted with 12", 18", 24", and 36" buckets.
