John Deere 318E Troubleshooting
The
John Deere 318E skid steer loader is powered by 202.5 cu.in (3.3L) Yanmar
4TNV98C 4-cylinder direct injection liquid-cooled diesel engine with a rated
power of 60 hp (44.8 kW). The John Deere 318E is equipped with a single-speed or
two-speed hydrostatic transmission, vertical-lift loader boom, 80HD drive
chains, and 10.00x16.5 standard tires. The hydraulic system has a pump with
fluid flow rate of 18 gpm (68.2 lpm) or 25 gpm (94.5 lpm). The skid steer loader
has a rated operating capacity of 1950 lbs (885 kg) and tipping load of 3900 lbs
(1770 kg). The boom breakout force is 3500 lbs (1590 kg), and bucket breakout
force is 6000 lbs (2725 kg).
