Case 1838 Troubleshooting
The
Case 1838 skid steer loader driveline system components: a 134 cu.in (2.2L)
Kubota V2203-DI-B 4-cycle 4-cylinder direct injection naturally aspirated
water-cooled diesel engine with a rated power of 46 hp (34 kW), and single-speed
hydrostatic transmission. The hydraulic system has a pump with a rated capacity
of 15.8 gal/min (59.8 l/min). The Case 1838 is equipped with a radial-lift
loader boom, 80HT drive chain, and 10.00x16.5 or 7.50x15 tires. The loader has a
boom breakout force of 2775 lbs (1260 kg) and bucket breakout force of 3065 lbs
(1395 kg). The rated operating capacity is 1325 lbs (600 kg), and tipping load
is 2650 lbs (1200 kg).
