JCB JS140, JS205, JS215 Common Problems This Manual Covers
JCB JS140 engine will not start or stops unexpectedly during morning startup sequence p. 219
Inspect the battery isolator switch and check the system voltage. Review the fuel system and starter switch wiring for faults using the diagnostic steps on page 219. Recharge or replace the battery if it is completely discharged before attempting another start.
Manual Section: Fault-FindingEngine overheating and reduced machine output under heavy load during afternoon shifts p. 220
Check the coolant reservoir and refill if low, noting the JS140 cooling system capacity is 19.7L. Inspect the radiator for dirt buildup and verify the fan belt is tight. Test the water temperature sensor and thermostat using page 220 if the temperature gauge remains high.
Manual Section: Fault-FindingHydraulic attachment performance drops significantly during continuous rock breaker or crusher use p. 143
Replace the breaker in-line filter, which has a strict 100h replacement interval documented on page 143. Verify the hydraulic oil level in the sight glass. Check the hydraulic flow rate is within the specification for your attachment to prevent slowdown.
Manual Section: MaintenanceWeak or erratic hydraulic performance and sluggish boom movement during normal operation p. 143
Replace the hydraulic oil return filter at the 500h interval specified on page 143. Drain the tank and refill with fresh fluid if the oil viscosity is excessively high. Verify the lower track rollers are torqued to 288 N·m if you hear undercarriage noise.
Manual Section: MaintenanceFrequently Asked Questions
What is the torque spec for JCB JS140 slew ring bolts?
For the JCB JS140, the tightening torque for the turntable bearing (undercarriage) bolts is 259 N·m, and for the turntable bearing (revolving frame) bolts, it is also 259 N·m. Both use M16 bolt diameters and require a 24 mm wrench.
What are the replacement specifications for Hydraulic oil return filter?
For crusher, cutter, or pulveriser use, the hydraulic oil return filter (1) must be changed whenever the period of breaker/crusher/pulveriser use exceeds 100 hours, regardless of the total machine operating hours. For general use, the hydraulic return filter (inside tank) has a change period of 500 hours.
What are the replacement specifications for Suction filter?
For crusher, cutter, or pulveriser use, the suction filter (1) must be changed whenever the period of breaker/crusher/pulveriser use exceeds 100 hours, regardless of the total machine operating hours. For general use, the suction strainer has a change period of 2,000 hours.
How do you fix JCB JS140 engine will not start or stops unexpectedly during morning startup sequence?
Inspect the battery isolator switch and check the system voltage using the diagnostic steps on page 219. Recharge or replace the battery if it is completely discharged before attempting another start.
