Need the factory test values for your 2004-2011 excavator? This 884-page JCB JS160 Service Manual PDF (OEM #9803/6570-7) covers the JS160, JS180, and JS190 models. Open to the hydraulics section for fluid routing schematics and system error codes. You get full wiring diagrams for the electrical harness, engine test values, and diagnostic charts for tracking down stubborn track motor faults. Confirm the main hydraulic pump displacement is pushing 63 cm3/rev on your JS180 before locking down the track guard bolts to 290 Nm. Guessing at relief valve pressures will only blow hoses and cost you downtime. Download this bookmarked file, pull up the right numbers on your shop tablet, and get back to turning wrenches.

JCB JS160 / JS180 / JS190 Common Problems This Manual Covers
JCB JS180 hydraulic functions weak and main pump fails to build sufficient pressure p. 175
Check the pump for internal oil leakage or air in the suction line as detailed on page 175. Verify the main relief valve is set to 314 bar. If the pump is worn, replace it, noting the 63 cm³/rev x2 displacement for this model.
Manual Section: Routine MaintenanceEngine runs rough with excessive valvetrain ticking noise when cold p. 836
Adjust the inlet and exhaust valve clearances. Set the inlet cold clearance to 0.15 mm (0.006 in) for JS160 and JS180 models as specified on page 836. For JS190 valve clearance, refer to page 836 for the correct specification.
Manual Section: EngineMachine loses power intermittently or fails to crank after routine maintenance p. 118
Inspect the battery connections for looseness or corrosion. Clean the terminals and retighten the battery bolts to the torque shown on page 118. Always isolate the battery before performing electrical service to prevent sudden arcs or component damage.
Manual Section: General InformationTrack frame components rattling or shifting during travel p. 120
Inspect the undercarriage for loose or missing fasteners. Torque the track guard bolts to 290 Nm (213 lbf ft) as specified on page 120. Replace any damaged hardware immediately. Proper fastener torque prevents further driveline misalignment or track motor damage.
Manual Section: Routine MaintenanceHydraulic system overheating and sluggish operation during heavy attachment use p. 85
Drain the hydraulic oil and inspect filters for contamination. When using a breaker for more than 75 percent of operation, replace the hydraulic return filter at the interval specified on page 85. Check the pump exit hose for interior degradation.
Manual Section: Routine MaintenanceFrequently Asked Questions
How do I reset the JCB JS160/JS180/JS190 error code?
To reset an error code, specifically the service indicator warning, access the 'SERVICE OFF' routine in the EMS SET+MODE (20 seconds) menu. You will be prompted to enter a four-digit dealer code using the 'Up/Down' keys and 'ACK' button. After entering the code and pressing 'SET', the service warning will be cancelled and recorded in the service history file.
What does the JCB JS160/JS180/JS190 fault code mean?
The manual provides tables listing various electrical fault text messages (error codes) displayed on the EMS, along with their descriptions. For example, code 101 'CRANK' means 'A crank signal was not detected by the ECU1', and code 102 'FUEL' means 'The fuel sensor is open-circuit'. These tables are found in the 'Electrical Fault Text Messages Displayed on the EMS' section.
How do I clear the service light on a JCB JS190?
To clear the service light (service warning LED) on a JCB JS190, access the 'SERVICE OFF' routine within the EMS SET+MODE (20 seconds) menu. You will need to enter a four-digit dealer code using the 'Up/Down' keys and 'ACK' button. Once the code is entered and 'SET' is pressed, the service indicator will be extinguished.
What are the torque specs for JCB JS160/JS180/JS190 track frame bolts?
For JCB JS160/JS180/JS190 models, the torque specification for 'Track Guard' bolts (M16 diameter, 24mm wrench) is 290 Nm (213 lbf ft) for tightening and 265 Nm (195 lbf ft) for checking. For 'Turntable Bearing (Slew Frame)' bolts (M16/M20 diameter, 24/30mm wrench), the tightening torque is 296/525 Nm (218/387 lbf ft) and checking torque is 275/470 Nm (203/347 lbf ft). Use JCB Threadlocker and sealer (High Strength) and tighten to the listed torque.
