JCB Robot 160 & variants Common Problems This Manual Covers
JCB Robot 160 complete loss of hydraulic power and drive mobility after sudden loud clunk p. 267
Inspect the hydraulic pump drive coupling for sheared bolts. Replace damaged drive plate A bolts and torque them to 23 Nm (17 lbf ft, 2.3 kgf m) as shown on page 267. Secure coupling B capscrew D to 49 Nm (36 lbf ft, 5 kgf m).
Manual Section: Hydrostatic Transmission Fault FindingInability to actuate auxiliary hydraulics or poor oil flow control at the right-hand controller p. 13
Check the hydraulic supply pipes and fittings for severe leaks or blockages. Replace faulty lines and tighten 1/4 inch BSP adaptors to exactly 18.0 Nm (13.0 lbf ft) according to the specifications on page 13. Verify full system pressure before testing attachments.
Manual Section: High-flow Circuit Fault FindingEngine overheating with erratic hydraulic performance and excessive noise from the loader pump p. 67
Drain the entire hydraulic system and flush the reservoir. Refill the tank with fresh fluid to the 30 Litres (6.6 Gal) capacity limit specified on page 67. Inspect the filter for metal shavings larger than 40 microns (0.00157 in) to rule out internal pump failure.
Manual Section: Loader Circuit Fault FindingFrequently Asked Questions
What do the fault codes mean on a JCB Robot 160/170/180?
The manual lists blink codes for the Power Management System (PMS) warning light G. Blink Code 1 indicates a signal from alternator W terminal is absent or incorrect. Blink Code 2 means the sensitivity control F is not working (if fitted). Blink Code 3 signifies a dump valve solenoid short circuit, and Blink Code 4 indicates a dump valve solenoid open circuit.
What are the torque specs for JCB Robot 160/170/180 wheel nuts, track/boom pins, and hydraulic fittings?
Road wheel retaining nuts should be tightened to 220 Nm (162 lbf ft; 22.5 kgf m). For hydraulic connections, BSP adaptors range from 18.0 Nm (1.8 kgf m, 13.0 lbf ft) for 1/4 inch to 206.0 Nm (21.0 kgf m, 152.0 lbf ft) for 1 1/4 inch. SAE connections vary from 20.0 - 28.0 Nm (2.0 - 2.8 kgf m, 16.5 - 18.5 lbf ft) for size 4 to 280.0 - 380.0 Nm (28.5 - 38.7 kgf m, 210.0 - 280.0 lbf ft) for size 20. Track frame mounting bolts should be tightened to 184 Nm (136 lbf ft, 18.8 kgf m).
What are the replacement specifications for Hydraulic pump drive coupling?
When replacing the hydraulic pump drive coupling, ensure the drive plate is fitted with the flat face against the flywheel and boss facing outwards. Coat threads of bolts C with JCB Threadlocker and Sealer, tightening to 23 Nm (17 lbf ft, 2.3 kgf m). For capscrew D, use JCB Retainer (High Strength) and torque tighten to 49 Nm (36 lbf ft, 5 kgf m).
How do you fix JCB Robot 160 complete loss of hydraulic power and drive mobility after sudden loud clunk?
