JCB FASTRAC 125, 135, 155, 185 Common Problems This Manual Covers
JCB FASTRAC 125 transmission range selection fails to engage and diagnostic LED stays illuminated p. 136
Inspect the air switches and magnetic switches at the rear of the cab. Check the Selectronic range change solenoids fuse on page 136 and replace if blown with a 10 Amp fuse. Verify the hydraulic fluid level to ensure the system maintains its 75 Litres (16.5 UK Gal) capacity.
Manual Section: MaintenanceAnti-lock brake system warning lamp remains continuously illuminated on the dashboard while driving p. 34
Test the tractor and monitor the dashboard indicators. Verify if the ABS fault warning lamp stays on at speeds above 10 km/h (6 mph) as noted on page 34. Check the brake fluid level and confirm the front and rear reservoirs hold their 0.75 Litres (0.17 UK Gal) capacity.
Manual Section: OperationEngine cranks very slowly or completely fails to start during cold morning operation p. 138
Inspect the battery terminals for corrosion and clean them thoroughly. Remove the caps and verify the battery electrolyte level is 6 mm (0.25 in) above the plates as shown on page 138. Test the clutch depressed start circuit fuse and replace with a 10 Amp fuse if necessary.
Manual Section: MaintenanceAir brake system takes too long to build pressure and the compressor squeals p. 141
Inspect the air compressor drive belt for glazing or heavy wear. Adjust the compressor belt tension to exactly 10 mm (0.4 in) of slack as directed on page 141. Drain the air system tanks to remove accumulated moisture and check the lines for visible air leaks.
