JCB 3C 1400B & variants Common Problems This Manual Covers
JCB 3C 1400B engine cranks poorly or turns over slowly during cold weather startup attempts. p. 46
Inspect the battery electrolyte levels as outlined on page 46. Perform this check every 1600 hours. Clean the terminals and verify the negative ground connection is secure. Check the engine fan belt slack on page 36, ensuring it measures exactly 10 mm (0.4 in.) to maintain proper alternator charging.
Manual Section: Battery Electrolyte & Terminal MaintenanceMachine starts up normally but will not move forward or backward when engaged in gear. p. 40
Verify the transmission oil pressure warning light extinguishes after starting, shown on the instrument panel on page 12. Drain the JCB Syncro Shuttle oil and clean the strainer screen on page 40. Perform this maintenance every 800 hours on machines from serial number 320000 to prevent valve sticking.
Manual Section: Gearbox-Oil LevelHydraulic boom and bucket functions operate slowly accompanied by a loud system whining noise. p. 56
Inspect all lines for chafing or kinks before checking fluid levels. Verify the hydraulic system capacity on page 56 matches the required 33.6 US Gal. Replace the hydraulic filter element every 400 hours as shown on page 44 to ensure unrestricted fluid flow to the main pump.
Manual Section: Knuckle BoomParking brake fails to hold the machine stationary when parked on a steep incline. p. 42
Check the brake pads and cable slack on page 42. Adjust the tension until the lever engages firmly. Renew the brake pads immediately if the friction material thickness measures less than 3mm (0.125in) to maintain safe holding power during operation.
