JCB 712, 716 Common Problems This Manual Covers
JCB 712 articulated hauler severe leak and unsafe high-pressure spray at quick-release couplings. p. 272
Inspect the sealing faces and B.S.P adapters. Torque the adapters to either 20 Nm (15 lbf ft) or 102 Nm (75 lbf ft) as specified on page 272. Replace damaged O-rings immediately. Refill the tank to its 82.0 Litres capacity before testing the tipping circuit.
Manual Section: HydraulicsArticulated hauler transmission slipping under heavy load and high torque converter stall speed. p. 169
Test the pump flow and measure clutch pressure. Verify the maximum clutch leakage rate does not exceed 4.5 litres (1 UK gal; 1.2 US gal) per min as outlined on page 169. Replace worn converter seals if leakage is excessive. Drain and refill the 18.0 Litres transmission oil.
Manual Section: Transmission FaultfindingSoft brake pedal feel and machine pulling to one side during hard braking. p. 251
Adjust the foot pedal linkage and test the flow regulator. Check the brake system adjustment on page 251 to ensure the maximum brake pressure differential stays below 30 bar (435 lbf/in2). Bleed the lines to remove trapped air and retest parking brake holding pressure.
Manual Section: Brake System AdjustmentEngine turns over slowly or refuses to crank during cold weather start attempts. p. 297
Trace the starter relay circuit using the wiring diagram on page 297. Test the battery to confirm it delivers the required 410 cold crank amps listed on page 280. Inspect the armature windings for continuity and check the solenoid unit for burnt contacts or open circuits.

Document Quality
This document is a scanned PDF with an OCR text layer, allowing you to search and copy text throughout. The text quality is generally clear and readable, though some original scanned pages exhibit slight blurriness or fading. Diagrams and illustrations are primarily raster images or photos, with most labels being readable, but some older images lack sharpness upon closer inspection.
