John Deere 624H, TC62H Common Problems This Manual Covers
John Deere 624H engine cranks slowly and will not start in cold weather
Test battery state of charge and load test both batteries before winter hits. Clean and tighten cable connections at the battery and starting motor, using the Section 16 procedures starting on page 323. Review cold weather starting aids in Section 05 on page 221. If replacing the starter, support it properly; it weighs 30 kg.
Manual Section: Electrical System p. 323Loader boom drifts down and bucket responds slowly when working under full load
Check hydraulic oil level first; the reservoir and filters hold 117 L (31 gal). Inspect the loader control valve and boom cylinder seals using the procedures in Section 31, starting on page 515. Test pump flow before condemning cylinders, and replace the filters if the oil shows contamination or milkiness.
Manual Section: Loader p. 515Wheel wobble at travel speed and cap screws keep backing off after service
Torque all wheel cap screws to 675 N•m (500 lb-ft) in a star pattern, then recheck torque after the first few hours of operation. Follow the wheel removal and installation procedure on page 53, and inspect mounting faces and studs for damage, rust, or paint buildup before installing the wheel.
Manual Section: Powered Wheels and Fasteners p. 53Engine runs hot and coolant temperature gauge climbs during long grading passes
Check coolant level; the cooling system holds 22 L (23 qt). Clean chaff and debris from the radiator core and check fan belt tension. Pressure test the cap and hoses, then work through the cooling system procedures in Section 05, beginning on page 221, before replacing the thermostat or water pump.
Manual Section: Engine Auxiliary Systems p. 221Differential howls at road speed and axle oil leaks around the hubs
Drain the differential and inspect the oil for metal flake; refill capacity is 25 L (26.0 qt) per the spec on page 62. Use the exploded parts view to locate hub seals and bearings. Replace leaking seals in pairs and check bearing preload before final assembly.
Manual Section: Axles and Suspension Systems p. 62Frequently Asked Questions
What are the recommended service intervals for the service brakes?
