John Deere Agriculture 6100–6600 SE Series Common Problems This Manual Covers
John Deere 6400 hydraulic pump grinding noise, implements slow to raise or won't lift at all p. 1210
Check hydraulic fluid level and filter condition before pulling the pump. Connect a pressure gauge at the test port; system maximum is 20000 kPa (200 bar; 2900 psi) per page 33. If pressure reads low, inspect the charge pump for wear and clean the suction strainer. Replace the filter if it shows contamination.
Manual Section: Hydraulic SystemEngine won't start or turns over slowly in cold weather below freezing p. 137
Verify battery terminals are clean and tight. Check that engine slow idle is set to 800-900 rpm per page 29. If the engine cranks but won't fire, bleed the fuel system; air trapped in the injector lines after a cold soak is the most common culprit. Fuel system procedures begin on page 137.
Manual Section: Fuel, Air Intake, Cooling and Exhaust SystemsSyncroPlus transmission slipping out of gear or won't shift cleanly under load p. 303
Check transmission oil level first; low fluid causes slip before any mechanical damage appears. Verify the shift linkage adjustment if fluid is clean and at level. SyncroPlus 30 km/h units hold 64 L (16.9 US.gal.) on initial fill; a short fill starves the clutch packs under load. Shift control procedures are detailed starting on page 303.
Manual Section: SyncroPlus TransmissionCab air conditioning blowing warm air, compressor cycling on and off every few seconds p. 1617
Test for refrigerant loss first; a compressor cycling rapidly is the classic sign of low charge. On 6100, 6200, 6300, 6400, 6506, and 6600 models, the system holds 1300 g (2.86 lb) of refrigerant per page 1617. Leak-test the system with a detector, then evacuate and recharge to spec before returning to service.
Manual Section: Operator's Cab and 4-Post Roll GuardRear wheels loose or wobble felt through the seat at field speeds p. 773
Torque the rear wheel mounting bolts before anything else. On flanged axle configurations, spec is 500 N·m (370 lb-ft) per page 779. Check for worn or missing hub spacers after re-torquing. If wobble persists with bolts at spec, inspect the final drive housing for bearing wear and cracked axle flanges.
Manual Section: Drive SystemsFrequently Asked Questions
What are the torque specs for John Deere 6000 series engine bolts?
For 6100-6400 Tractors and SE models, the engine support bracket to flywheel housing cap screws should be torqued to 95 N·m (70 lb-ft). Engine mountings cap screws for these models require a torque of 100 N·m (74 lb-ft). For 6506 and 6600 Tractors, the engine to main frame cap screws should be tightened to 100 N·m (74 lb-ft).
