Same 85-100 Common Problems This Manual Covers
Same Explorer 3 hydraulic lift slow or won't raise implement, gets worse as oil heats up
Check hydraulic oil level, then inspect the 25 micron suction filter screen; the clogging switch only trips at 0.4 to 0.5 bar restriction, so a partially blocked filter can hide. Tee a gauge into the lift circuit and confirm the 22.5 cc/rev gear pump builds its rated 190 bar; if pressure fades hot, overhaul the pump, procedures start on page 260.
Manual Section: Hydraulic System p. 260Steering wheel heavy to turn at low RPM, front wheels respond slowly
Verify steering circuit pressure against the 150 to 155 bar relief valve setting shown on page 68. Check for air leaks on the pump suction side and tighten any 37 degree seal fittings to 13 Nm on 7/16 inch lines. If pressure is low and no leaks appear, the 14 cc/rev steering pump is likely worn; replace it.
Manual Section: Technical Characteristics p. 68Clutch slips under load in higher gears, pedal engagement point sits near the floor
Split the tractor and measure the clutch plate; on the Explorer 3 85 the standard thickness is 8.5 mm, spec table on page 148. Replace any plate that is worn, glazed, or oil-soaked, and renew the thrust bearing while you are in there. Find and fix any rear seal leak before reassembly.
Manual Section: Transmission p. 148Transmission oil filter clogging warning light stays on after startup and will not clear
Check the alarm code reference starting on page 106 to confirm which switch is signaling. The clogging pressure switch calibration is 0.4 to 0.5 bar, listed on page 544; with cold thick oil the light can stay on briefly, that is normal. If it stays lit at operating temperature, replace the filter element and retest the switch.
Manual Section: Calibrations and Electronic Diagnosis p. 106Cab air conditioning blows warm air and the compressor cycles on and off rapidly
Test system pressures first; rapid compressor cycling usually means low charge from a slow leak. Recover the refrigerant, replace worn O-rings and the receiver drier, then pull a deep vacuum and recharge with exactly 1400 g, the quantity given on page 389. Leak-check every fitting with a detector before returning the tractor to work.
Manual Section: Hydraulic System Troubleshooting p. 389Front wheel screws work loose during transport, vibration and clicking over bumps
Torque front wheel screws to 350 Nm and rear wheel nuts to 500 Nm; the values are on pages 518 and 519. Clean mating faces of rust and paint before fitting the wheel, torque in a star pattern, and recheck after the first hour of loaded work. Replace any screw with stretched or damaged threads.
Manual Section: Wheels and Towing Hitches p. 518Frequently Asked Questions
What error codes indicate a coolant temperature sensor fault on the SAME Explorer 3 100?
Error code I18 indicates the coolant temperature sensor is short-circuiting to ground, while error code I19 indicates it is shorting to a positive feed. These codes are displayed on the instrument panel and can be verified using the All Round Tester (ART) displaying codes 18 and 19 respectively. p. 106
What is the correct tension for the fan drive belt on the SAME Explorer 3 85?
For a used belt, the deflection should be 10-15 mm when applying a load of 10 kg. For a new belt, the deflection should be 7-9 mm. Re-adjust the tension after approximately 50 operating hours. p. 127
What is the maximum operating pressure for the steering circuit pump?
The steering circuit gear pump has a maximum operating pressure of 155 bars and a displacement of 14 cc/rev. p. 66
What is the procedure for bleeding the air from the braking system?
To bleed the braking system, attach a transparent tube to the bleed valve and collect the fluid in a container. Fully depress the brake pedal until resistance is felt, hold it, then open the bleed screw to allow fluid and air to escape. Tighten the screw before releasing the pedal, and repeat until no air bubbles remain. p. 438
