John Deere 110 Common Problems This Manual Covers
John Deere 110 TLB hydraulic functions fade after use with loud pump noise and no cylinder response.
Inspect the hydraulic suction hose and manifold for deterioration causing pump aeration. Drain the system and replace any damaged hoses. When reinstalling hydraulic components on page 427, torque the relief valve to 45 N•m (33 lb-ft). Refill the fluid and test loader operation to confirm the noise is gone.
Manual Section: Hydraulics Repair p. 427Forward or reverse drive surges and creates an erratic on and off motion during smooth travel.
Test the HST forward and reverse pedal potentiometer input voltage on page 258. Verify the sensor reads exactly 5.0 ± 0.2 volts. Replace the potentiometer if out of spec. Inspect the pedal linkage for wear or binding and lubricate pivot points to ensure smooth directional control.
Manual Section: Electrical Circuit Operation and Diagnosis p. 258Loose loader mast and frame bolts create heavy stress concentrations and cracked bell or transmission housings.
Inspect the bell housing for hairline cracks. Remove the loader frame bolts and check the mounting holes for elongation. Replace damaged hardware and tighten the M10 steel bolts to 52 N•m (38 lb-ft) as noted on page 14. Weld or replace the housing if cracked and retest.
Manual Section: Loader Repair p. 14Electrical starting circuit faults create a sudden no crank and no start condition.
Test the battery voltage to ensure it reads a minimum of 12VDC as specified on page 113. Inspect the battery cables for corrosion and clean the terminal connections. Check the standard alternator rating of 40 amps to confirm charging system health before replacing the main starting relay.
Manual Section: Electrical Circuit Operation and Diagnosis p. 113Frequently Asked Questions
What is the meaning of the John Deere 110 error code '• - • •'?
The flash sequence '• - • •' on the HST status light indicates a problem with the Forward Pedal Potentiometer. This means the voltage signal is out of range or the input is not calibrated, leading to no drive in either direction. The recommended action is to get the signal in range and recalibrate the potentiometer. p. 145
What error code indicates that the John Deere 110 won't move?
If the John Deere 110 won't move and the HST status light flashes '• - • •', it indicates a problem with the Forward Pedal Potentiometer. This issue, where the voltage signal is out of range or input is not calibrated, results in no drive in either direction. The solution involves getting the signal in range and recalibrating the potentiometer. p. 145
How do I reset the hydraulic code on a John Deere 110?
For HST control system service codes, such as those related to potentiometers, the reset action involves cycling controller power to clear the code after ensuring the signal is back in range or recalibrating the potentiometer. For example, after correcting a Forward Pedal Potentiometer issue, cycle controller power to clear the code. p. 145
How do I reset the John Deere 110 HST control system to factory specifications?
To reset the HST control system to factory specifications, enter the automatic calibration mode by moving the 10-amp fuse from the F11 (storage) position to the F12 socket with the key switch in OFF position. This process resets all controller values to zero, so the calibration procedure must be completed before driving the tractor. p. 265
What are the general torque specifications for M10 metric fasteners on the John Deere 110?
For M10 metric fasteners on the John Deere 110, the lubricated torque value is 43 N•m (32 lb-ft) and the dry torque value is 55 N•m (40 lb-ft). These values are for general use and include a ± 10% variance factor. p. 13
