Part of the John Deere Repair Manuals.
Factory service figures for the John Deere 4100 compact utility tractor are settled in TM1630, a 595-page John Deere 4100 technical manual PDF written for the 4100 Gear Drive, Hydrostatic Drive and Narrow Gear Drive. Wiring schematics and harness layouts trace the North American and road homologated electrical systems, and hydraulic schematics show oil routing. The 3TNE74-JKI diesel engine, gear and hydrostatic power trains, steering and brakes each get troubleshooting, theory of operation, tests and adjustments, and repair. Inch and metric torque tables are included. When testing the engine fuel system, confirm at least 29 kPa (4.3 psi) of fuel pressure and a pump flow of 118 cc/min (4 ounces/min). For a glow plug circuit diagnosis, your figures are 0.3 to 0.5 ohms of plug resistance and a 3 second module timer length. Bookmarked and text searchable, the file travels on a laptop or tablet, keeping the hydrostatic power train procedures with you wherever the 4100 sits.

John Deere 4100 Common Problems This Manual Covers
Charging system suspect, alternator belt glazed or cracked and battery voltage reading low
Inspect the water pump/alternator belt and replace it if glazed or cracked, then adjust belt tension (page 47). Recharge a low battery, repair any open circuit in wiring, and repair or replace a defective alternator, per the chart on page 44. Never check battery charge by laying a metal object across the posts, and do not charge a frozen battery; it may explode (page 5).
Manual Section: Diesel Engine Troubleshooting p. 44Glow plug or glow plug module timer suspected on a diesel engine that will not start
Measure each glow plug's resistance against 0.3 to 0.5 ohms, the spec on page 131, and treat any plug outside that range as suspect. Verify the glow plug module timer runs its listed 3 seconds. Recharge a low battery and repair any open circuit in wiring (page 44). Do not charge a frozen battery, and never check charge with a metal object across the posts (page 5).
Manual Section: Electrical - N.A. p. 131Fuel shutoff solenoid will not pull in and hold when the key returns to ON
Test the solenoid by turning the key to START and listening for clicking as you cycle the key; it must pull in and stay in when the key returns to ON (page 47). Confirm the throttle lever gets its full range of motion, stop to stop, before any diagnosis (page 51). If the solenoid still will not hold, work through Fuel Shutoff Solenoid Circuit Diagnosis in the electrical section.
Manual Section: Diesel Engine Diagnosis p. 47Frequently Asked Questions
What are the torque specifications for the wheel bolts on a John Deere 4100?
The torque specification for the rear wheel bolts on the John Deere 4100 is 108 – 127 N•m (80 – 94 lb-ft). p. 512
How do you fix John Deere 4100 diesel fuel system with water or air in the lines, engine will not start?
Check that the filter shutoff valve is in the ON position and drain any water from the filter bowl, following the diagnosis checks on page 47. Replace a clogged fuel filter and replace cracked hoses or loose clamps. Close the fuel filter/water separator shutoff valve before disconnecting any fuel line, and keep open flames and sparks away (page 111). If no fuel reaches the injector pump inlet hose, test the fuel pump. p. 47
How do you fix clogged fuel filter or weak fuel transfer pump on the 3TNE74 engine, showing low engine output?
Replace a clogged fuel filter and clean or replace a clogged air filter, per the chart on page 44. Test the fuel pump next: pressure must reach at least 29 kPa (4.3 psi) per page 62, and flow should hit 118 cc/min (4 ounces/min) per page 63. Check or replace the fuel transfer pump if either falls short. Close the fuel filter/water separator shutoff valve before opening any fuel line, and keep flames and sparks away (page 111). p. 44
How do you fix engine running too hot with the coolant warning lamp lit on the instrument panel?
Check coolant level and look for leaks, then check the thermostat and fan belt tension following the chart on page 41. Clean the radiator screen and inspect hoses, clamps, and radiator cap (page 47). The warning lamp lights when coolant reaches 107 to 113°C (225 to 235°F), page 36. Do not remove the pressure cap while hot; coolant may be above boiling and under pressure, so wear protective clothing and goggles (page 60). p. 41
How quickly can I access this John Deere 4100 manual after buying?
All 595 pages arrive as one searchable PDF at checkout. Read it at the desk, then take the phone out to the machine.
Does this John Deere 4100 manual allow printing?
Yes. Print the pages you need for the job in your own shop, and bin them when they get greasy.
Is the hydraulic system diagrammed in this John Deere 4100 manual?
Included. A hydraulic system diagram shows the main hydraulic layout for the John Deere 4100. You can see one on page 538.
