Frequently Asked Questions

What electrical parts do you carry for John Deere dozers?

Broken Tractor carries alternators, voltage regulators, starter motors, solenoids, ignition switches, sending units, pressure switches, and dash cluster gauges for John Deere crawler dozers. These cover charging, starting, sensing, and instrument functions across the 350, 450, 550, 650, 700, and 850 Series. We offer both new and used electrical parts.

Do you have alternators for both 12V and 24V John Deere dozer systems?

Yes, we carry alternators and voltage regulators for both 12V and 24V John Deere dozer charging systems. Because voltage differs between machines and generations, confirm your system voltage before ordering. Match the part number to your unit or contact the parts team to verify fitment.

Will these electrical parts fit my John Deere 450C or 650G dozer?

Many of our electrical and gauge parts fit across John Deere dozer generations including the 450 Series and 650 Series, but fitment often depends on model, serial number, and system voltage. Match the part number to your machine to be sure it is correct. If you are unsure, call our parts team at (800) 909-7060 to confirm.

What gauges are available for John Deere dozer dash clusters?

Broken Tractor offers temperature, oil pressure, fuel, and hour meter gauges for John Deere dozer dash clusters. We also carry the sending units and pressure switches that feed accurate readings to these gauges. Confirm the gauge matches your specific model and cluster before ordering.

Should I replace or repair a bad sending unit on a John Deere dozer?

A faulty sending unit or pressure switch that gives inaccurate temperature, oil pressure, or fuel readings is usually replaced rather than repaired, since these sealed sensors are not serviceable. We carry replacement sending units and pressure switches for John Deere dozers. Match the part number to your existing sensor to get the correct replacement.
