Frequently Asked Questions

What filters does the John Deere 644C need for service?

The 644C uses a fuel filter cartridge, a spin-on engine oil filter, and a fuel/water separator, plus a hydraulic pump stroke control valve filter element. Broken Tractor carries each of these for the 644C. Match the part number to your machine to confirm the right fit.

How do I find the right fuel filter for my 644C?

Match the fuel filter cartridge or fuel/water separator to your machine by part number, since filters can vary by serial number range. We carry both the AR86745 fuel filter cartridge and the AT81478 fuel/water separator that service the 644C. Call (800) 909-7060 if you need help confirming the correct one.

Do these filters fit other John Deere machines besides the 644C?

Many of these filters are shared across several John Deere construction and forestry machines, so the same part often services other models as well. We list only 644C wheel loader fitment here. Always verify by part number for your specific application.

What is the difference between the fuel filter cartridge and the fuel/water separator?

The fuel filter cartridge cleans fuel of fine contaminants, while the fuel/water separator removes water and larger debris before fuel reaches the injection system. Both are used on the 644C and should be replaced on their service intervals. We offer both for this loader.
