Frequently Asked Questions

What filters does a John Deere 644K need?

The 644K uses fuel filters, fuel/water separators, primary and secondary air filters, hydraulic filters, and an engine oil filter. Broken Tractor carries all of these service filters for the 644K wheel loader. Match the part number to your machine to confirm the correct fit.

Which hydraulic filter fits the 644K?

We carry hydraulic spin-on filters that fit the 644K, including a K-Series hydraulic filter used across the 644K, 744K II, 824K, and 844K wheel loaders. If you are unsure which one your machine takes, verify by part number before ordering.

Does the 644K use both a primary and secondary air filter?

Yes, the 644K uses a primary air filter and a secondary (safety) air filter that work together to protect the engine. Broken Tractor offers both elements for the 644K. Replacing them as a set during service is a common approach.

How do I confirm the right fuel filter for my 644K?

Some 644K fuel filters and separators vary by build, so matching the part number to your machine is the most reliable method. We carry spin-on fuel filters and fuel/water separators for the 644K. Call our parts team at (800) 909-7060 if you need help confirming fitment.
