Frequently Asked Questions

What filters does a John Deere 644A wheel loader need?

The 644A uses air filtration, engine oil, and hydraulic filters. We carry secondary and safety air filters, engine oil filter cartridges, and a hydraulic pump stroke control valve filter element for this machine.

What is the difference between a secondary and safety air filter on the 644A?

Both are inner protective elements that guard the engine against dust that bypasses the primary filter. We offer both a secondary air filter and a safety air filter option for the 644A, so match the part number to your air cleaner setup.

Will these 644A filters fit other John Deere loaders?

Several of these filter elements carry part numbers that fit multiple John Deere machines, but fitment can vary by serial number and configuration. Confirm by matching the part number, or call our parts team at (800) 909-7060.

How often should I replace the engine oil filter on a 644A?

Replace the engine oil filter cartridge at each scheduled oil change according to your service interval. We carry the oil filter cartridge along with the air and hydraulic filters needed for a full service.
