Frequently Asked Questions

How do I know which John Deere 550H or 650H oil cooler fits my dozer?

Fitment on the 550H and 650H splits by serial number. Broken Tractor carries a hydrostatic cooler for units before serial 910569 (AT301886), a mid-serial cooler for 910570 through 924717 (AT227770), and a cooler for units after 924718 (AT303832). Match your machine serial number to the correct part, or confirm with our parts team before ordering.

Why does the JD 750B oil cooler come in more than one version?

The 750 and 750B coolers split at a serial break. We carry an early 13-1/4 inch arm-style cooler for the 750 after serial 374031 and 750B before serial 745806 (AT80352), and a separate cooler for the 750B after serial 745807 along with the 750C and 750C-II (AT116798). Check your serial number to pick the right one.

What is the difference between the direct drive and torque converter oil cooler on a JD 450G?

John Deere used different coolers depending on the drive type. Broken Tractor offers a direct drive hydraulic oil cooler covering the 450G through 650G range (AT104588) and a separate torque converter cooler for the 450G and 455G after serial 840461 (AT159742). Verify your drive configuration and serial number before ordering.

Do you carry a hydrostatic oil cooler for the John Deere 750K and 850K dozers?

Yes. We carry a hydrostatic oil cooler for the 750K within serial numbers E216966 through E270478 (AT372229) and a hydrostatic oil cooler for the 850K (AT367173). We also offer standard hydraulic oil coolers for these models, so match the part number to your cooler circuit and serial range.

What John Deere dozers does the 8 plate engine oil cooler fit?

The 8 plate engine oil cooler (AR55394) fits John Deere dozers including the 750C, 750J, 850B, 850C, and 850J, plus a range of loaders and other equipment. Because it spans many machines, confirm the part number matches your engine setup before ordering. You can also call our parts team at (800) 909-7060 to verify fitment.
