Frequently Asked Questions

How do I confirm the right connecting rod for a John Deere 540E or 648E skidder?

Match the rod by its casting mark. Our AR93341 connecting rod fits 540E, 548E, 640E, and 648E when the rod is marked R71074, so verify the casting mark on your existing rod before ordering. If you are unsure, match the part number or confirm with the parts team.

Does the RE50657 bare cylinder block fit a John Deere 710C or 748G forestry machine?

Yes, the RE50657 bare cylinder block is listed for the 710C and 748G among other applications, and it covers 6059 and 6068 platform components. Fitment on these blocks can depend on serial number, so check the part number against your engine or confirm with the parts team before ordering.

Will the RE500917 torsional damper fit a John Deere 750J or 850J tracked machine?

Yes, the RE500917 torsional damper is listed for the 750J and 850J, along with 753G, 759G, 903G/J, 953G/J, and 959J forestry machines. Some applications carry a serial number range, so match the part number or confirm with the parts team if your machine falls near a break.

What flywheel ring gear fits a John Deere 610B or 640E skidder?

We carry more than one ring gear covering forestry ranges. The R54503 ring gear fits models including 610B, 640, 640D, 640E, and 640G, while other ring gears such as T20088 and R28811 cover different model ranges. Match the part number to your engine to be sure you get the correct tooth count and fitment.

Do you sell block heaters for John Deere forestry engines like the 750C or 850C?

Yes, Broken Tractor offers the RE227949 engine block heater, which is listed for applications including the 750C, 750J, 850C, and 850J. Because block heater fitment ties to the specific engine, verify the part number against your machine before ordering.
