Frequently Asked Questions

What does the hydraulic pump coupler do on a John Deere excavator?

The hydraulic pump coupler connects the engine flywheel to the main hydraulic pump input shaft and transfers rotation between them. Its rubber flex element absorbs torsional vibration and shock so the drivetrain runs smoothly. Broken Tractor carries flex couplers and rubber couplings across John Deere C, D, E, and G series excavators and their earlier counterparts.

Which pump coupler fits a John Deere 120C excavator?

The 120C splits by serial number, so you need to match your machine before ordering. We carry a 3-bolt rubber pump coupler (SKU 4627118) for 120C units after serial number 034261, and a rubber flex coupling (SKU 4334891) for 120C units before 034261. Check your serial number against these breaks to pick the right one.

Which coupler fits a John Deere 490E excavator?

The 490E also splits by serial number. We carry a rubber coupler (SKU 4239375) for 490E machines before SN 024999, and a coupler (SKU 4310056) for 490E machines after SN 25000. Confirm your serial number to order the correct part.

Do you have a hydraulic pump coupler for a John Deere 330C excavator?

Yes, Broken Tractor carries a Hydraulic Pump Flex Coupler (SKU 4216944) that fits the 330C along with the 892DLC, 892ELC, 330LC, 330LCR, 370, 370C, and 3554. If you are unsure which coupler matches your machine, match the part number or confirm your fitment with our parts team at (800) 909-7060.

What coupler fits the John Deere G series excavators like the 210G and 135G?

We carry a Hydraulic Pump Flex Coupler (SKU FYB00000115) that fits a wide range of D and G series machines including the 130G, 135G, 210G, 250G, 290G, 2144G, 2154G, 2156G, 2654G, and 2656G, plus several D series units.
