Description
When your transmission starts getting sluggish or you notice the hydraulics aren’t responding like they used to, there’s a good chance your oil pump gears have seen better days. This transmission oil pump gear set is 12.20mm thick and keeps the vital oil flowing through your transmission and hydraulic systems. Without proper oil circulation, your powershift won’t shift smoothly and your hydraulics will feel weak—problems that’ll slow you down when there’s work to get done.
What You’re Getting
- Precision-machined gear teeth that mesh smoothly for consistent oil flow
- 12.20mm thickness specification ensures proper pump clearances and pressure
- Hardened construction that handles the constant rotation and pressure of transmission work
- Complete gear set so you’re not mixing worn and new components
- Drop-in replacement that works with your existing pump housing
Built for Real Farm Work
These gears fit a wide range of John Deere’s most popular tractor series—from the 5020 utility tractors perfect for hay work and loader duties, up through the powerful 7020 series machines that handle heavy tillage and planting. Whether you’re running a 6420 through bean fields or using a 7520 for deep tillage work, this pump keeps the transmission oil moving where it needs to go.
Made to Last
Farm transmissions work hard, cycling through ranges all day long while powering hydraulic systems that run loaders, three-point hitches, and remotes. These gears are built to handle that constant use, with materials and tolerances that stand up to the heat and pressure inside your transmission case.
Installation Notes
You’ll need to split the transmission case to access the oil pump, so this is typically a winter shop job rather than a field repair. Clean everything thoroughly during reassembly—even small debris can damage new gears. Check your pump housing for wear while you’re in there, and replace the pump gaskets while everything’s apart.
