Description
When your John Deere transmission starts leaking oil or making noise, it’s often the internal oil pump that’s given up the ghost. These tractors rely on properly maintained transmission and hydraulic systems for loader work, PTO operations, and precision farming tasks. This transmission oil pump keeps everything inside properly lubricated and pressurized, which means smoother shifting, proper hydraulic function, and a longer-lasting drivetrain.
What You’re Getting
- Direct replacement oil pump built to original specifications
- Quality construction that handles the heat and pressure of transmission work
- Includes mounting hardware and small bearing assembly for complete installation
- Engineered to maintain proper oil flow and pressure throughout the transmission
Built for Real Farm Work
Your John Deere 20 or 30 Series tractor is likely a trusted workhorse on your farm. Whether you’re using a 1030 for utility work, operating a 2030 with a loader, running hay equipment with a 2130, or cultivating with a 2240, this pump keeps your transmission operating smoothly. It also fits 40 Series models like the 2440 and 2640 that handle heavier field work and larger implements.
Made to Last
Quality bearings ensure smooth operation without play or noise. The impeller is designed to provide optimal flow rates for these specific engines. All components are manufactured to meet or exceed original specifications for dependable service. The 80mm outside diameter bearing included with this pump is precision-made to handle the loads and speeds your transmission demands.
Installation Notes
Plan on draining the transmission oil before starting this job. The pump is accessed from inside the transmission case, so you’ll need basic mechanical skills and clean working conditions. Any dirt or debris that enters during installation will damage your new valve and potentially your entire hydraulic system. Remove the old valve carefully, noting the position and routing of all hydraulic lines. Take your time, use new gaskets, and refill with fresh transmission fluid when you’re done.
