Transmission Oil Pump for John Deere 40, 50, and 55 Series Tractors

Description

When your transmission starts slipping gears or you notice jerky hydraulic operation, there’s a good chance your oil pump isn’t moving fluid like it should. Your John Deere’s hydraulic pump is the heart of your three-point hitch, loader, and remote hydraulics. When seals wear out, you don’t just lose fluid – you lose the pressure needed to lift heavy implements, operate your loader smoothly, or run hydraulic motors efficiently. This replacement oil pump gets things flowing properly again, restoring the power and control you need for demanding farm work.

What You’re Getting

• Thick pump design with keyway for positive drive connection – no slipping under load
• Direct replacement that fits right where your old pump was – no modifications needed
• Quality construction built to handle the constant demands of hydraulic operation
• Precise machining ensures proper clearances for optimal oil flow and pressure

Built for Real Farm Work

These John Deere 40, 50, and 55 series tractors are proven workhorses that often have decades of hard service. Whether you’re running a compact 1040 for chores, working a 2650 in row crops, or pulling heavy implements with a 3350, this pump keeps your transmission and hydraulic systems properly lubricated and pressurized for smooth, reliable operation.

Made to Last

Farm work doesn’t stop for failed pumps, so this one’s built tough. The thick design with keyway connection ensures positive drive engagement even under high loads. Quality materials and precise manufacturing mean it’ll handle the heat, pressure, and contamination that come with agricultural use while maintaining proper flow rates season after season.

Installation Notes

This is a direct replacement, but plan on 3-4 hours for a complete rebuild. Cleanliness is absolutely critical – any contamination will destroy new seals quickly. Make sure to clean all mounting surfaces thoroughly and use fresh hydraulic fluid when refilling the system. The keyway alignment is straightforward – just match it up with your drive shaft.
