Description

When your temperature gauge starts climbing or you notice coolant puddles under your John Deere, a failing water pump is usually the culprit. These tractors often work in demanding conditions where overheating can quickly escalate from an inconvenience to major engine damage. This replacement water pump gets your diesel engine’s cooling system back to proper operation so you can get back to the work that needs doing.

What You’re Getting

Complete water pump assembly with integrated cast iron 5-inch pulley for reliable belt drive
Single groove pulley design that matches your tractor’s original configuration
Heavy-duty construction built to handle the demands of diesel engines and field conditions
Direct replacement that fits without modifications or adapters
Quality bearings and seals designed for long service life in farming applications

Built for Real Farm Work

This pump fits a range of John Deere utility and compact tractors including the 820, 830, 1020, 1520, 1530, 2020, 2030, and early 2040/2240 models. Whether you’re running a 1020 for light utility work, using a 2030 with a loader for barn chores, or depending on a 2240 for cultivation work, proper cooling keeps these diesel engines running strong through long work days.

Made to Last

The cast iron pulley and robust pump housing are built to withstand the vibration, heat cycles, and demanding conditions that farm tractors face. Quality internal components resist wear from coolant and contamination, while the integrated pulley design eliminates the potential failure point of a separate pulley attachment.

Installation Notes

Begin by draining the cooling system completely. Clean the mounting surface thoroughly to ensure proper gasket sealing. After installation, fill the system slowly to avoid air pockets. Run the engine with radiator cap off until the thermostat opens, then top off coolant. If your old pulley has been squealing, check belt tension and alignment while you’re at it.
