Description
When your tractor starts running hot or you’re losing coolant, it’s usually the water pump calling it quits. This is one of those jobs you don’t want to put off—an overheated engine can turn a simple repair into an expensive rebuild. This TISCO water pump gets your cooling system back to doing what it does best: keeping that diesel engine at the right temperature while you’re working.
What You’re Getting
- Complete water pump assembly that moves coolant through your engine like it should
- Built tough for diesel engines that work hard and run long hours
- Direct replacement for John Deere casting numbers R51039 and R55758
- Comes without hub and pulley so you can transfer yours from the old pump
- Quality TISCO construction that holds up to farm conditions
Built for Real Farm Work
This pump fits a solid range of John Deere tractors from the smaller 820 and 830 models up through the 2440. These are the tractors you see doing everything from loader work around the barn to field cultivation and hay operations. Whether you’re running a compact operation or handling bigger acreage, these machines get the job done.
Made to Last
TISCO builds this pump to handle the constant demands of diesel engines that run in dusty, hot conditions. The impeller and housing are designed to move coolant efficiently while standing up to the temperature swings and vibration that come with farm work.
Installation Notes
Since this pump comes without the hub and pulley, you’ll transfer those from your old unit. Make sure to clean the mating surfaces and use fresh gaskets for a good seal. After installation, fill the system slowly and run the engine to purge any air pockets—trapped air is the enemy of proper cooling.
