When you’re fixing a leaking water pump, there’s always that moment when you’re staring at the old mechanical seal wondering if you can get away with reusing it. The answer is simple – don’t risk it. This old-type water pump seal is what keeps coolant where it belongs and prevents those expensive coolant leaks that can turn into costly engine damage if ignored.
What You’re Getting
- Proper sealing design that handles the pressure and temperature swings of diesel engine cooling systems
- Durable construction that won’t fail under the constant vibration of tractor work
- Direct replacement for original equipment – no modifications needed
- Compatible with both QTP-1331 and QTP-41226 water pump assemblies
Built for Real Farm Work
This seal works with a wide range of Massey Ferguson tractors from the compact 35 series utility tractors up through the heavy-duty 600 series machines, plus Ford Dexta and Major models. Whether you’re running a 165 with a loader or pulling heavy implements with a 690, your cooling system has to manage serious heat generation. These machines handle everything from field cultivation and hay production to livestock management, and reliable cooling is critical for preventing costly engine damage during heavy tillage, harvesting, and continuous PTO operations.
Made to Last
The mechanical seal is critical – don’t reuse even if it looks okay. This seal uses durable materials and precision engineering to ensure long-term reliability under the demanding conditions of agricultural work. Farm equipment runs hard and long, and a quality seal prevents the kind of coolant leaks that leave you stranded during harvest or create slippery, dangerous conditions around your tractor.
Good to Know
Always use new seals and gaskets during assembly. Pack the bearing with waterproof grease, consider replacing the thermostat while you’re working on the cooling system, and use this opportunity to flush your cooling system and check all hoses. A properly rebuilt pump with fresh seals should give another 20+ years of service.
