Product description

The water pump, the coolant pump , is one of the most important elements of the engine cooling system and this method of cooling is commonly called water cooling . The engine block and the engine head are elements that heat up to very high temperatures during operation and it is these that we want to cool with coolant during operation. Special water channels are bored in the engine and the head for the circulation of water, which, in order to be re-injected into the engine water channels. The circulation of the coolant is possible thanks to the water pump , which is most often placed between the radiator and the engine and is driven by a V-belt from the alternator. To the pump flywheel, we screw in the following order the pulley, and then the radiator fan, which rotates together with the pulley, providing the air movement needed to cool the radiator during engine operation.

Questions & Answers

Why is regular filter replacement (oil, air, fuel) crucial for a mini tractor?

User
Traktor.com.pl Expert – Technical Advisor • 17.02.2026
Regular filter replacement is the easiest way to extend the life of an engine from brands like Kubota or Yanmar. The oil filter removes metallic contaminants generated during operation, the air filter protects the cylinders from field dust, and the fuel filter prevents water and dirt from damaging the precision injection system. We recommend replacing filters every 50-100 operating hours or at least once per season to ensure optimal engine performance.

How to properly select and sharpen mower blades for a Japanese tractor?

User
Traktor.com.pl Expert – Technical Advisor • 17.02.2026
When selecting mower blades, consider the mower deck model and the blade length and center bore diameter. Maintaining blade balance is crucial when sharpening – an unbalanced blade causes vibrations that damage the hub bearings. Remember that sharp blades mean healthier grass, a cleaner cut, and less strain on the engine of your Iseki or Mitsubishi tractor.

How to identify the correct V-belt size and how to care for it?

User
Traktor.com.pl Expert – Technical Advisor • 17.02.2026
It's best to read the markings on the side of the old V-belt. If they are illegible, measure the belt width and its outer length (La). On Shibaura and Hinomoto tractors, it's important to regularly check the belt tension – too loose a belt will cause slippage and faster wear, while too tight a belt can cause alternator or water pump bearing failure.
