The water pump, the radiator coolant, 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 the 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 belt pulley, and then the radiator fan, which rotates together with the belt pulley, providing the air movement needed to cool the radiator during engine operation.

  • part number: 1A021-73030,

The most common problems and faults of the water pump are the bearing seizure , which is subjected to high rotational speeds and because the elements that directly cooperate with the pump, such as the pulley and the fan, which are not always properly balanced. Too tight a belt , worn belt , too loose V-belt, V-belt installed at the wrong angle , poor lubrication or lack of lubrication are other causes that cause water pump damage. The first signs of water pump damage or signs of improper operation are an unusual sound from under the hood, a coolant stain under the tractor or temperature jumps visible on the dashboard gauges.

Questions & Answers

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

User
Ekspert Traktor.com.pl – Doradca techniczny • 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

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
Ekspert Traktor.com.pl – Doradca techniczny • 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.
