Main engine bearings are semicircular rings that are mounted in special grooves (holders) in the engine block, between the crankshaft (main shaft) and the engine block (applies to the central shaft journals) in order to eliminate play that occurs during engine operation. Main bearings, bearing the shaft, ensuring the proper position of the shaft relative to the engine block so that the generated power is transmitted as smoothly as possible.

Questions & Answers

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

User

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?

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.
