Product description

Engine valve seal (valve IN 14601-13110, valve EX 14601-13120) with an inner diameter of 6 / 10.50 mm and a height of 9.40 mm for Kubota tractors with Kubota D722, Kubota Z482 and other engines.

The valve stem seal is a rubber gasket designed to ensure a tight seal between the valve and the camshaft chamber. The valve seal (named after its inventor) is designed to prevent engine oil from entering the cylinders.

Dimensions:

  • inner diameter: 6 / 10.50 mm,
  • height: 9.40 mm,
  • part numbers: 11420-13150.

Engine models :

Kubota :

  • Kubota D722,
  • Kubota Z482.

The first signs of valve stem seal damage are loss of engine oil and increased smoke coming out of the exhaust pipe when starting the engine, while driving when increasing engine speed. A worn valve stem seal should be replaced with a new one as soon as possible.

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.
