Product description

Copper washer, injector gasket ( 40052877 ) with an inner diameter of 12 mm , an outer diameter of 17.40 mm and a thickness of 1.40 mm for LS Tractors of the LS i28, LS R28i, LS XJ25 series and others.

The washer is the basic element that occurs in all screw connections, and their main task is to separate the nut from the connected element. Another function is to prevent self-loosening of screws in threaded connections. In addition, copper washers can act as sealing and are used due to the plasticity of the metal, high anti-corrosion properties. We divide the washers into three groups:

  • ordinary (protective, increasing the pressure surface of the screw),
  • securing against unscrewing (spring),
  • leveling, spacing, copper sealing (for leveling when the joined elements are not perfectly smooth),
  • special sealing.

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
Ekspert Traktor.com.pl – Doradca techniczny • 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
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.
