Product description

Valve Guide TRW 81-25100

Description

The TRW 81-25100 valve guide is an essential component of the engine’s valve train, ensuring precise guidance of the valve stem inside the cylinder head. It prevents excessive wear of the valve and seat, maintaining optimal combustion chamber sealing and prolonging engine life. Manufactured from high-grade alloy steel, this valve guide provides excellent resistance to heat, wear, and friction, making it ideal for heavy-duty applications. TRW’s advanced production process guarantees accuracy and durability even under extreme operating conditions.

Technical Data

  • Material: heat-treated alloy steel
  • Inner diameter matched to the valve stem
  • Outer diameter fitted to the cylinder head seat
  • Operating temperature resistance above 250°C
  • Precision machining ensures minimal clearance
  • Part number: 81-25100
  • Manufacturer: TRW Engine Components

Application

The TRW 81-25100 valve guide is used in diesel and petrol engines fitted to trucks, buses, and construction machinery, particularly MAN engines. It is suitable for use during engine overhauls, cylinder head refurbishments, and as a service part replacement in professional repair workshops. Fully interchangeable with OE parts and high-quality aftermarket alternatives.

Properties

  • High resistance to wear and abrasion
  • Stable valve guidance at high RPMs
  • Reduced energy loss and exhaust emissions thanks to maintained sealing
  • Easy installation with perfect fit
  • Compatibility with intake valves following OEM standards
  • Extended engine service life through minimized clearances

Opinion 5/5

Zakupiony komplet siłowników do Liebherr 564 był w doskonałym stanie, zgodnie z opisem i przesłanymi zdjęciami. Obsługa na wysokim poziomie, bardzo profesjonalna i pomocna – rewelacja. Co więcej, w kontakcie z firmą otrzymałem osobistego opiekuna, który zajmował się sprawą od początku do końca, mogłem również liczyć na bezpłatne doradztwo przy montażu. Szkoda, że w obecnych czasach nie spotyka się zbyt wielu firm z tak profesjonalnym podejściem do klienta. Gorąco polecam.
