YNF17245 672-5251 Bushing Excavator Engine Bearing Sleeve / Heavy-Duty Bushing Replacement

The YNF17245 bushing, replacing OEM 672-5251, is a high-precision bearing sleeve designed to support rotating and reciprocating components in excavator engines and major mechanical assemblies. Its main function is to reduce friction, maintain alignment, and minimize wear between metal contact surfaces, ensuring stable operation under continuous heavy-load conditions.

Manufactured from high-strength alloy and processed with precision machining, the YNF17245 bushing offers excellent dimensional accuracy, high hardness, and strong resistance to abrasion and deformation. This results in longer component life, reduced noise, and improved engine reliability, even in harsh construction, mining, and earthmoving environments.

The 672-5251 bushing is widely chosen by engine rebuilders, equipment repair shops, and parts distributors due to its stable performance and OEM-level compatibility. Replacing worn bushings helps restore mechanical efficiency, reduce internal damage, and prevent costly engine failures.
