198-30-56132 pad Komatsu D375 bulldozer spare parts

The Komatsu D375 gasket 198-30-56132 is a “sealing and buffering core” for chassis component connections. It fits snugly against the mating surfaces of components, effectively preventing leakage of oil, mud, and dust. At the same time, it buffers the vibration and friction during component operation, protecting the mating surfaces from wear. It is specially designed for various connection parts of the chassis of Komatsu D375A-2/A-5/A-6/A-8 models, avoiding leakage and component wear caused by gasket aging and damage, ensuring normal equipment operation, and improving construction efficiency.
This product strictly adheres to Komatsu’s original standards and references the D375 series (474kW power, 72-ton operating weight) chassis component specifications. It utilizes high-strength sealing steel with a corrosion-resistant coating, offering advantages such as tight sealing, wear resistance, corrosion resistance, and easy installation. Through precision stamping and aging treatment, it achieves accurate dimensions and high flatness, closely matching the mating surfaces of original components for direct installation. This effectively reduces downtime losses, extends the lifespan of chassis components, and lowers maintenance costs. Widely used in mining, earthmoving, and infrastructure fields, it is a core consumable for chassis component maintenance.
