The Komatsu Crawler Loader D20S-7-M and D21S-7-M are powered by reliable Yanmar Engine 4TNE94 and Komatsu Engine 4D94E, respectively. These engines require regular maintenance to ensure optimal performance and longevity. One crucial component that needs to be checked and replaced periodically is the main bearing set. The YM729900-02801 (or 72990002801) main bearing set is designed to fit these specific models and engines, making maintenance easier and more precise.

The main bearing set comes with 5 pairs of bearings, providing ample coverage for the engine block. The bearings are made of high-quality materials, ensuring strength and durability in the face of high engine loads and heat. Aside from the main bearings, the package also includes four thrust plates, also made of durable materials. Thrust plates help to reduce friction and wear between the crankshaft and block, ensuring smoother operation and longer lifespan.

To ensure that you get the right bearing set for your engine, it is recommended that you check your engine model and specifications first. The YM729900-02801 main bearing set is compatible with a range of Yanmar and Komatsu engine models, including 4TNE94-ACG, 4TNE94-DBK, 4TNE94-DBW, 4TNE94-DBWK, 4TNE94-G1A, 4TNE94-HLB, 4TNE94-HYB, 4TNE94-SA, 4TNE94-SFW, 4TNE94-WI, 4TNE94-EIK, 4TNE94-SF, 4D94E-1A, and 4D94E. If you need other specifications such as 0.25 or 0.5, please contact us before placing your order.

Regular maintenance is vital to ensure that your engine operates at its peak efficiency and longevity. Regularly checking and replacing worn-out components such as the main bearings and thrust plates can go a long way in prolonging the lifespan of your engine. With the YM729900-02801 main bearing set, you can be assured of quality and compatibility, making maintenance a breeze.
