Used in the transmission systems of Komatsu construction machinery, the transmission gear group spring with part number 56D-15-12710 (also formatted as 56D1512710) is designed to be compatible with WA320-3, WA380-3, WA380-6, WA430-5, WA430-6, WA470-5, and WA470-6 loader models. Positioned within the internal transmission gear shifting mechanism, this component supports the group elements in operating under the correct pressure.
It is important to examine the original numbers on the removed old component to confirm part compatibility during transmission group overhauls and maintenance work. During assembly, it should be checked whether the gear group operates compatibly with other spring and washer elements.
To ensure the system operates smoothly, make sure that the spring coded 56D-15-12710 is fully seated in its housing during part replacement.
