418-12-41111 Coupling for Komatsu Wheel Loaders | Fits WA200-5, WA200-5L, WA250-5, WA250-5L
The 418-12-41111 coupling is a high-performance flange coupling (non-hub type) engineered as a direct OEM replacement for Komatsu wheel loaders WA200-5/WA200-5L/WA250-5/WA250-5L (also fits WA200-6/WA250-6/WA270-5).
· Function: This flexible coupling is installed between the engine flywheel and the hydraulic pump to transmit engine power smoothly and accommodate slight misalignments and vibrations.
· Design: The part number often cross-references with other Komatsu numbers like 418-12-31110 and 418-12-61110, which are part of the same assembly.
