Earlier K with a D140801 or Commercial 324-9120-108 was wandering if anyone had tried D149283 or Commercial 324-9120-175 for a later K on the earlier s/n.
You can use either.D149283 is the updated part number .
Yep, both D149283 and D140801 are hydraulic pump part numbers for CASE 580K, 580SK and 580SL backhoe loaders. They are interchangeable.
