Hydraulic pump couplers for Caterpillar excavators, covering a wide range of compact and full-size machines from the 311C through the 336D. These couplers connect the engine to the hydraulic pump and are critical to maintaining proper hydraulic system function — worn or failed couplers lead to pump slippage, vibration, and loss of hydraulic pressure.
