About the rubber coupling: Rubber coupling is one of the most important parts in an excavator. It’s in stalled on the hydraulic pump. It’s between the hydraulic pump and the engine. The rubber coupling for the excavator is an engine drive coupling. It transmits the power from the excavator coupling to the hydraulic pump. When an engine starts, there is a lot of vibration. These vibrations are generally attenuated by engine damping rubber (also call the rubber engine mount or rubber engine pillow) and couplings. A good shock absorber (the engine mounts) and coupling can greatly extend the working life of an excavator engine and hydraulic pump. A high-quality coupling will be made of high-quality raw materials. The raw material for making couplings is generally rubber, because rubber has excellent shock absorption.
