Rubber-to-steel isolation mount for Caterpillar machinery — a direct replacement for the original Caterpillar 109-9350. It is bolted between the engine or a component and the frame to isolate vibration and noise. The rubber element perishes over time: it cracks, softens or separates from the steel, so vibration is transmitted to the frame and noise increases. Replaced when the mount shows cracks, sagging or oil damage. Supplied as one mount. Confirm the part number and machine model before ordering.
