Caterpillar's 300 series excavators dominate the US and North American heavy construction market. The CAT 320D, 323D, 325D, 330D, and 336 platforms use precisely calibrated engine anti-vibration mounts to isolate the C7, C9, and C13 engines from the main frame. Key Caterpillar engine mount part numbers available from our stock include 211-4987, 227-0172, and 358-0286.
