The company added that engine sales also improved for Caterpillar by 31% but not as much as machinery sales. Caterpillar says its facilities in Tokyo, Akashi and Sagami were not damaged by the recent earthquake in Japan but added production was fluctuating from "day to day" because of the disaster. Caterpillar says its own supply chain from Japan hasn't been affected by the disaster but is looking to source components from other sources to prevent a shortfall in the longer term. The Caterpillar Foundation will add a $1 million grant to the American Red Cross for disaster relief efforts in Japan and will match up to $500,000 in employee contributions.
