Crawler or backhoe..?? They made both. If it's a crawler, what series 310, and you'll need the serial number off of it to be sure to get the right one. Here is a link to Case Construction, and a list of 310 crawlers. You'll have to pick which one is your model, and click on it. When the next window opens, select engine. Then scroll down through the function groups, until you see the fans, water pump, etc. You'll see the part number listed for each one. Use that number to search for a used, or aftermarket one. New one's from Case are N/A, and would probably cost a small fortune if they did stillcarry them.
