I have a 2003 Daewoo 802 Plus, and the Hydraulic oil cooler on the rear of the engine has a bad leak. It needs to be replaced but I'm having trouble locating one. The oil cooler was made by a company called "karmazin", but I have had no luck contacting them I belive they have gone out of business. Bobcat and Dossan dealers are giving me prices from 1,500-1,700$, can I get this part for a better price somewhere else? Tom
