Just got in a 2010 Drash HVAC unit with the 20kw generator set-up. Looking over everything and find the side of the block is blown out, due to a thrown rod. It's hard to believe because the unit still looks new with less than 100 hours on it. Does anyone have a source for the Perkins 404D-22T engine that's in the units. Caterpillar uses the same motor, which is a CAT 3024C. Of course I'm looking on ebay and all the other places but wanted to see if anyone knew of a different vendor or may have one sitting around.
