Here’s some pics of a Caterpillar 834H RTD (Rubber Tire Dozer) cooling package we delivered back to one of the mines after we gave it a complete rebuilding service. The hardnose, or nosecone, contains AMOCS type radiator sections (cores), an oil cooler, the aftercooler, hydraulic fan motor, fan blade & electrical wiring harnesses. We completely disassemble hardnoses down to the raw grill guard shell for cleaning, any necessary welding & full reconditioning. Each part is cleaned, inspected for integrity, repaired & tested before final assembly as a complete cooling package.
