Here’s some pics of a hardnose, or nosecone, assembly off of a Caterpillar 993K loader. This cooling package utilizes the Caterpillar AMOCS radiator cores for engine cooling. Other cooling system components in this package include two aluminum aftercoolers as well as two aluminum oil coolers. The fins of the CAC’s, or charge air coolers, & the oil coolers are pretty well plugged & fouled externally. This external blockage is drastically inhibiting airflow through the fins which leads to engine overheating. We’ll get it all cleaned up, repaired & post more pics as the rebuild progresses.
