Here’s some before and after pics of some shell-and-tube hydraulic brake system oil coolers off of a Caterpillar 793C haul truck. These coolers came in for repairing and rebuilding as they were filthy dirty and leaking. We completely disassembled them and then boiled them out in our ultrasonic cleaning tank and hot tank cleaning cabinet. We then rodded the tubes out and performed any necessary repairs. We then pressure tested the coolers in our test tank to ensure they have absolutely no leaks. Once we pressure tested them and made sure they had no leaks we then assembled the complete oil cooler assemblies with all new gaskets and seals. The small and shorter oil coolers are Caterpillar part numbers 243-5770 or OR-9850 while the longer cooler is part number 243-5774. For all of your oil cooler, heat exchanger, and heat transfer needs please give us a call.
