Here’s some pics of an aluminum radiator we had in for a Grove RT600E crane that was leaking in the tubes of the core from internal plugging, or fouling. The build-up inside the tubes allowed corrosion to take place which ate the tubes up internally causing leaks in the tubes of the core. We cut [...]
Here’s some pics of our machining & heavy equipment repair capabilities. This is the front axle for an 18M Caterpillar grader. The bores first get machined on our Rottler cnc boring & milling machine to make them perfectly round & true. We then weld the bores with our bore welder setup which adds material & [...]
Here’s some pics of a radiator & intercooler stack cooling package we finished up for one of our mining customers. The longer unit on the backside is the radiator. The shorter unit on the front, or engine side, with the long curved upper connections is the CAC (charge air cooler). Both the radiator & the [...]
Here’s some pics of a copper and brass four row radiator we had in for a rod and repair. Both the inlet & outlet tanks were removed. The tubes were rodded out to clear them internally of all fouling & blockage. We then ran both headers which involves melting all the solder off of the [...]
Here’s some pics of a Caterpillar 18M Grader Axle we had in for rebuilding. In these pics the Axle is mounted on our Rottler CNC machine for boring, or machining, all the bores to make them perfectly round as well as give some room for welding. After the bores are round & true we weld [...]
Here’s some before & after pics of an aluminum oil cooler we had in for cleaning & repairing. This cooler is for the compressor on an Epiroc D-65 drill rig. We first steam cleaned the cooler inside & out. It then gets soaked, or boiled, in our ultrasonic. After it's completely clean inside & out [...]
Here's some late night pics of a 793F Cat radiator we’re in the middle of rebuilding. The radiator is a Mesabi with a little under eight hundred individual copper tubes. Once the radiator rebuild is complete & it passes the pressure test we will start installing all the external cooling system components. When we're all [...]

Here’s some pics of an aluminum threaded fitting hose connection we fixed on an oil cooler we had in for repair. The threads on the original threaded bung were cross-threaded with a couple of threads stripped out. We machined a new threaded connection out of a piece of solid round aluminum stock. We then cut [...]
Here’s some before & after pics of a dual aftercoolers assembly with the fan shroud we had in for cleaning & repair. The charge air coolers, or CAC's, are off of an Epiroc D-65 drill rig. These aftercoolers cool the intake air charge of a Caterpillar C27 ACERT Tier 4 Final diesel engine. Both coolers [...]
