Here are some before & after pics of a Caterpillar 789C haul truck radiator we had in for a complete overhaul. This one came in with heavy fouling externally on the fins. Most of the build-up was petrified mud that was almost like concrete. We gave each folded core a rod & repair after a [...]
Here are some pics of a Caterpillar 18M Grader Blade Hanger we had in for reconditioning. We mount these blade hangers on our Rottler EM105H multipurpose CNC boring and milling machine as it gives us the versatility we need for these unique machining operations. The bores are first machined in the boring operation to make [...]
Here are some pics of a Caterpillar 789C folded core radiator we had in for a repair & rebuild. The 789C Radiator has fifty eight individual folded radiator cores. Each core received a rod & repair. Before assembly each individual core was pressure tested to make sure they are leak free before final assembly into [...]
Here’s some pics of a Caterpillar D10T2 Dozer Ripper Table being machined on our Rottler EM105H Multipurpose CNC boring & milling machine. The bores were worn out-of-round so we machined the bores with the RAD (right angle drive) to get them perfectly straight & round. We then welded the bores with our bore welding fixture [...]
Here are some pics of a couple of aluminum air & oil coolers we had in for repairing. Both coolers are combination coolers which have a short section of the core that cools air while the larger section of the core cools oil. These coolers are for the compressors on Caterpillar 495, or 7495, shovels. [...]
Here’s a few pics of a Caterpillar 6060 shovel radiator & intercooler cooling stack assembly we picked up for repair & rebuilding. The radiator & intercooler, or CAC, are all aluminum. The radiator mounts piggyback to the intercooler & they stand straight up vertically on the back of the shovel. The shovel has two engines [...]
Here are some pics of a couple of Komatsu 830E-5 haul truck clean emissions modules, or DPF's. These diesel particulate filters came in for cleaning as they were plugged up with soot & carbon build-up. We cut the stainless steel housings open in order to achieve access to the SCR substrates. We then thermal clean [...]
Here are some pics of a Caterpillar 793C Radiator we’re finishing up repairing & rebuilding. This one came in with a couple leaks in the top tank. We ended machining the blocks that the upper hose connections bolt to off the tank so we could remove all the old weld material. We machined new blocks [...]
Here are some pics of a Caterpillar CEM, clean emissions module we cleaned. The CEM is basically a DPF, or diesel particulate filter, like is used on smaller passenger size diesel trucks & vehicles. The ceramic honeycomb type filters are referred to as the SCRs (selective catalytic reduction), DOCs (diesel oxidation catalysts) and they trap [...]
Here are some pics of a Caterpillar 789C haul truck, or dump truck, radiator we’re finishing up the repair & rebuild on. All fifty eight of the individual folded radiator cores received a rod & repair. Each radiator core, or section, was then individually pressure tested before being assembled into the tanks & sideframe assemblies. [...]
