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. [...]
Here’s some pics of a Caterpillar 789C haul truck radiator we picked up for a complete overhaul. The radiator is comprised of fifty eight individual folded radiator cores. A handful of the cores are leaking in the solder joints so we will be removing the brass tanks from both ends of each core. Each core [...]
Here are some pics of a DPF (diesel particulate filter) off of a Komatsu HM400 that we had in here for cleaning. The SCR (selective catalyst reduction) gets plugged up with soot on today's diesel engines with a CEM (clean emissions module) which causes the engine to run with reduced power. The system can only [...]
Here’s some pics of a Caterpillar 789C haul truck folded core radiator we repaired. The radiator came in leaking due to some folded cores leaking at the solder joints. Each individual folded radiator core received a rod & repair & pressure test before being assemble into the tanks & frame assembly. The radiator is now [...]
Here are some pics of a CEM (clean emissions module) we cleaned. This is off of a Caterpillar 789 haul truck. The DPF (diesel particulate filter) gets plugged with soot which results in reduced engine power. Also part of the system is the SCR (selective catalyst reduction). Cleaning the SCR Catalyst, or DPF filter, of [...]
Here are some pics of a Komatsu 930E-5 haul truck radiator we overhauled. The radiator is a Mesabi with all aluminum tubes. The radiator came in leaking due to some damaged tubes from the center support bar bolts breaking which allowed the bar to contact some tubes. The leak was coming from the damaged tubes [...]
