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 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 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 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 couple of Caterpillar heavy equipment parts we repaired & rebuilt. On the front of the trailer is a 16M grader axle assembly. On the back of the trailer is a D10T dozer ripper table frame assembly. Extensive machine work was done to both pieces in order to get all [...]
Here are some pics of a couple heavy equipment parts we have in for repair. The flatter rectangle piece is a Caterpillar D10 dozer equalizer bar. The center bore is getting machined until it is perfectly round & properly located in the bar. Then it will be welded up with the bore welder & then [...]
Here are some pics of a couple of Caterpillar grader axle assemblies we rebuilt & delivered back to our customer. The smaller axle is for a 14M Cat grader. The larger axle is for a 16M Cat grader. Both axles were completely stripped down to have all the machined bores & surfaces that had wear [...]
Here are some before & after pics of a Komatsu 830E-5 fuel tank we had in for a quick turn-around. The two larger sidewalls of the tank were blown up & bulged out from excessive pressure inside the tank. When these haul truck fuel tanks come in blown up like this it gets pretty extensive [...]
Here are some pics of a CEM (clean emissions module) we had in for cleaning & reconditioning service. This unit is basically the DPF (diesel particulate filter) for a 789 Caterpillar haul truck. The long rectangle pieces with the round honeycomb type passages is the SCR (selective catalytic reduction) catalysts which is what gets plugged [...]
Here are some pics of a CEM (clean emissions module) for a Caterpillar 789 haul truck we had in for reconditioning. We completely disassembled the module & cleaned every piece inside & out. The heart of the CEM is the SCR Catalyst assembly which is the most critical piece to get clean of all the [...]
