Here are some pics of a Cat 793C Radiator we delivered back to one of the mines. The radiator was given a complete overhaul along with some welding repairs to the top & bottom tanks. We ended up fortunate enough to have the mechanics swap the radiator we rebuilt with the old radiator they removed [...]
Here are some pics of a Komatsu 930E-5 haul truck radiator we’re rebuilding. This radiator is comprised of Mesabi's aluminum tubes. These pics are all of the HTC (high temp circuit) radiator half. Each tube has been steam cleaned, soaked in our ultrasonic, & then both ends buffed to a polished finish for installation into [...]
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 radiator we picked up from one of our mining customers for a Caterpillar 789C haul truck. The radiator is leaking as well as several of the radiator core sections are loose between the tanks with excessive endplay. The radiator is in for a complete reconditioning overhaul. We'll post more [...]
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 Caterpillar 793C radiator we have in for a quick turn-around. We picked the radiator up from the mine one day & got it completely disassembled & in the full rebuild process the next morning. This one has a lot of solder bloom & internal corrosion. Several cores have internal [...]
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 [...]
Here are some pics of some heavy duty bushings we machined from some solid bar stock material. We have a ripper table for a Caterpillar D10T dozer in for repair and machining that the bores were extremely worn on. We elected to machine the bores until they were true & perfectly round. After we got [...]
Here are some pics of a Caterpillar 994K Hardnose Cooling Package we had in for a PX exchange rebuild. This one was in pretty rough shape. After numerous hours of cleaning & performing multiple repairs we got it all back up to snuff. Every bolt hole has been repaired if needed while every other threaded [...]
Here are some pics of a 6.7 liter Cummins diesel cylinder head we had in for rebuilding. We first disassembled the head so we could thermal clean it in our oven. After baking in the oven we shotblasted the head to bring it back to raw cast iron inside & out. We then magnafluxed the [...]
