Here are some pics of a MESABI radiator for a Komatsu 930E-5 haul truck we are rebuilding. This radiator has the less than desirable aluminum tubes in it. We prefer & recommend copper tubes as they are much more robust. The radiator came in leaking from a crack in one of the aluminum tubes. [...]
Here are some pics of a couple of hydraulic cylinders we rebuilt. Both cylinders were extensively worn & damaged. The one cylinder had bad scoring in the bore as the shaft was bent. The pistons & seals were also badly worn in both cylinders. New gland nuts, pistons & rod ends were fabricated & [...]
Here are some pics of a Caterpillar 6060 shovel intercooler, or aftercooler, and radiator we have in for repair & rebuilding. Both the CAC, or intercooler, and the radiator are constructed of all aluminum. The intercooler had multiple cracked tubes so we are recoring it with a new heavy core with extruded tubes. We [...]
Here are some before, during & after pics of a Caterpillar 793F haul truck fuel tank we repaired & rebuilt. The tank came in due to a major diesel fuel leak. We ended up replacing the entire side wall as it was so badly pitted & corroded that it was extremely thin & lost [...]
Here are some pics of a Hitachi EX5600-6 Shovel Radiator we're in the process of rebuilding. The low-temp radiator half is all cleaned, painted, all new rubber grommet seals installed & the reconditioned tubes are getting installed. The high-temp radiator or HTC (high temperature cooler, or circuit) half will get underway after we get [...]
Here are some before & after pics of a 988 Caterpillar loader radiator we overhauled. The radiator came in for an overheating issue as well as a leak. We completely disassembled the radiator so we could rod out all of the canted tubes in the radiator core. The tanks & side braces got thermal [...]
Here are some pics of a pivot eye, or nosecone, off of a Komatsu 830E haul truck. We get these pivot eyes in with the bores worn & out-of-round. Komatsu doesn't allow any welding to this part but they do offer an oversize bearing carrier. We set these up on our Rottler CNC boring [...]
Here are some pics of a couple aluminum oil coolers we repaired. Both the compressor oil cooler as well as the hydraulic oil cooler were leaking in multiple areas. After getting the coolers internally flushed & thoroughly cleaned we prepped them for welding. After the leak areas were tig welded we pressure tested them [...]
Here are some pics of a Caterpillar 793C haul truck rear axle a-frame support we repaired. The bore in the end of the A-Frame Support was worn & cracked into the bolt holes. Since machining & welding the hitch pin bore was out of the question we air arced (Air Carbon Arc Gouging) the [...]
Here are some pics of a copper and brass radiator that came in for rebuilding. We recommended recoring the radiator with a new heavy duty core. Our customer agreed & gave us the approval. The radiator is out of a good size tug which is used for moving large jumbo jet airplanes as well [...]
