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 [...]
Here are some pics of a Komatsu 930E-5 MESABI Radiator we picked up for an overhaul. The radiator is leaking so we'll need to separate the high-temp & low-temp radiator halves so we can locate the leak before removing all the tubes. This radiator has MESABI aluminum tubes with aluminum fins which are a [...]
Here are some pics of a Caterpillar 18M grader circle, drawbar (A-Frame), drive motor & blade hanger we did a complete repair & overhaul to. All the bores were machined, welded & bored back to the OE specs for new bushings & pins. The teeth on the backside of the circle were worn so [...]
Here are some before, during & after pics of a Caterpillar 994F loader radiator we rebuilt for one of our open pit mining customers. This radiator is a MESABI with a little under a thousand individual radiator tubes. The lower left corner of the bottom tank was cracked & had been previously welded. After [...]
Here are some before, during & after pics of an old cast iron Hercules water pump we rebuilt. Antique & obsolete water pumps come in for repair & reconditioning quite often. We completely disassemble the pumps & blast all the parts down to the raw base metal. Most of the time the shafts are [...]
