This is a radiator module we rebuilt for a Komatsu 930E-5 haul truck. The radiator is a MESABI which utilizes aluminum tubes, or cores. The radiator was leaking due to a cracked tube. External fouling with dirt & rocks was substantial within the tubes & fins of the lower section of the radiator. We replaced [...]
Here’s some pics of an aluminum bar-and-plate heat exchanger that came in leaking. It's an oil cooler for an Epiroc drill rig drilling machine. There was a crack in one of the welds where the tank is welded to the core. We ground down the weld area at the crack & prepped the crack for [...]
Here’s some pics of a Caterpillar 834H RTD (Rubber Tire Dozer) cooling package we delivered back to one of the mines after we gave it a complete rebuilding service. The hardnose, or nosecone, contains AMOCS type radiator sections (cores), an oil cooler, the aftercooler, hydraulic fan motor, fan blade & electrical wiring harnesses. We completely [...]
Here’s some pics of a Caterpillar 18M Grader Axle we have in for a complete rebuild overhaul. The Axle is mounted to our Rottler CNC machine which we have programs written for each of these parts that we machine & rebuild on a regular basis. All the bores are first machined, or bored, perfectly round [...]
Here’s some pics of a Caterpillar 789D haul truck radiator we rebuilt & delivered back to the mine site. This radiator has the Cat folded cores, or sections, which each need to be rodded & repaired. This one came in with some severe damage due to the fan coming off & flying into it. It [...]
Here’s some pics of a Caterpillar 18M Grader Front End Axle & a pair of hydraulic steering cylinders we delivered back to one of our mining customers. We did a complete rebuild to the grader axle as well as the hydraulic steering cylinders. All the pieces & parts were disassembled, cleaned, checked for cracks & [...]
Here’s some pics of a hardnose cooling package we picked up for a Caterpillar 834H RTD (Rubber Tire Dozer) for repair & rebuilding. Inside the hardnose are radiator core sections which are of the AMOCS modular cooling system configuration. Along with the radiator cores / sections is a modular oil cooler, aluminum aftercooler & the [...]
Here’s some pics of a Caterpillar 789D folded core radiator we picked up for a complete repair rebuild. This one has taken a hit from the fan so it has some heavily damaged cores. Some of the steel pieces & parts have taken a beating as well. We'll get it apart & see what all [...]
Here’s some pics of a couple dogbones we reconditioned. The links, or dogbones, are for Komatsu 830E haul trucks. One of them is for the older 830E-1 truck & the other one is for a newer 830E-5 truck. We removed the spherical bearings & removed all the paint so we could magnaflux them for cracks. [...]
Here’s some pics of a Caterpillar 793F haul truck radiator module cooling package we delivered back to one of our mining customers. The radiator itself is a MESABI with individual copper finned radiator tubes which we completely reconditioned. Mounted on & around the radiator are a multitude of other cooling system components such as two [...]
