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 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 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 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 [...]

Here’s some pics of a Hitachi EX5600 shovel radiator we picked up for repairing & rebuilding. This radiator is comprised of a Low-Temp radiator half & a High-Temp radiator half so basically two radiators in one. It is a MESABI with individual radiator tubes rather than a conventional core unit. The radiator is leaking on [...]

Here’s some rebuilding process pics of a Komatsu 930E-5 MESABI Radiator. The 3-Row High-Temp Radiator is about complete. The 2-Row Low-Temp Radiator is ready for the tubes to be installed. The MESABI tubes in this one are all aluminum which are relatively delicate in comparison to their copper counterparts. They are lighter, & they are [...]

Here’s some pics of a cooling package we repaired & rebuilt for an Epiroc Pit Viper 271 Drill Rig. Inside the steel framework are three aluminum oil coolers, an aluminum radiator & two hydraulic driven fans. All three coolers as well as the radiator were cleaned, repaired & pressure tested. The two hydraulic fan motors [...]
