Here’s some pics of a couple heavy duty industrial bolt-on radiators we are rebuilding with new cores. The radiator with the crankhole in the core is for a garbage truck. The new radiator core with the blank headers is for a diesel pusher RV motorhome. Recoring both radiators with new heavy duty cores was recommended [...]
We're in the process of rebuilding an 18M Caterpillar Grader Circle & Drawbar assembly. These pics are of the disassembled circle drive motor. The pinion gear is broken, or shattered, into multiple pieces. It's basically grenaded. The splined shaft which mates to & enagaes with the pinion gear has the splines completely stripped & wiped [...]
Here’s some pics of an aluminum charge-air-cooler, or aftercooler, we cleaned & repaired. This cooler is off of an Epiroc Pit Viper drilling rig. The cooler had some damage to it externally as well as some leaks which we fixed by tig welding. The brackets that had worked their way loose were tig welded back [...]
Here’s some pics of a Caterpillar part number 151-5747 Blade Stabilizer. It looks like an A-Frame & it is off of an 834H RTD, or rubber tire dozer. The two bores were badly worn & out-of-round. The inner & outer bores where the shaft rides were both extremely worn & out-of-round as well which allowed [...]
Here’s some pics of a Caterpillar 793F haul truck MESABI Radiator Module Cooling Package we recently reconditioned. This radiator module assembly came in with extensive damage due to the truck it was in colliding into another haul truck. Numerous pieces & parts required many hours of straightening & tweaking to get them back in shape [...]
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 [...]
