Here’s some pics of a Caterpillar 793D haul truck Mesabi Radiator module we're in the process of rebuilding. The tanks & side frames assembly have been cleaned, prepped & painted. The bores were then wire brushed clean, checked for any wear & size before the new rubber grommet seals were installed. The next step is [...]
Here’s some pics of a Caterpillar Grader Axle on our Rottler Multipurpose CNC boring & milling machine. The surfaces on each side of the center support bore were badly worn so we welded them up & then machined them flat, square & back to the correct thickness spec. The surfaces that retain the lean arms [...]
Here's some pics of a Caterpillar 793C mining haul truck radiator we picked up for repairing and rebuilding. We'll post more pics of this one after we get it all done. 5435 Desert Point Dr. Las Vegas, Nv. 89118 Ph: (702) 649-2366 or (702) 649-0648 Fax: (702) 649-4133 www.MotorMission.com Facebook.com/MotorMission
Here are some before & after pics of an industrial 2-step flywheel we surfaced. The flywheel is off of a Kenworth semi truck with a manual transmission. We first machine the larger lower surface on our Winona Flywheel Grinding machine & measure how much material is removed. We then setup on the narrower upper surface [...]
Here’s a load we delivered back to one of our mining customers. On the front of the trailer is a Caterpillar 16G grader circle & drawbar assembly. Behind the grader circle is a 16G grader axle assembly. Both pieces were completely disassembled, repaired & machined back to new OE specs & then reassembled with all [...]
Here's some pics of a Caterpillar OE plastic aluminum radiator & aftercooler cac for a 430F backhoe. Our customer asked us to build them a new radiator as a replacement wasn't available. We fabricated some metal tanks to replace the original plastic tanks & soldered them to a new heavy duty copper brass radiator core. [...]
Here's some pics of a Caterpillar Grader circle drive motor we’re rebuilding. The pinion gear, brass gear & worn drive gears were all worn requiring their replacement. The clutch assembly was pretty well hammered as well. We had to heat the housing to remove the bearing races as they were spun & fused in place. [...]
Here’s some Caterpillar folded radiator cores on the rack going through our rod & repair rebuilding process. The short cores are for 793C haul truck radiators as well as some grader radiator variants. The longer cores are for the 785B haul truck radiators as well as some genset radiator variants. 5435 Desert Point Dr. Las [...]
Here's some before & after pics of an older copper brass radiator we recored. The radiator is off of a Ford Skidsteer Tractor. The radiator came in with a flat, or continued, fin core which was plugged pretty hard within the fins externally. We ended up recoring the radiator with a high efficiency serpentine core. [...]
Here's some pics of a Mesabi high temp & low temp radiator tanks & side frame assembly we're rebuilding. The radiator is for a Komatsu 830E AC haul truck. In these pics all the individual Mesabi tubes are removed & we have the tanks & side frames cleaned, repaired, prepped, painted & detailed. The next [...]
