Here’s some pics of some Mesabi Radiators we have in the shop right now. Two of the radiators are for Caterpillar 793F haul trucks. The taller radiator is for a LeTourneau L1850 loader. These three radiators have nearly three thousand individual Mesabi tubes that we are cleaning & reconditioning. Three thousand tubes equates to nearly [...]
Here’s some pics of some front end parts we have in for repair & rebuilding for a Caterpillar 16M Grader axle. In these pics we are assembling the lean arms & spindle housings with new bearings, races, bushings & seals. After they're assembled we will install them into the axle beam assembly. 5435 Desert Point [...]
Here’s some pics of a heat exchanger we delivered back to the mill at one of the mines. The unit came in with the tanks & tubes in the core bulged & blown up like a balloon from an over pressure condition. We ended up replacing the core & fabricating new tanks to complete the [...]
Here's some pics of a Caterpillar 793C mining haul truck radiator we rebuilt. All sixty of the individual folded radiator cores were disassembled & given a rod & repair. Each core was individually pressure tested before being assembled into the tanks & side frames. After the radiator is completely assembled it is pressure tested as [...]
Here’s some pics of a Caterpillar 16G grader spindle housing we're in the process of repairing & rebuilding. The upper & lower counterbore surfaces are worn & damaged from severe metal-to-metal contact with the lean arms. We start with machining the worn surfaces & then building them up with welding filler material to match the [...]
Here’s some pics of a Caterpillar D10T hardnose cooling package we rebuilt. We disassembled the entire nosecone assembly down to the bare grill guard housing. The hardnose had some cracks which we prepped & welded. The radiator that mounts inside the nosecone is a Mesabi type which got completely rebuilt & pressure tested. Both aftercoolers [...]
Here’s some pics of a Caterpillar 16M Grader Circle & Drawbar assembly with the circle drive motor & the moldboard. We completely disassembled it so each piece could be blasted, checked for cracks, inspected, welded, machined & repaired. After all the welding & machining was completed we assembled the complete unit with all new wear [...]
Here’s a few pics of an all metal copper & brass radiator we are rebuilding. In these pics one of our radiator technicians is melting the solder off of the header plate at the tube-to-header joints. This is what we call running the headers. After all the old solder is removed & the area is [...]
Here’s some pics of a Mopar crankshaft & harmonic balancer for a supercharged engine. In order to strengthen the balancer on the snout of the crankshaft for the extra pressure from driving the blower an extra keyway & woodruff key are needed. To do this we machine a slot in the snout of the crank [...]
Here’s some pics of some aluminum oil coolers & a radiator for a mining drill rig we completed. All of the units received a thorough cleaning internally & externally. After pressure testing to see where they were leaking we proceeded with the appropriate repairs. After final pressure testing to ensure they all have no leaks [...]
