Here’s some pics of a large aluminum charge air cooler we recored for a Caterpillar 6060 Hydraulic Shovel. The intercooler is so large that it is made up of four individual bar-and-plate cores which are all tig welded together to make one complete unit. We recore a fair amount of aluminum coolers for both liquid [...]
Here’s some pics of a set of 4.0 Ford V6 aluminum cylinder heads we had in for machining. The surfaces of both heads were warped which called for milling the decks, or surfaces, for mating to some new head gaskets. Each head ended up requiring seventeen thousands (.017) of material removal from their surfaces in [...]
Here’s some pics of a Komatsu 830E AC haul truck radiator we picked up for rebuilding. This radiator is a Mesabi with well over a thousand individual radiator tubes. Each tube will be removed for cleaning, inspection & reconditioning if they pass all the criteria for reuse. We'll post more info & pictures on this [...]
Here’s some before & after pics of a John Deere diesel cylinder head we reconditioned. The head is off of a 6101A inline six cylinder engine that powers a 744E loader. One of the intake valves as well as one of the exhaust valves were damaged & needed to be replaced. All the other valves [...]
Here’s some pics of a bunch of Mesabi radiator tubes we're in the process of reconditioning. Some of the Mesabi radiators we get in for rebuilding have aluminum tubes while some of them have copper tubes. We prefer, and highly recommend, the copper tubes as they are much more robust than their aluminum counterparts. Aluminum [...]
Here’s some pics of a Caterpillar 140M Grader Circle we have in for repair & reconditioning. The surfaces that the guide shoes & shims interface with are worn & scored. The surfaces are first machined & then welded up. After all the surfaces are built back up after welding the circle is mounted back on [...]
Here’s some pics of a Komatsu 930E-5 haul truck radiator we picked up for repair & remanufacturing. The radiator is a Mesabi unit with all aluminum tubes. We are removing all the tubes for cleaning & reconditioning as well as replacing all the upper & lower rubber grommet seals. There are some damaged tubes that [...]
Here’s some pics of a Caterpillar 16M Grader Circle we're in the middle of repairing & rebuilding. The teeth that the pinion gear engage with to spin, or turn, the circle & blade come in worn & damaged. We cut the bad sections of teeth out & weld in new segments which are sections of [...]
Here’s some pics of a Caterpillar D10T2 dozer radiator we had in for a complete rebuild overhaul. The radiator is a Modine CGT, copper grommeted tube, unit which had seen better days. There were fifty tubes that were worn very thin from debris being thrown at them by the fan. All the other individual copper [...]
Here’s some pics of a delivery we made to a couple of our mining customers. The yellow radiator is for a Caterpillar 793C haul truck. The radiator we brought in was a folded core radiator & our customer requested us to change it to a Mesabi radiator. So this radiator is a new unit with [...]
