Here are some pics of a radiator out of an MTU DS3250 standby auxiliary generator. The mechanics determined that the radiator was leaking so we lined up our schedule with the crane so the radiator could be set on our trailer as soon as it was lifted out of the enclosure. The radiator consists [...]
Here are some random pressure testing pics of various aluminum oil coolers, heat exchangers & aftercoolers we were repairing & finalizing to finish off this week. The larger aluminum cooler in the test tank is an aftercooler, or charge air cooler, for a Caterpillar 789D haul truck. The smaller black coolers are bar-and-plate aluminum [...]
Here are some before & after pics of a hydraulic jack cylinder we rebuilt. This hydraulic cylinder is off of an Epiroc Pit Viper Drill Rig. The cylinder came in for rebuilding because it was leaking. The seals were worn along with some of the other internal pieces & parts. Once the internal parts [...]
Here’s some pics of a couple of Caterpillar mining equipment radiator cooling system packages we rebuilt & delivered back. The gray radiator on the orange stand is for a Caterpillar 6060 shovel. The cooling stack consists of an aluminum radiator & intercooler. We cut the tanks off both the radiator & the cooler, machined all [...]
Here are some pics of an aluminum inline six cylinder Toyota 2JZ cylinder head that we did a three angle valve job & surface to. We painted the valve seats with some blue Dykem before machining them so we could better see when they were cleaned up. A closer look at some of the pics [...]
Here are some pics of an aluminum bar-and-plate radiator for a Caterpillar D10T2 dozer. The radiator came in heavily plugged externally along with a leak. We steam cleaned the radiator inside & out before soaking it in our ultrasonic cleaning tank. After we got it all clean inside & out we pressure tested it to [...]
Here are some before, during & after pics of a radiator hardnose cooling package we rebuilt for a Caterpillar 834H wheel dozer. The Caterpillar modular AMOCS Radiator cores, or sections, were all constructed of brass. After cleaning & pressure testing all ten cores we ended up finding leaks in the tanks of three of them. [...]
Here’s some pics of a couple aluminum pulleys we custom machined for a customer's hotrod. We machined the old pulleys for this customer in the past but he's making some changes which requires different pulleys. The crank pulley is machined with both v-grooves as well as serpentine grooves. The v-grooves drive accessories & the serpentine [...]
Here are some pics of a radiator hardnose & a-frame blade stabilizer we rebuilt for a Caterpillar 834H wheel dozer. The blade stabilizer had worn bores which required boring, welding & machining to get them perfectly round & back size for the new pins. The hardnose contains the radiator, aftercooler, oil cooler & miscellaneous other [...]
Here are some pics of a Cummins ISB 6.7 liter diesel engine block we had in for machining. The cylinders had some scratches & wear so we bored them oversize by .020 (twenty thousandths). The deck surface had some imperfections so we machined, or surfaced, the top of the block flat & square. We then [...]
