Repair DOG BONE for MINING Truck using Zayer Bed Mill! | Machining & Bore Welding

We’re fixing a critical component for a big mining truck and we’ve got a different approach that might raise some eyebrows! We’ve got a dog bone linkage off a Caterpillar 785 haul truck; the bores are a little worse for wear and need to be reclaimed. We'll be setting the part up on our Zayer bed mill and using our shop made adapter with a Wohlhaupter boring head to machine out the worn bores. Then, to save some serious time, we're keeping the part right where it is and using our Zayer mill's head to setup the line boring mounts ready for welding. Now, here's where things might get interesting. We're using our Sir Meccanica WS2 portable bore welder to weld those bores vertically while they're still on the mill. Some folks might have a different approach, but we're all about efficiency! Once the welding is done, it's back to machining the bores to exact specifications and cutting in the snap ring grooves. We'll then drill in the grease ports, pop those snap rings in, and use our 150-tonne hydraulic press to press in the spherical bearings.
