Here’s some pics of a Caterpillar 793C haul truck A-Frame rear end diff support that we overhauled. The bolt holes around the hitch pin bore were cracked so that means the entire yoke needed to be replaced. After cutting the cracked yoke out from the legs, or supports, we prepped them for placement of the new yoke. It is an extensive amount of welding with numerous passes to get the new yoke completely welded back in place to the legs.
