Sure looks like weld material in the pic but being a die maker I can attest to how hard work hardened steel can become. I have had to sometimes hone with milling. I will finally begin my 977k next week. I have a retired Cat mechanic with lots of 977 experience to lead the way. I was going to buy a new D6 but they are a year out and none are available in USA. So it’s 977 time…. Wouldn’t mind a pull of that sandwich there mate.Yesterday finished off the line boring on the bucket clam pivot points, the last one broke a few inserts as the cast steel piece seemed to have some nasty hard pieces in there, not sure if it’s been built up with weld in the past.
Have found some pins to suit so will machine these down to suit the bore diameter then that will give me the internal diameter of the bushings I need for the back of the bucket where it attaches. Still got a way to go but felt good to get all the boring gear cut off. A good day, cheers
