Cracked Welds - Your advise to repair?
Got an 1845C that is used for light use around the place. Bought it used a couple yrs ago, I never noticed that the welds at the main pivot point on both sides are cracked (see picture). What kind of steel did they use on these, for purposes of welding up? Not that it really matters, but is this a common problem?
Hammers really make this happen. Every one of the 6 at work have been broken many times. Vee out as best you can and weld with 7018. They are a tough machine!

if you drill a hole like a 1/4 inch drill bit size a half inch past the crack on either end then grind out and weld with 7018 or whatever rod your comfortable with or a decent size mig gun. if you try to weld with something your not comfortable with you wont be helping yourself any.
Thanks guys for the suggestions. I can V out the crack and weld with either arc or wire-feed. But let me ask you this: this unit has about 5000 hrs on it. It seems pretty tight still, but I'm wondering if this is the time to pull the pins and check for wear ....and possibly replace the bushings?

Does the loader or bucket wobble or shakes as you operate it? If not leave it alone. Unless you feel
