A few weeks ago I requested some help on repairing the rear wheel assembly on my John Deere 6620. The right rear wheel dropped into a hole and then the incident succeeded in pulling the round shaft out of the box like framing at the rear of the combine. The round shaft was factory welded into the box and the axle rotated on it. So, my question is if the shaft was welded into the box from the factory would it be OK to fit the shaft back into the box and weld it again without damage to the shaft (weaken the shaft)? Has anyone done this???? Called a junk yard today about getting the entire rear frame and the owner said they sold two of them for 6620's this week alone - $500 each. Another friend's 6620 went down last weekend. This must have been a weak spot for 6600's and 6620's. I still haven't raised the combine yet, so if there are any more good ideas about doing that it would be appreciated. Thanks.
