I guess I backed into too many trees because I have two bent axles on my disc. Today I decided to take it apart and straighten out the axles. I got my impact gun and took out the bolts holding the bearing carries for both rear gangs and lifted the 3PH up and neither gang fell. Looked under the bracket and the previous owner had welded all the bearing carriers to the gang support tubing. So first I tried to grind out the weld and got one on the inside but couldn't reach the other 3 welds even with a 9" blade, it was time to break out the oxy torch. I got one gang cut loose and decided it was time to disassemble it. I got all the parts off till I got to the bend and then the spacer spool wouldn't go by the bend. Well I did a little hammering on it and sure enough I was able to get it off, but it broke the end off the spacer (cast iron you know). I said what the heck, see if it will weld back. I put a bevel on one side and stuck both pieces back on the axle to assure alignment and put 2 passes of 7018 on it. It had a little magnetic arc blow and welded a little like metal with dirt on top of it, but it stuck together. I have it soaking in my 350F rod oven for a few hours then I will put it on the outside edge just in case it breaks, it will be easier to take off.
While I had it all apart, I looked at the bearing holders and all of them had at least one side torn about half way out. This is the little 1/16" thick plate with 4 bolts that holds the sealed bearings in the carrier. I got them all straightened and welded up the broken spot plus the rest of it. Each one has a pressure mark that is a slight scribe line where the press tool left a line around it when they put the lip on it. All of them break right in that press mark. The bearing are old old, so while I had it apart, I took my little needle bearing greaser and put in about 10 shots of grease in each bearing. I drilled a 1/16" hole in the steel seal, and pumped grease till it came out around the seal, rolled it several rounds and pumped more grease. It should be better than new now. I know it has more grease than new. Now to get it all back together then tackle the other gang.
Taking a lunch break now.
It will take me an hour to put away all the tools when finished. Two impact guns, 1/2 and3/4" drive, cutting torch, welding leads, drill, 2 extension cord, a 9" grinder, 4.5" with brush, 4.5 with grinder, drill motor, bits, 16#sledge, 4# shop hammer, pliers, chipping hammer, air chipping gun to remove the tab from axle nut, 3/4" combo wrench for backup on the carrier bolts, and a couple grease guns that I can think of off top of my head.
