Guys, I have a D5 Cat that came in today for various welding and I have run into a snag. The equalizer that runs from track to track, under the belly, and holds up the front of the tractor has some serious wear!! I ran a spark test and it looks like it could be spring steel. I called the local Cat dealer which I have never known to be real knowledgeable on welding, and they said, "just build it up with some rods. It'll be fine" I have replaced several of the mounts but never had a bar with this much wear. I talked to one other guy who does alot of dozier repair, and said the same thing. I am just concerned that if I heat this thing up and it loses its strength, then someone is in for a heck of a ride if it breaks and the nose of that crawler hits the dirt. I was thinking about taking some 7018 building up and grinding back to size and it would probably be ok. I even talked to the owner about my thoughts, and he said, "Weld it, if it doesn't work then I buy a bar. I buy it now, or buy it later, so let's try it", but I thought I would ask on here before I started. Maybe some of you guys have run across this before. I have a couple more days worth of welding to do before i get to this anyway. Thanks in advance ~JacksonI didn't want to disappoint zap so i threw the dime in the last pic.....Last edited by MicroZone; 05-22-2007 at 10:47 PM.I'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man......
Reply:Not uncommon..7018 is the rod of choice..Go for it.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:I just welded one up a couple of weeks ago. So far so good. It hasn't snapped, to my knowledge. I'm not sure those are spring steel. Especially if the owner is okay with it I would weld it. I welded the one I did with 7018 also.
Reply:Thanks for the info, That was my thinking also but I wanted to cover my butt. ~JacksonI'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man......

Reply:If this is the #1 leaf (lowest) then it is part# 8M6617. This part retails for $697.72 out in AZ, so try not to put too much time into the repair. To be safe you should pre-heat the material before welding & 7018 rod will be fine.Skip
Reply:red, its the ONLY leaf. its not multiples, just the single bar that runs across. I built new mounts today and built it up. Gonna try to get it put back in tommorrow. Thanks for the info guys... ~JacksonI'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man...... |
