Not sure if this qualifies as bad as the others, but...
Back in my rookie days, I had a D4 or 6? that was loaned to me through my BIL. First time for me with a track machine. I was doing site work at my new house and figured this thing could help remove some rocks that were poking out of the ground in the future lawn area. So off I went, pushing and digging(yep, with a dozer) and had one rock that did move, but I couldn't get it out. Before I realized what I did, I had dug a mote around this rock that was about 5' deep. This 'little' spud turned out to be one huge potatoe, but since the dozer could move it back and forth, I kept at it.
Next thing I know...CLANK...the track broke. One of the pins snapped. So here I sit, knowing nothing about this machine that was stuck in a big hole. I was worried that the owner of it would not be a happy camper, so I tried to fix it. I used a couple of cumalongs to bring the track back in place and try to reconnect it. Turns out the master pin broke. I got it to within an inch or so of reconnecting, and then the cumalongs broke!! Now what do I do?? I had a buddy that wrenches on these rigs, so I called him. He couldnt stop laughing after I told him what happened and what I tried to do. I felt pretty stupid after he told me that all that I needed to do was remove a plug, which would have released the grease for the slack adjuster. I was able to reconnect the track finally, but had to travel about 2 hrs away to find a grade 8 bolt big enough to fit.
The sad part, I blew almost 2 days on this rock and fixing the track. As it turns out, the rock was HUGE!! I ended up using a 580 extend-a-hoe to dig next to it and bury it deeper. /forums/images/graemlins/blush.gif /forums/images/graemlins/crazy.gif
