I have a 5U series D2 that has a leaking final drive. I thought Iíd tear into it, but Iím having problems getting the track apart. Over the years Iíve had other machines that I have been able to split the track, but Iím having trouble with this one. Iíve found the master link pin (solid pin, not OEM) and have used my home made pin press that uses a 12 ton bottle jack to attempt to press the pin out, but with little success. I heated the links on each end of the pin and was able to move the pin about 1/8Ē, but thatís it. Iíve done more heating and have attempted to push the pin back, but no luck.
My next move is to drill out the center of the pin in an effort to weaken the pin and then push again.
Any other ideas?
