Hi, Caterpillar 13.
Sorry. No go on that one. You can see for yourself here:
http://www.dracoequipment.com/Parts%20Links%20and%20Pages/UNDERCARRIAGE%20DRACO%20VPIHQ1%20Reduced.pdf
This is a downloadable PDF file - - - ALL 759 pages of it. Unless you have real eagle eyes, hit the little + button up at the top to make it easier to read.
Page 92 has the Cat D2 information. Page 338 has the TD6 information.
There is also some ground engaging tools information towards the bottom of the PDF.
Hope this helps.
