Could anyone post or PM me dimensions or changes that need to be made in order to work with the new model so our team could get started this weekend? |

The primary difference in dimension for us is the hole pattern. In DWG NO. 1 (Chiaphua Plate) from the NBD paper, we replaced the 0.6875" dimension with 0.745" and the 1.055" dimension with 1.110". Since this hole pattern is larger than the DC980 model, the plate needs to have a larger OD. We used 3". The servo plate will need a bit of adjusting as well to accomodate the larger hole pattern.
We do not use the method of boring out the sun gear as described in the NBD Paper, so I cannot speak to any mods needed on the transmisison case. Last year we successfully used the StevenB method of using a "sun gear adaprter" described in this thread:

It worked beautifully for us last year.
Hope this helps you get started. Let me know if you need more info.
