Dodge has changed their 2-bolt flange bearings (through bore length and recess from inner race to back face of bearing) and unfortunately for us, we have used numerous bearing sizes on numerous assemblies. When the bearing files were created (from Dodge/Baldor) they were brought in as imported bodies and mated as such. Now comes the sticky part. I have used feature recognition in SW to make changes to the bearings, however if these are pushed up into the vault ALL OF THE MATES WILL BE LOST on ALL existing assemblies since surface id's have changed. I have been racking my feeble mind on a way around this without having to re-constrain every bearing mate....AHHHHHH! Suggestions anyone?
