No reason you couldn't add carrier rollers and not that hard to do once you have the parts.
I,m sure if you,d check with a local auto or truck repair shop they could guide you to a shop that does generator work.
SJ, I'll call around this week and see if I can find a shop. First, I need to get the hydraulic hoses replaced so I can get the "Kitty" out of the hole it is in and back to the barn so I can work on it.
