Glad you figureds it out. I went through similar with the 4200XL excavator. I was worried about it at first, but found the task to be not too bad.

I found out something else after replacing the bucket servo , I ran for 50min. and burnt the boom servo out, point being I though it was something I was doing by over loading the bucket servo trying to break out more dirt, I would say now its the cheap servo they use because your not putting that much force on the boom, now the stick yes crowding with the bucket, anyway I'm replacing all with HI TOR.s today.
