Hi,he was yelling at me. I said I did not appreciate his attitude- at first he told me if I did not like to give it back- I told my step son remove the ott and I told him he could have the machine back- I also told him that is no way to treat a customer- not to mention I have bought over 265 grand worth of equipment off of him directly and I am just a home owner not a contractor- he then apoligized and said he was under alot of stress- any way he got me the parts- as I have stated before I dont trust their service department- any way it turns out the pins were never greased- they were scored and worn- but the bushings were the same inner diameter as the new ones I was given. I did not have time to change the parts yet- I had to put the machine back together because I needed the lift it was on. I greased it up and put it in the barn for now-I will have more time over the weekend to fix it.
