Hello all. I picked a BC108 as a means to get some family members into my house for the coming holidays. I ran it up and down a couple of times previously, but yesterday I noticed it was not going up. The large threaded rod is turning but the platform won't raise. It goes down without issue. I look at the back and I see this slotted bearing moving freely on the turning shaft (screenshot). Am I correct that the bearing needs to be pushed down the shaft a bit so it's groove is situated where the weld beed is located? Any help is appreciated. --Rick
