Old gears were inline with brass bushings.

Tim Bailey back from the dead post, I just bought the c*****s 50# unit and I think they changed up the gear box. All three gears look solid cast steel like impact tool grade, with enclosed bearings on either side of them. I see no spot welds. I have 5 Phillip head screws holding the box to the unit. Seems the older units have 4 Alan heads holding it on. Any way anyone can confirm this?
