I'm not sure where the right place to post this would be, but here goes.
I bought this DW745 Type 2 saw off of Facebook Marketplace. I think it was abused. I replaced both of the elevating shafts (5140100-04 Diagram # 82 & 5140100-05 Diagram # 84). I also had to replace both of the bevel gears (5140061-65 Diagram # 56).
The aluminum housing seems to be okay and the lifting shafts move in and out without much resistance. I'm still getting this chunky movement when I raise and lower the blade.
I'm looking for advice before I go though the whole process of replacing the entire aluminum housing (Gear Case A25607 Diagram # 213) on the motor.
Are those gears meshing properly when you spin the handle? It sounds like they're skipping, and just from the brief part in the video it looks like the blade isn't raising steadily.
I don't think they are skipping. It gets smoother when I have the saw on it's side.
