Does anyone know if there is supposed to be any backlash at all? We were debating on whether or not it should be moving slightly.
Special washer ? If these are the type of blocks I'm thinking of there should be a part #4 as shown in the included jpeg.
The chinesium version of these blocks can have a small amount of backlash. On one sloppy block I resorted to a thin shim in-between the outer races. Not remotely as sloppy as shown in your video.
edit/ Where the thin shim mentioned is place depends on the reason for the slop.
Anyone who says "It only goes together one way" has no imagination.
