Oil Seal, Lower, X3 Mill CLEARANCE

Installed this on my X3 mill and the lower spindle area is finally staying clean without oil dripping everywhere. The fit was exact, and it took maybe five minutes to swap out the old one.

Finally got my quill assembly back together and this seal fit the bore perfectly, no trimming needed. The rubber feels dense enough that I’m confident it’ll keep the grease in and the dust out for a long time.

Went on without any filing or fuss, which is exactly what I needed for my X3 quill rebuild. The seal fits snugly and should keep the lubricant where it belongs down in the spindle area.
