Use the same threaded rod with a smaller diameter sleeve to pull the spindle back into place. I have broken more than one gear, usually from grabbing a high rake tool while cutting Delrin. This one pops out of high gear while under a load.
The new steel gears have sharp edges and need to be de-burred before installation. I used needle files and fine sandpaper to ease the corners. The faces of the teeth were very smooth so I don't think they add to the wear. Not having to pull the spindle offsets any slight accelerated wear IMHO.
