The spindle comes out of the right/chuck/tailstock end.
The back gears will probably run with one broken tooth but you won't be doing the mating back gear any favors.
As the gear is cast iron rather than Zamak which it is in the somewhat similar Atlas machines, it can probably be fixed if you have or can get access to the appropriate welding equipment and gear hob. But whether that will be cheaper rather than more expensive depends upon a bunch of variables. I would personally first look for a used replacement. According to the 4800 manual, the part number changed from Gear DL-220 to Gear Assembly DL-220S at serial number 16673. However, the parts of the assembly probably consist of the DL-220 Gear plus the direct drive pin and detent components. Which may have been the only way they sold it to begin with. We do have the Clausing drawing of DL-220 gear. Which you will need if you try to repair it as it gives the gear tooth details.
The machine model number before the Atlas purchase was 100 Mk 3. It's parts list gives the bull gear part number as DL-218. So the two may not be interchangeable. You will need to call Clausing and ask before you start looking for a used replacement.
