"How should i be loading these into the chuck?"

Load the jaws in the normal sequence, starting with No 1 but skip the one with the missing tooth.

eg. If the first spline on No2 is broken. Rotate the sctroll and engage No 1, then continue to No 2 but as it is broken keep going and engage No 3. When the start of the scroll comes back to No 2 position, you can engage the second spine.

Paul.

Remember too, that the capacity of the chuck has been reduced by the missing tooth so take care it doesn't happen again !

Especially since it is probably No 1 jaw ?

.

Sorry to contradict Paul ... but it appears to be #3 that is damaged

So, load #1 and #2 as normal, then do a full turn before loading #3

... incidentally the next tooth on #3 looks to be bruised, so it may need cleaning-up before it will load.
