Detroit Locker chipped tooth on splined coupler. Still good to buy?

[Superthermal]

Looking to purchase a used Detroit 5Ton locker out of a 900 series for my M813. The locker has a single half broken tooth. Still good to buy? I dont see any other damage to the adjacent teeth. From the exploded view it appears the collar shares the load with all the teeth simotaniously and one missing tooth may not be that big of a deal. From the last pic below either the machineing was poor or the tooth was improperly machined. or is this gear actually broken and pressed outward?

I would pass on that. Its too much work to install for marginal parts.

If you do go for, it take a grinder and spoon out the damaged areas so there are no sharp edges. Consider doing a dye pen check to make sure no other teeth are cracked.

Swapped in two new Detroit lockers into the rears and am doing the third this week on the front. I am with you, that was a lot of work to put in something that may let go. Who knows maybe it would have been OK.
Either way, I did pass.
In researching this issue though, I talked with the very knowledgeable owner of Gearheart Engineering who makes custom shafts etc.. for the 5 tons. His explanation was that when you brake an axle shaft and the rebound happens with the 1/16 or so rotation slop of the locker the shock of that unloading of tension is what chips and breaks the teeth on the Detroit.
