My S600 motors on my Emaxx are in same situation, caused by motor shaft being shorter than the Titans they are replacing. I was concerned like you that pinion would come off after running a while. I am barely on the edge of the shaft and use a flat spot and blue loctite. About 2 dozen runs later, nothing has come off and I've stopped worrying about it.
I use motor spray to clean both set screw and the set screw hole before applying blue loctite. Any trace of oil on either - loctite will either not set at all or only develop part of its full strength. Also have to give it some time to set.
