New Echo CS590, can't get e-clip back on

[greyeyezz]

I was checking out my new Echo 590, pulled the clutch drum off, now I can't get the e clip back on. There isn't enough room to access the groove unless I apply a ton of force to the drum then it's impossible to snap the clip on one handed. There has to be an easier way, I've done this a hundred times with my Stihl's. Thanks, help the noob, LOL.

Never mind, that drum has to be rotated just right to snap into place, I got it.
