I recently took my impeller off to send to impros and put in a new wear ring. I noticed the circlip had seen better days so I took it off as well as the oil seal below it. Unless it was fused together which I doubt, I didn't see the spacer that's in the diagram below:

So this what I see after taking off the clip and oil seal:

The part I should be looking at is the other seal but pictures online of it don't show this metal ring around it that is acting like a spacer. Appears to be attached. I can only fit the rubber oil seal and the circlip. Here's more pics to prove:

Here is the spacer, sits flush and there's no way you can add the seal and clip on top.
So what the heck is this? Should I just not put the spacer in and continue on? Don't want any water intrusion or any issues due to this not matching the diagram 100%. What do you guys think?
