Main pulley bolt washer question
 

When taking apart my engine I don't recall there being a separate copper washer underneath the main pulley bolt. I'm gathering the last few pieces needed for my rebuild and I'm trying to figure out if I need a washer or not. Below is my main pulley bolt as it is now:

There appears to be a copper washer staked in place. Is this the washer in question or is there another one that goes on top? I don't recall any instructions to stake the washer in place. I've half-heartedly tried to pry it off with no success.

Yes, that is the copper washer staked in place.
Yes, it'll pry off given enough force.

Mazda recommends to replace it every time you remove it.
In a pinch, we just reanneal the copper washer if you don't have a replacement handy.

Thanks for the clarification. I couldn't find any reference to the washer being staked anywhere. I have no problem replacing it considering it's probably the original that came with the car. Should I hold onto this one to use when checking endplay so I don't crush the new washer prematurely?

If you're going to follow the Mazda procedure to check end-play, then there is no problem reusing the old one to do so.
Yes, it makes sense not to "crush" a new copper washer just for the end-play checking procedure.
