Pulled this thrust plate out of a core motor a little while back:



Yeah, needless to say the rest front assembly was less than stellar.

hhmm...that will make youre day

Wow, that is unusual. That's the Thrust Washer, BTW. The Thrust Plate is the piece that bolts to the stationary gear. Those will blow up like that if they are heated up from bad endplay, bad thrust bearings or sometimes -- believe it or not -- from a nuclear pressure plate. But damage like that the thrust washer is unusual.

I actually looked up the name for the part, because I never really bothered to learn its proper name. The FSM calls it "Thrust Plate", and the plate that bolt to the stationary gear is referred to as a "Plate". The "Thrust Washer", per the FSM, is the piece just behind the counterweight.

S4 FSM, Chapter 1 Engine, Pg 1-31

But yeah, thrust washer sounds better.

Okay, good point...but it's called a thrust washer in daily practice.

I've called it "the first piece" for quite some time...

Did you have any Oil feed Problems?

That must have been an End Play Problem?? If that was oil would'nt the Eshaft bearing fail first?

This wasn't my own engine, it was a core that was sent to us (rx7store).

It appears that someone took the front pulley off and the torrington bearings shifted. Put it all back together, and ran the engine for quite a while.

The stationary gear and rotor bearings were fine.

Yep, seen it before.
Dropped the Torrington bearing, and the eshaft wants to shoot out the front cover.
This usually eats the front stat gear bearing too though, right?

Actually all the bearings were fine, but the front rotor really really didn't want to come off the e-shaft. But even that bearing wasn't spun.
