Eccentric shaft differences
#1
Just curious if eccentric shafts between generations and AT/MT are the same or different?
I'd imagine the eccentric shaft between 2nd gen and 3rd gen may be interchangeable.
The eccentric shaft I recently acquired has a smaller diameter tapered hole where the pilot bearing is installed. I checked some S5, S4, and FD eccentric shafts and all of the parts I tested can fit the S4 pilot bearing I'm using.
Just wondering if I should bore out this eccentric shaft since the motor is closed up or if I should rebuild again with a different eccentric shaft.

I removed the previous pilot bearing. Perhaps the previous one was installed into a failed pilot bearing (as you mentioned).
It's just the first time I've ever encountered an issue with the pilot bearing not fitting.
The other S5 eccentric shaft in my garage had a bearing failure so I cannot re-use it.
Maybe it's safer that I rebuilt the engine with a new eccentric shaft just to be safe.
I'm hoping to hear some feedback from engine builders that may have seen a damaged e-shaft or something similar to what I'm seeing.
Sounds like the outer race is still in the eshaft, not letting the new bearing slide in.
