I was told this is a genuine AC Delco reman.
It looks the part, but I am not 100% sure on this. Feel free to verify or what not.
Came off a running engine, but when tested the distributor will not hold vacuum.
Testing w/ both vacuum & low air pressure revealed it's leaking badly from bearing area.
The bearing has no play, but pretty rough, doesn't feel good spinning.
I am going to try and replace the bearing.
See if I can make a good unit out of it.
On with the pics.
Here is the disassembled unit laid out. Was very clean inside, and hardly any wear on cam drive.
Here is how they indexed the rotor to shaft
Here is the Mitsubishu optical sensor, appears to have been reworked/repaired.
Here's the wheel, notice the rub marks. It seems flimsy compared to the other OEM opti wheels I've got from other units. Different # as well.
And last the bad bearing. Nothing comes up with a search on this part# 6903RS. But from research others report bearing #SX0389LUACS25 works.
Anyone else taken a recent AC Delco reman apart?
