Rotor Wear Acceptable?
 
Bought a car with an engine which was thought to be a blown. Pulling it apart the front stationary bearing was actually the issue. Now the shaft I can't really use due to the journal wear. The housings and irons don't look too bad either. The rotor on the other hand have some face wear which was new to me. I will attach some pics but measure with a pair of calipers (gauge blocked accurate as I don't have 3-4 mics) I'm finding the worst of the wear I would call 3.1315. Wondering if I set these up to grind on my lathe and take maybe 0.0005- 0.001 off each face would I be able to reuse these rotors? Also I'm assuming I need to offset the gear width as well?

Any thoughts?

Thanks

probably because of the bad bearing...

i would think that is useable, as that part of the rotor isn't supposed to touch anything, but i would double check the rotor to rotor housing width spec. also the rotor bearing clearance.

and then the side seal grooves have to be good too.

Any suggestions on total to take off? Was thinking about finding the works one and finishing to clean up and doing the same to the rest?

there is a spec for the rotor land to rotor side clearance.. it is important to re-establish this

how much you take and where depends on how the rotor measures up
