500 K0 Rusty Alternator Rotor
« on: March 14, 2019, 08:16:34 am »
I discovered that I have a fairly rusty alternator rotor (see photo).  Does this appear to be bad enough to need rust removal?
If so, shall I sandblast it or take a wire wheel to it?
Thank you.

Go nuts. The rust will not affect anything except appearance. You can't hurt it without really trying. Soaking in a rust remover will be OK. Same with a wire wheel, steel wool, Scotchbrite, abrasive blasting - just lay off the tapered hole as that's a precision fit on the crankshaft end.

Be advised DO NOT turn the engine over continuously with the alloy cover off or the oil gallery plug will disapear somewhere never to be found and a large slippery puddle apear on the floor!!

Lol! I primed my engine with a drill on that alternator nut....as soon as the pressure built I had oil all over me...then I spent the next hour going through my boxes of spare parts thinking I forgot to put that gallery plug in...eventually found it on the floor...
