So my tach stopped working... I was driving the car around the neighborhood trying to find the source of the grinding noise. I was driving the car like I stole it and all the sudden my tach goes all the way up to 5000 and then starts wigging out on me jumping all over the place. Then it just died.
I think my alternator is going out on me, so I am going to rebuild it. I looked up some articles on how alternators work and then proceeded to take mine apart:
Separated the stator and the rotor:
Using my harbor freight gear puller to pull off the bearings:
Using an impact wrench to zing off the pulley:
Taking note of the fan, woodruff key, and spacer order:
Using the gear puller to separate the front casing from the rotor:
Taking off the bearing cover:
TADA :twisted:! This bearing is DESTROYED. There were pieces of metal falling out, no grease, and the ball bearings don't even resemble spheres anymore. I think this is the source of that grinding/whining noise:
Using a socket to smack the bearing out because once again I don't own a press:
Here are both bearings in the alternator. Quite nasty:
Separating the back casing from the stator:
My current progress. The parts I ordered to rebuild the alternator have not come in yet, so I'm waiting:
Here is the car so far (front end make-over is on order):
So a cleaned up, painted, rebuilt alternator is in the works as well as a new front end... coming soon...
