Small update! Noisy bearing on alternator was driving me nuts. Made sure it was the bearing using the screwdriver as stetoscope :wink:
So, went to specialized shop, got the bearings and got on with it!
Found out it was impossible to take the alternator down with the headlight in place. The bottom screw is impossible to be reached. Undid it just through the headlight opening…
And it is out!
Took the pulley out. Nothing major there
Undid the four plus four screws holding the alternator together, but it was still seized. So, started to open it using the screw and nut. Wound up the screw and then hit it with a hammer on the oposite side!
Success! It started to open. Redid the procedure again.
And finally..!
Few hits with hammer and the old bearing is out
Now comes the funny part. Before started taking everything apart, put the new bearing in the freezer. There it was for two hours, I'd say at -20-ish C
After the old bearing was out, cleaned the housing and prepared it for the complete renewal.
Primed
And painted in sliver
Then I put it for 20 minutes in the owen warmed at 100C. The primary reason for that was not to cure the paint, but to strech it a bit.
It worked like a charm! The bearing eased itself in without hammer or any tools. Just a light push with finger and it was in
After that putting everything back together and voila!
Now, I intended to change both of the bearings, but when opened the alternator, was not sure about the back end. All the how to's and tutorials I could find dealt with Bosch or Valeo alternators and none with Mitsubishi which is installed in my car so didn't want to push my luck with it. So I just replaced the bad front bearing and put everything together and now it is working as intended. No more noise, engine is at tickover a beauty to listen to!
