hickabilly Posted June 22, 2009 Report Share Posted June 22, 2009 Replaced the belts the other day, and with the belt off, I noticed my alternator has some play in the rotating assembly. Is a bearing going bad? Is this even something to worry about? The alt works fine other than that, but it freaks me out a bit. I just want some confirmation before I go laying down the money for another one. Link to comment Share on other sites More sharing options...
Zack_Morris Posted June 22, 2009 Report Share Posted June 22, 2009 is it up and down play or in and out play? up and down is not good, a SMALL amount of in and out is normal Link to comment Share on other sites More sharing options...
Tim_C. Posted June 22, 2009 Report Share Posted June 22, 2009 Bearings need replaced. Don't run it like that for sure. Link to comment Share on other sites More sharing options...
jolyrgr Posted June 22, 2009 Report Share Posted June 22, 2009 Any alternator repair shop should be able to replace those easily and cheaply. Link to comment Share on other sites More sharing options...
hickabilly Posted June 22, 2009 Author Report Share Posted June 22, 2009 Yah, it's up and down play. Not really noticeable w/ the belt on b/c of the tension. But it's definitely obvious with the belt off. I'm not running it like that, largely because the car's still out of commission from the accident a few weeks ago, but I'll definitely get it fixed before I put the car back on the road. Thanks for the help. Link to comment Share on other sites More sharing options...
Tim_C. Posted June 22, 2009 Report Share Posted June 22, 2009 Any movement at all there is catastrophic. Chances are good there is damage to the rotor and stator. It may or may not be rebuildable. New bearings would be the minimum it requires. I would have a rebuild shop go through it and replace whatever they feel necessary. I do not recommend replacing with a store bought unit.

Do online parts providers count as "store bought units"? :biggrinumbrella1: I know of at least 2 guys in this thread that can hook you up with an alternator.

Tim_C. Posted June 23, 2009 Report Share Posted June 23, 2009 Do online parts providers count as "store bought units"? :biggrinumbrella1: No, your alternators are rebuilt by a pro, as are mine. That is the main goal. Have a professional you trust go through it, or supply another one. The store bought units from parts stores remove the good OEM parts inside, and install cheap replacements that will not last very long. Stay away from lifetime warranties too.
