these aren't fords bud. 148k on my original in my 2000 Camry. Only replace when it stops charging or makes noise. Not a maintainence item

 

Lol Ford. "Never again"

My oldest Denso got to 243.5k before it gave out. Just needs $10 worth of brushes and stuff. Maybe a bit more for a bearing as well.

 

98 5sfe and about 103K miles. Is it about time for a new alternator?

Mine has 234K and I have it apart for new brushes and bearings. Brushes are at the end of the spring capacity, so hard to say how long they'd continue to conduct power. Bearings were probably OK, but for the cost and having it apart anyway, I replaced. Rebuild cost was $27 including shipping.

Safely you can wait another 100K.

 

My alternator started to get weak a few months ago at 225k. I went ahead and replaced it with an OEM one with 110k on it and replaced the brushes. I originally replaced the brushes on my original one but it wasn't the actual issue for not giving enough power when everything was on. Once I replaced the alternator and put those brushes on it, it was all good.

 

2006 camry xle v6 74k alt was junk ive had 3 fords go 140k plus luck of the draw

 

I think gen5/6 4cyl Camrys are known to have alternator problems, yeah. Especially the bearing goes out, you start hearing a screeching/whining noise. My aunt has an '05, I replaced it with a TYC at 80k.

 

My 1987 Cressida is still what I think on the original alternator at 87K. 1985 Camry Alternator gave out at around 130K. 1998 V6 LE original gave out around 208K. 2004 SE I4 5SPD Manual original gave out around 160K~ when it was replaced and then the replacement gave out (diode) at around 7K. My 2004 XLE V6 original alternator died 65K~, replacement was swapped to troubleshoot a potential charging issue at some 90K~. That replacement diode went bad around 108K. IS250 original alternator gave out 131K.

 

Yeah, Toyota doesn't build them like they used to. Newer alternators tend to die early deaths, among other engine, water pump and transmission problems. But these old design alternators last just about forever, way better than the Delphi junk. You should inspect the brush assembly say 100-120K miles and change it if needed. It's about $15. Use a Gates Krikit-II belt tension gauge, keep the right tension, and the bearings should last a long time too.

 

Thanks for all discussion. Getting the belt gauge asap. I just willy nilly adjusted the power steering and alternator belts.

 

john, my 94 still has it's oem alternator and it has the manual tensioner screw setup.
my 06 is on it's 3rd alternator, all due to bearings, and it has the automatic belt tensioner spring.
so i'm gonna say that it's not all the belt tensions fault that these fail. did they stop using denso alt's at some point?

Gen 4 Densos will go about 250, then new brushes will take them another 100 or so, more if the armature is resurfaced.

1992 Camry 2.2 liter 180,000 miles original alternator

 

MIB, will putting the armature in a drill and spinning the copper commutators against fine sandpaper make a difference? it used to work on the PM DC generators but not tried it on AC alternators.

2000 camry at 130,000 miles, debating on whether to take it apart and replace the brushes (although I have never done that before)

 

Wait another 100k miles until/unless there is evidence of charging issue.
